Study Notes
Heart Failure (Cardiac Insufficiency)
- Definition: Heart failure is a condition where the heart is unable to pump sufficient blood to meet the body's metabolic needs, causing circulatory congestion.
- Impact: Can affect either or both sides of the heart, leading to pulmonary and peripheral edema, fatigue, and shortness of breath.
- Etiology: Involves multiple causes, including congenital defects, diseases affecting the cardiovascular system (e.g., atherosclerosis, myocardial infarction, hypertension), and conditions that increase cardiac workload (e.g., infection, hyperthyroidism).
Clinical Manifestations
- Symptoms include decreased cardiac output, fatigue, anginal pain, anxiety, oliguria, and weight gain.
- Left Ventricular Failure: Characterized by an inability to pump oxygenated blood effectively, leading to symptoms such as pulmonary congestion, orthopnea, and dyspnea on exertion.
- Right Ventricular Failure: Associated with fluid accumulation in the body, often presenting as dependent edema, weight gain, and abdominal distension.
Assessment
- Subjective Data: Focus on symptoms like activity intolerance, edema, and how heart failure impacts daily living.
- Objective Data: Assess for signs of decreased renal perfusion (e.g., oliguria), peripheral and gastrointestinal congestion, and jugular vein distension.
Diagnosis of Congestive Heart Failure
- Diagnosis includes physical examinations, chest X-rays (showing heart enlargement and fluid), ECG (to rule out myocardial infarction), and echocardiography (to assess cardiac function).
- Lab tests: Elevated BNP indicates heart failure severity; serum electrolytes and kidney function tests help assess overall health.
Medical Management
- Goals include reducing heart workload and improving pumping ability.
- Drug therapy modifications include medications like digoxin and diuretics to enhance cardiac output and manage congestion.
- Lifestyle modifications involve dietary changes (e.g., low sodium) and fluid restrictions.
Nursing Interventions
- Monitor vital signs for signs of pulmonary edema (e.g., crackles, cough, oxygen saturation).
- Assess and address fluid retention through daily weights and abdominal girth measurements; elevate patient’s legs to reduce edema.
- Provide emotional support, education on medication adherence, and dietary restrictions to enhance patient knowledge and coping.
Pulmonary Edema
- Definition: Accumulation of extravascular fluid in the lungs, primarily caused by left-sided heart failure.
- Pathophysiology: Fluid buildup decreases gas exchange efficiency in the lungs, leading to severe respiratory distress.
Clinical Manifestations
- Symptoms include severe dyspnea, pink frothy sputum, and signs of agitation and restlessness.
- Objective findings may include tachypnea, tachycardia, and audible wheezes.
Assessment and Diagnostic Tests
- Diagnosis established through physical examination, chest X-ray, and arterial blood gas analysis to assess oxygenation and acid-base balance.
Medical Management of Pulmonary Edema
- Immediate treatment focuses on oxygenation, improving cardiac output, and reducing pulmonary congestion.
- Positioning: High Fowler's position promotes lung expansion and reduces venous return.
- Medication: Morphine sulfate can alleviate anxiety and improve preload; diuretics manage fluid overload.
Nursing Priorities for Pulmonary Edema
- Interventions include administering supplemental oxygen and monitoring cardiac status (vital signs, lung sounds).
- Patient education emphasizes understanding of medications, recognizing worsening symptoms, and the importance of reporting any concerning changes.
