Flashcards : Understanding Edema and Heart Failure Mechanisms — 20 cartes

Fluid buildup due to pressure, leakage, lymph failure, or low albumin.

Increased capillary pressure pushes fluid into tissue.

Increased capillary permeability due to injury or histamine.

Impaired lymph drainage prevents protein-rich fluid removal.

Low blood protein reduces osmotic water retention.

Dyspné and lungstuvning due to impaired left ventricular function.

Reduced ejection of blood from left ventricle.

Impaired filling of left ventricle.

Fluid leaks into alveoli, causing dyspné and possible edema.

Reduce angiotensin II and aldosterone, lowering blood pressure.

Vasoconstriction and stimulates aldosterone for fluid retention.

Increases sodium and water reabsorption in kidneys.

Patient education, salt/fluid management, monitoring weight.

Chronic bronchitis with mucus, and emphysema with alveolar destruction.

Mucus hypersecretion and airway inflammation.

Alveolar wall destruction, reduced recoil, air trapping.

Venous thrombus traveling to pulmonary arteries.

Anticoagulation, thrombolysis, or thrombectomy if severe.

Reduced renal perfusion decreases filtration rate.

Direct damage to kidney tissue impairing function.
