Cardiovascular

Question 1

LVF—> RVF patho

Answer 1

Increased LVF and arterial pressures are reflected back into plum circulation
Increased pulmonary vascular resistance and pressure
RV hypertrophy

Question 2

Pulmonary hypertension

Answer 2

High pulm pressure—>increased RV afterload—>myocardial hypertrophy—> increased wall thickness and decreased filling volumes—>diastolic dysfunction

Question 3

Pulmonary disease

Answer 3

Decreased gas exchange—>alveolar hypoxia and hypoxemia—> vasoconstriction —>increased RV and PVR afterload—> decreased CO and EC

Question 4

Pulm disease decreased CO and EF

Answer 4

Increased residual volumes—> increased preload—> back up of pressures into systemic veins—> increased hydrostatic pressure in peripheral caps—> peripheral edema
