CHF Flashcards
Final
Can a heart attack cause heart failure?
Yes
What is heart failure?
When the heart pumps blood inadequately, leading to reduced blood flow to tissue, backing up blood in veins and lungs, making the heart even more weak.
Where does left heart failure go?
Lungs
Where does right heart failure go?
edema in body
S/S Left sided heart failure
Paroxysmal nocturnal dyspnea (SOB and coughing at night)
Pulmonary congestion
- cough
- crackles
- wheezes
- blood-tinged sputum
- tachypnea
Restlessness
Confusion
Tachycardia
Exertional dyspnea
Fatigue
Cyanosis
S/S of right sided heart failure (Cor Pulmonale)
Fatigue
Increased peripherla venous pressure
Ascites
Enlarged liver and spleen
Distended jugular veins
Anorexia
GI distress
Weight gain
Edema
First signs of Dig toxicity
Abdominal pain
Anorexia
N/V
Visual disturbances-yellow aura
Bradycardia/arrhythmias
Medications for CHF
- Vasodilators
- Diuretics
- Morphine
- Angiotensin-converting enzyme inhibitors
- Angiotensin II receptor blockers
- Beta-Blockers
- Digitalis
- Anticoags
- Other dysrhthmics
Assessment for CHF
Health history
Sleep & activity
Diet
Knowledge and coping
Physical exam
- mental status
- lung sound: crackles & wheezes
- Heart sounds: s3, s4
- Fluid status/signs of fluid overload (daily weight, I&O)
-Assess responses to medications
PCs of CHF
- Pleural effusion
- Dysrhythmias
- Thromboembolism
- Pericardial effusion and cardiac tamponade
- Enlarged liver
- Renal liver
- Cardiogenic shock
What is pulmonary edema?
Acute event-lung volume can’t handle an overload of blood volume.
Pressure increases in pulmonary vasculature, causing fluid to move out of the capillaries and into interstitial space of the lungs and alveoli=hypoxia.
S/S of pulmonary edema
Restlessness Anxiety Dyspnea Cool/clammy skin Cyanosis Weak and rapid pulse Cough Lung congestion (moist, noisy respirations) Increased sputum production (frothy and blood-tinged) Decreased LOC
Management of CHF
Prevention
Early Recognition
-monitor lung sounds and signs of decreased activity tolerance and increased fluid retention
Patient in upright position and dangle legs Minimize exertion and stress Oxygen Meds -mophine -diuretics (furosemide)
Treating CHF
Upright Position Nitrates Lasix Oxygen Ace inhibitors Digoxin
Fluids (decrease)
Afterload (decrease)
Sodium restriction
Test (Dig level, ABGs, K level)
Cardiac classifications (NY Heart Association)
Class I-no s/s
Class II-ADLs ok, gets winded with exertion
Class III-Trouble completing ADLs
Class IV-SOB even at rest
