LV is less effective→ increase in pulmonary venous pressure → pulmonary vessels engorged→ fluid filled into lungs/alveoli → patient can’t breath properly

3
New cards

ADHF triggers

  • medication forgotten

  • arrhythmias

  • ischemia

  • lifestyle

  • uncontrolled HTN

  • renal failure

  • embolism

New cards

ADHF Progressive Manifestations

Early: pulmonary venous pressure increased causing increased respiratory rate

Later: interstitial edema = tachycardia → respiratory acidemia
