Decreased Cardiac Output Nursing Diagnosis & Care Plan

The heart is not moving enough blood to meet the body's demands. Output falls, perfusion drops, and the organs downstream start to fail. Your job is to catch the slide early, support output and oxygenation, and treat the cause before the damage becomes irreversible.

What is Cardiac Output?

Cardiac output is the volume of blood the heart pumps per minute. It is the product of heart rate (beats per minute) and stroke volume (the volume ejected per beat): cardiac output = heart rate x stroke volume, expressed in liters per minute (L/min).

A healthy adult at rest runs 4 to 6 L/min, though age, body size, and activity shift the range. Elite athletes can exceed 35 L/min during exercise.

Heart rate is set by the sinoatrial (SA) node under push and pull from the sympathetic and parasympathetic systems, with input from the central nervous system and the baroreceptors. Baroreceptors sit in the aortic arch and in both internal carotid arteries and respond to changes in blood pressure:

• Hypertension. Baroreceptors fire faster, driving parasympathetic activity and inhibiting sympathetic response, which lowers heart rate and BP.
• Hypotension. Less baroreceptor firing cuts parasympathetic activity and boosts sympathetic response, raising BP through vasoconstriction and a faster heart rate.

Stroke volume depends on three factors:

• Preload. The stretch of the ventricular fibers at the end of diastole, set by the volume in the ventricle at that point. More filling, more stroke volume.
• Afterload. The resistance the ventricle ejects against. It works inversely to stroke volume: arterial vasoconstriction raises afterload and drops stroke volume, vasodilation does the reverse.
• Contractility. The force the myocardium generates. More contractility, more stroke volume.

Measuring Cardiac Output

Several methods measure cardiac output. Choose based on invasiveness, accuracy, whether it reads continuously in real time, whether it can be calibrated to a reference method, and what other hemodynamic data it gives you.

Invasive:

• Pulmonary artery thermodilution. Inject cold saline through a PAC and measure the temperature change as the blood moves past a thermistor-tipped catheter.
• Transpulmonary thermodilution. A central venous catheter injects the thermal indicator and a thermistor-tipped arterial catheter, usually placed in the abdominal aorta through the femoral artery, records the thermodilution curve.
• Lithium dilution. Isotonic lithium chloride injected into a central or peripheral vein serves as the indicator; output is read at a peripheral arterial catheter.

Minimally invasive:

• Invasive pulse wave analysis. Estimates stroke volume and output continuously from the arterial pressure waveform.
• Esophageal Doppler. Estimates stroke volume from blood flow velocity in the descending aorta, read by a Doppler probe.

Non-invasive:

• Doppler ultrasound. Uses the Doppler shift from blood moving through the heart to calculate flow velocity and volume.
• Fick method. Calculates output from oxygen consumption and the arterial-venous oxygen difference.
• Arterial pulse contour analysis. Calculates output from the shape and strength of the arterial pulse wave.

Cardiac output drops when the heart cannot meet the body's metabolic demand. Myocardial infarction, heart failure, dysrhythmias, and fluid volume problems are common drivers.

Causes of Decreased Cardiac Output

Common causes include myocardial infarction, hypertension, valvular and congenital heart disease, cardiomyopathy, heart failure, pulmonary disease, arrhythmias, drug effects, fluid overload, decreased fluid volume, and electrolyte imbalance. The mechanisms behind them:

• Altered rate, rhythm, or conduction. Any electrical disturbance breaks the coordinated contraction, dropping output.
• Cardiac muscle disease. Cardiomyopathy or myocarditis weakens the pump.
• Decreased oxygenation. Coronary artery disease or respiratory disorders starve the myocardium.
• Impaired contractility. Infarction or heart failure weakens the force of contraction.
• Increased afterload. Hypertension or aortic stenosis makes the heart work harder against resistance.
• Altered preload. Too much or too little ventricular filling changes how much the heart can eject.

Nursing Care Plans and Management

Care centers on optimizing cardiac function, controlling symptoms, educating the patient and caregiver, and preventing complications.

Nursing Problem Priorities

Protect oxygenation and tissue perfusion so every organ keeps getting oxygen and nutrients. Track the downstream effects of low perfusion, since poor flow compromises organ function fast. Manage nutrition and fluid balance, since low output drives either fluid retention or hypovolemia and the patient often carries a sodium restriction.

Nursing Assessment

Assess to find what drove the drop in output and to catch any change during care. Decreased cardiac output shows up as:

• Abnormal heart sounds (S3, S4)
• Angina
• Anxiety, restlessness
• Change in level of consciousness
• Crackles, dyspnea, orthopnea, tachypnea
• Decreased activity tolerance
• Decreased peripheral pulses; cold, clammy skin; poor capillary refill
• Decreased venous and arterial oxygen saturation
• Dysrhythmias
• Ejection fraction less than 40%
• Fatigue
• Hypotension
• Increased central venous pressure (CVP)
• Increased pulmonary artery pressure (PAP)
• Tachycardia
• Weight gain, edema, decreased urine output

Nursing Diagnosis

Common nursing diagnoses for decreased cardiac output:

• Decreased Cardiac Output related to altered heart rate and rhythm secondary to atrial fibrillation, as evidenced by irregular pulse, palpitations, and fluctuating blood pressure.
• Decreased Cardiac Output related to decreased stroke volume secondary to myocardial infarction, as evidenced by weak peripheral pulses, delayed capillary refill, and cool extremities.
• Decreased Cardiac Output related to increased afterload secondary to systemic hypertension, as evidenced by diminished pulse pressure, cyanosis, and fluid retention.
• Decreased Cardiac Output related to reduced contractility secondary to cardiomyopathy, as evidenced by poor tissue perfusion, lethargy, and dizziness.
• Decreased Cardiac Output related to ineffective ventricular filling secondary to pericardial effusion, as evidenced by jugular vein distension, shortness of breath, and reduced exercise tolerance.
• Decreased Cardiac Output related to impaired myocardial function secondary to congestive heart failure, as evidenced by cyanotic nail beds, cold clammy skin, and decreased oxygen saturation.

Nursing Goals

Goals and expected outcomes:

• The patient maintains adequate cardiac output: blood pressure, pulse rate, and rhythm within normal parameters, strong peripheral pulses, and activity tolerated without dyspnea, syncope, or chest pain.
• The patient has warm, dry skin and eupnea with no pulmonary crackles.
• The patient stays free of side effects from the medications used to maintain output.
• The patient explains the actions and precautions for cardiac disease.

Nursing Interventions and Actions

1. Assessing and monitoring cardiac output

Sharp assessment catches complications early and lets you act before they escalate.

Assess heart rate and rhythm. Compensatory tachycardia is a common response to low blood pressure. It helps output at first but harms it when it persists. Count the apical pulse at the point of maximal impulse (PMI) for a full minute while palpating the radial pulse. Watch for dysrhythmias, which can fire the ventricles prematurely before diastole finishes.

Auscultate blood pressure and check for orthostatic hypotension. Orthostatic hypotension is a sustained drop of at least 20 mm Hg systolic or 10 mm Hg diastolic within 3 minutes of moving from lying or sitting to standing. In cerebrovascular disease it usually reflects a large drop in preload. Lay the patient supine for 10 minutes before the first BP and heart rate, then sit them with legs dangling for 2 minutes and reassess both.

Check peripheral pulses. Weak pulses point to reduced stroke volume and output. Palpate all arterial pulses (temporal, common carotid, brachial, radial, femoral, popliteal, dorsalis pedis, posterior tibial) with light pressure, comparing extremities side by side.

Assess jugular vein pulsations. With normal blood volume, the jugular veins are visible supine with the head of the bed at 30°. Obvious distension with the bed at 45° to 90° suggests raised CVP and right-sided heart failure.

Perform the capillary refill test. Prolonged refill means inadequate arterial perfusion to the extremities. Compress the nail bed until it blanches, release, and time the return of color. Normal is within 2 seconds. Do not base clinical decisions on capillary refill alone.

Auscultate heart sounds for gallops (S3, S4) and listen to the breath sounds. A new gallop, tachycardia, and fine crackles at the bases signal heart failure starting. Pulmonary edema brings coarse crackles on inspiration and severe dyspnea. S3 reflects reduced left ventricular ejection and is a classic sign of left ventricular failure; S4 reflects reduced left ventricular compliance that impairs diastolic filling. Gallops are very low-frequency; use the bell held lightly against the chest.

Note skin color, temperature, and moisture. Cool skin and diaphoresis point to low output driving sympathetic vasoconstriction, often with cardiogenic shock or acute MI.

Check level of consciousness. Irritability, restlessness, and poor concentration reflect reduced cerebral perfusion and hypoxia. Older adults are especially vulnerable. Mental status changes can come from poor cerebral perfusion or stroke, sometimes alongside dyspnea or anxiety.

Note respiratory rate, rhythm, and breath sounds. Shallow, rapid breathing is typical of low output, and crackles signal fluid backing up from poor left ventricular emptying. Low-preload states cause dyspnea at rest and with exertion, and acute hypovolemia from poor intake, sweating, diarrhea, or hemorrhage makes it worse.

Identify paroxysmal nocturnal dyspnea (PND) or orthopnea. PND tracks closely with low output. Overnight, peripheral edema reabsorbs and floods the circulation, worsening pulmonary congestion until the patient bolts upright gasping for air. Orthopnea eases on sitting up; PND can take 30 minutes or more upright to relieve.

Assess oxygen saturation by pulse oximetry at rest, during ambulation, and after. A drop in saturation is one of the earliest signs of falling output. Patients with mild to moderate heart failure may read normal at rest but desaturate with exertion or when lying flat.

Determine the pattern of sleep and rest. Sleep events worsen cardiac disease, especially heart failure. A sudden fluid shift raises preload and congests the lungs, disrupting sleep through PND or sleep-disordered breathing. Loud disruptive snoring and apnea lasting 10 seconds or more are the cardinal signs of obstructive sleep apnea.

Assess chest pain. Note location, radiation, severity, quality, duration, associated nausea, and what brings it on or relieves it. Chest pain usually means myocardial ischemia, blood supply failing to meet myocardial oxygen demand, which compromises output. Angina is the most common sign of that ischemia.

Place the patient on a cardiac monitor and watch for dysrhythmias, especially atrial fibrillation. Atrial fibrillation is common in heart failure and can throw a thromboembolic event. Continuous monitoring tracks the rhythm in real time at the bedside and the central station.

Monitor bowel function, give stool softeners as ordered, and tell the patient not to strain. Inactivity causes constipation, and straining (the Valsalva maneuver) can trigger dysrhythmia, drop cardiac function, and in some cases cause death. Use extra caution with pre-existing coronary, valvular, or congenital heart disease.

Watch adherence to the regimen, including medications, activity, and diet. Nonadherence to diet and medication can turn the patient fast, so close observation and followup matter.

Check BP, pulse, and condition before giving cardiac medications such as ACE inhibitors, digoxin, and beta-blockers like carvedilol. Assess tolerance before dosing, but do not hold medications without provider input; notify the provider if heart rate or BP is low. The provider may still want the dose given. Antiarrhythmics can depress the heart and provoke arrhythmias, and calcium channel blockers can worsen heart failure.

Track fluid balance and weight, weighing the patient regularly before breakfast. Weight is a more sensitive marker of fluid or sodium retention than intake and output. Primary prevention targets a body mass index under 25 kg/m².

Check for pedal and sacral edema. Edema is a defining sign of heart failure, in the feet, ankles, and legs, and in the sacral area for patients on bed rest. Test for pitting by pressing firmly with your thumb over the dorsum of the foot, behind the malleolus, over the shins, or the sacrum for 5 seconds, and grade by depth and how long the indentation lasts.

Monitor urine output, measuring hourly if the patient is acutely ill. Output is a direct read on cardiac function: low output means poor renal perfusion and less urine. If output drops, check for a distended bladder or trouble voiding.

Assess B-type natriuretic peptide (BNP). BNP is secreted mainly from the ventricles in response to increased preload and rising ventricular pressure. It climbs as the ventricular walls stretch, making it a useful diagnostic, monitoring, and prognostic marker in heart failure.

If hemodynamic monitoring is in place, track CVP, pulmonary artery diastolic pressure (PADP), pulmonary capillary wedge pressure (PCWP), cardiac output, and cardiac index. CVP reflects right-sided filling; PADP and PCWP reflect left-sided volumes; output gives an objective number to guide therapy. The longer these catheters stay in, the higher the infection risk, so handle them only when competent to do so.

Watch closely for signs of heart failure and falling output. Tachycardia, venous congestion such as edema, and fatigue from low output are the markers. Breathlessness is the cardinal sign of left ventricular failure and worsens progressively.

Assess for fatigue and reduced activity tolerance. Fatigue and exertional dyspnea are common in low-output states. Track the response to activity to guide how fast to advance it. As left ventricular failure progresses, less and less exertion brings on breathlessness.

Identify contributing factors so you can target the care plan. Cardiac function fails through many mechanisms: hypertension, coronary disease, congenital problems, ischemia, infarction, heart failure, shock, arrhythmias, genetic disease, structural abnormalities, pericardial effusion, emboli, and tamponade.

Monitor the ECG for rate, rhythm, and ectopy. Dysrhythmias arise from low perfusion, acidosis, or hypoxia, and tachycardia, bradycardia, and ectopic beats all cut output further. Older adults are prone to losing atrial kick in atrial fibrillation. The 12-lead ECG diagnoses dysrhythmias, conduction problems, chamber enlargement, ischemia, injury, infarction, and the cardiac effects of electrolyte disturbances and antiarrhythmics.

Review the ECG and chest X-ray. The ECG can reveal a prior MI or left ventricular hypertrophy from aortic stenosis or chronic hypertension. The chest X-ray can show pulmonary edema, pleural effusions, or an enlarged cardiac silhouette from dilated cardiomyopathy or a large pericardial effusion.

Examine labs, especially arterial blood gases (ABG) and electrolytes including potassium. Patients on cardiac glycosides face higher toxicity risk with hypokalemia, which is common from diuretic use. Order an ABG for severe respiratory distress, hypoxemia not corrected by supplemental oxygen, or evidence of acidosis.

Monitor CBC, sodium, BUN, and serum creatinine. A low serum sodium often appears in advanced heart failure and signals a poor prognosis. Creatinine and BUN rise with severe failure from reduced renal perfusion, and creatinine can also rise from ACE inhibitors or overaggressive diuresis.

Assess available social support. Complex cardiovascular disease may need implantable defibrillators or left ventricular assist devices, and a strong support system eases self-care and is linked to better cardiovascular outcomes.

2. Promoting tissue perfusion and venous return

Low output cuts oxygen delivery, driving tissue hypoxia and organ dysfunction. Monitor vitals closely and watch for signs of poor perfusion.

Run a 6-minute walk test. Have the patient walk as far as tolerated over 6 minutes while you watch for symptoms. Document distance covered, pre- and post-exercise heart rate, and the response.

Position the patient to ease breathing. Add pillows, raise the head of the bed, or move the patient to a recliner. These positions cut venous return and preload, ease pulmonary congestion, and take pressure off the diaphragm. Support the lower arms on pillows to spare the shoulder muscles.

Match position to the problem. For fluid overload, place the patient in semi-Fowler to high-Fowler to cut preload and ventricular filling. For hypovolemia, supine positioning boosts venous return and promotes diuresis. Either way, avoid compressing major vessels with pressure on the chest or abdomen.

During acute events, keep the patient on bed rest or at an activity level that does not compromise output. In severe heart failure, restricting activity buys temporary recompensation. Teach the patient to balance rest with activity, sitting to chop vegetables, dry their hair, or shave, and to avoid strenuous activity, isometric exercise, and competitive sports.

Encourage exercise training as indicated. A supervised program of endurance and resistance work focused on the core and lower body offers the most benefit, and fitness can raise stroke volume over time. Start with a horizontal mode like swimming or a recumbent cycle, three times a week.

Use music therapy to lower anxiety and support cardiac function. Music can balance brain waves and activate the limbic system, relaxing the patient, shifting stress hormone release, and prompting nitric oxide that relaxes vessel tone and lowers blood pressure.

Teach maneuvers that counter orthostatic hypotension. For acute symptoms, coach physical countermeasures that boost venous return: leg crossing, muscle tensing, muscle pumping by sway-and-shift or tiptoe walking, bending forward, sitting or squatting or lying supine, squeezing a rubber ball while contracting the leg and abdominal muscles, breathing techniques, buttock clenching, sitting with the head between the knees, and skin-surface cooling.

Deflate the balloon tip after measuring pulmonary artery wedge pressure (PAWP). PAWP is read by inflating the balloon to wedge it in a smaller branch of the pulmonary artery, which occludes flow. Confirm the catheter has returned to position by the pulmonary artery pressure waveform on the monitor.

Apply waist-high compression stockings or abdominal binders as indicated. Waist-high compression (30 to 40 mm Hg) cuts venous pooling and protects stroke volume and perfusion when the patient is upright. Tight abdominal binders work too, since the lower abdomen and pelvis hold 20 to 30% of total blood volume.

Give oxygen as prescribed. The failing heart may not meet rising oxygen demand. Keep saturation above 90%. If it falls below 90%, oxygen and noninvasive positive pressure ventilation (NIPPV) support the patient and help avoid intubation.

Give medications as prescribed, watching for side effects and toxicity. Depending on the cause, common agents include digitalis, diuretics, vasodilators, antidysrhythmics, ACE inhibitors, and inotropes. Antiarrhythmics control the rhythm disturbance driving low output.

3. Managing angina or chest pain

Angina is myocardial ischemia from a mismatch between blood supply and oxygen demand. A faster heart rate and stronger contractions raise demand, and so does rising afterload and preload through higher myocardial wall tension.

If chest pain appears, have the patient lie down, monitor the rhythm, give oxygen, run a strip, medicate the pain, and notify the provider. These steps raise oxygen delivery to the coronary arteries and improve the outlook. Report the symptoms at once, since they can signal ischemia. The goal is to relieve the pain, slow progression, and head off ischemia or sudden death.

Position the patient in semi-Fowler during acute angina. Have the patient stop all activity and rest in semi-Fowler to cut the oxygen demand on the ischemic myocardium.

Encourage smoking cessation. Quitting sharply reduces the acute cardiac effects of smoking and allows slow reversal of atherosclerosis. Push it hard and support the patient through followup.

Promote a diet low in saturated fat and sodium. Build the diet around vegetables, fruit, and dairy. Replace saturated and trans fats with unsaturated fats like fish and nuts, restrict salt, keep micronutrient intake adequate, and avoid carbonated drinks.

Schedule rest and activity together. Once you know the activity level that triggers pain, plan around it. If pain comes with minimal activity, alternate activity with rest. Balancing the two is central to teaching the patient and family.

Tell the patient to avoid temperature extremes. Extremes, especially cold, can trigger angina. When exercising, avoid direct sunlight or a small air-conditioned room.

Give medications as prescribed. The goal of drug therapy in angina is to cut morbidity and prevent complications.

• Nitroglycerin. Sublingual nitroglycerin is the mainstay, used for acute relief and prophylactically before activities that provoke angina. If chest pain is unchanged or only partly relieved, give it for up to 3 doses.
• Beta-blockers. Used for symptom relief and to prevent ischemic events by lowering myocardial oxygen demand, heart rate, and contractility. They also cut mortality and morbidity after acute MI.

Give oxygen as indicated. Administer oxygen if the respiratory rate climbs or saturation drops, usually 2 L/min by nasal cannula even without clear desaturation.

Prepare the patient for revascularization as appropriate. Consider it in patients with left ventricular dysfunction and severe symptoms despite maximum medical therapy. The two main procedures are percutaneous transluminal coronary angioplasty and coronary artery bypass grafting (CABG).

Assist with implantable cardioverter defibrillators (ICD). The ICD detects and stops life-threatening ventricular tachycardia or fibrillation. A generator about the size of a matchbook sits in a subcutaneous pocket in the upper chest, with a transvenous right ventricular lead that senses electrical activity and delivers an impulse.

4. Maintaining fluid and nutrition balance

Patients with low output usually carry dietary and fluid restrictions, especially on sodium and fluid. Work with a dietitian on a heart-healthy plan, teach the modifications, and track nutritional status and intake and output.

Watch for fluid overload or dehydration. Catching fluid imbalance early lets you act before complications set in. New or worsening symptoms often go unrecognized, delaying lifesaving treatment.

Check fluid responsiveness before fluid management. A passive leg raise that changes cardiac output defines volume responsiveness and tests fluid loading. Assess the response to the intervention.

Elevate the head of the bed and assist with activities of daily living. Raising the bed cuts preload, easing the work of pumping. Assisting with ADLs conserves energy and spares the heart exertional stress.

Monitor fluid intake including IV lines, and hold to a fluid restriction if ordered. Poorly functioning ventricles do not tolerate added volume. In congestive heart failure, fluid retention follows the low output caused by left ventricular failure, so restriction is warranted.

For increased preload, limit fluids and sodium as ordered. Restriction cuts extracellular volume and the load on the heart. The usual targets are a sodium restriction of 2 to 3 grams per day and, when status cannot be controlled despite sodium restriction and high-dose diuretics, a fluid restriction of 2 liters per day.

Offer small, frequent, nutrient-dense meals. Smaller meals are easier on the heart than large ones, and nutrient-dense food meets needs without overloading the cardiovascular system.

Avoid additives and processed foods. Additives like sodium alginate, sodium benzoate, and disodium phosphate raise daily sodium intake.

Respect food preferences. Tailor counseling and handouts to the patient's and family's preferences and involve the family in teaching. Flavorings like lemon juice, vinegar, and herbs improve taste and help the patient accept the diet.

Teach label reading. On low-sodium diets, check labels for "salt" and "sodium," especially on canned foods. Potato chips actually carry less sodium than a cup of canned mushroom soup, though they still do not belong in a low-sodium diet.

Caution against large water intake and over-the-counter medications. Municipal water and water softeners both add sodium. Warn against nonprescription antacids, cough syrups, and laxatives.

Give colloids or crystalloids as prescribed. Hypertonic saline and colloids like albumin can boost intravascular volume, as can mannitol. Isotonic saline is problematic because it limits achieving a negative fluid balance.

Give vasopressors as indicated. Vasopressors such as norepinephrine, vasopressin, or terlipressin keep systemic arterial pressure above pulmonary arterial pressure in acute ventricular failure. Norepinephrine restores mean arterial pressure to baseline, lowers biventricular filling pressure, and raises cardiac index. In pulmonary embolism, dobutamine improves hemodynamics and lowers pulmonary vascular resistance.

5. Teaching emergency cardiac support

CPR keeps blood flowing to vital organs until effective circulation returns. Teach it to professionals and caregivers alike; bystander CPR raises survival from cardiac arrest two to three times.

Assess responsiveness and breathing. Rescuers often struggle to find a pulse, delaying or skipping CPR. Lay rescuers should recognize arrest from level of consciousness and breathing effort; professionals add a pulse check.

• Lay rescuers: if the patient is unresponsive with absent or abnormal breathing, assume cardiac arrest, call for help, and start CPR.
• Professionals: check quickly for a pulse and start compressions when one is not definitely felt.

Activate the emergency response system. Inside a facility, call the team (Code Blue or Code 4). Outside, call 911 for EMS. If a lone rescuer must leave to call, prioritize activating EMS, then return at once for CPR.

Start CPR once arrest is recognized. Prompt CPR is the single most important step for survival and neurological outcome. Lay rescuers may do compression-only CPR; professionals give 30 compressions and 2 breaths.

• Put the patient on a firm surface such as the floor or a cardiac board.
• Place one hand on the lower half of the sternum, the other hand on top.
• Compress 2 inches deep at 100 to 120 compressions per minute, allowing full recoil between compressions.
• Switch providers every 2 minutes to keep compressions effective.
• Minimize interruptions for provider switches or pulse checks.

Give rescue breaths as appropriate. Recommended only when delivered by a healthcare provider, started after compressions. Open the airway with a head-tilt/chin-lift, clear any obstruction, and ventilate with a bag-valve mask, mouth-mask device, or oropharyngeal airway.

Defibrillate as soon as an AED is available. Apply the pads, let the device analyze the rhythm, and shock if indicated. Survival falls with every minute defibrillation is delayed.

Assist with placing an advanced airway as appropriate. An ET tube secures the airway and ventilation. Confirm placement by auscultating breath sounds, watching chest expansion, and using a carbon dioxide detector, with a chest X-ray afterward to confirm position.

Provide close post-resuscitation monitoring. After transfer to the ICU, keep continuous ECG and frequent BP checks until the patient is hemodynamically stable. Post-arrest care drives survival, so identify and treat the cause promptly.

6. Patient and caregiver education

Patients and families often understand little about the condition. Teach the disease process, treatment, lifestyle changes, and warning signs so the patient can manage it.

Set up an emergency plan, including CPR. Persistent low output can be fatal. During manual CPR, compress at least 2 inches (5 cm) deep, avoid exceeding 2.4 inches (6 cm), and keep the rate at 100 to 120 per minute.

Assess whether the patient and family can recognize cardiac symptoms. Recognizing symptoms and the right response is central to home care. The main barriers are not knowing the symptoms, blaming them on something benign, denying their importance, and embarrassment.

Assess and build on the patient's and caregiver's understanding of the disease and regimen. Start by checking what they know, correct misinformation, and explain in plain terms without frightening them.

Have the patient use a commode or urinal rather than a bedpan. Getting up to a commode stresses the heart no more than using a bedpan, while cutting the complications of immobility and preserving dignity and independence.

Encourage a healthy lifestyle, with smoking cessation and avoiding alcohol. Smoking raises heart failure risk, and the risk falls the longer the patient stays quit. Discourage any heavy drinking. Both improve cardiac output and overall health.

Educate the patient and family on the disease, its complications, the medications, daily weights, and when to call the provider. Early symptom recognition speeds treatment. Offer ongoing support and invite questions. Patients who do not see the link between risk factors and disease are less likely to change their habits or manage the illness.

Help the family adapt daily routines to support better cardiac function. Returning home can revive risk factors like a poor diet. A home or transitional care referral is usually unnecessary unless the patient is hemodynamically unstable with significant symptoms.

Teach how to fold in lifestyle changes. Psychoeducational programs with stress management and health education cut long-term mortality and reinfarction. Teach the family how to lower the risk of recurrence, including an emergency action plan and CPR training.

Provide emotional support. Stay calm, offer to stay with the patient for reassurance, listen to concerns, and answer questions with clear, accurate information. Help the patient name their emotions (anger, frustration, anxiety) and connect them with support groups or counseling.

6.1. Caring for an implantable cardiac device (ICD)

Teach the patient to prevent infection at the site. Check the site for redness, swelling, and heat, and take a daily temperature at the same time, reporting any rise. Avoid soaking in tubs, and skip lotions and powders on the area early on. Avoid tight clothing that rubs the site.

Teach pulse checks. Have the patient check the pulse daily and report any sudden slowing or rise, which can mean device malfunction.

Explain electromagnetic interference. Avoid large magnetic fields such as MRIs, large motors, arc welding, and electrical substations, which can deactivate the device. Show an ID card at security gates and request a hand search, and carry a provider's letter confirming the ICD.

Teach activity limits. Restrict arm movement until the incision heals: do not raise the arm above the head for two weeks, and avoid heavy lifting for a few weeks. Continue prescribed physical activity, but skip contact sports.

Provide safety measures. Have the patient log ICD discharges and what triggered the sensation of shock, which helps the provider adjust the regimen. Provide a medical alert bracelet with the provider's information, and have the patient carry identification listing the device type and model, manufacturer, and the hospital where it was placed.

Explain the device's effect on family. Anyone in contact with the patient when a shock fires will feel it too, but it will not harm them. Reassure them rather than frighten them, and make sure sexual partners know.
