Q

What does congestion leads to in CHF? And why does it result?

A

It leads to edema as a result of an increased hydrostatic pressure in circulation

Q

What is the patho physiology of left sided heart failure?

A

LV does not eject sufficient volume - residual volume in LV - LA pumps harder to empty blood into LV - LA fails to fully empty - LA unable to receive full pulmonary return - pulmonary congestion and edema - RV workload increases - RV hypertrophys

Q

What is the patho physiology of right sided heart failure?

A

The RV is unable to pump sufficient volume into pulmonary circulation - congestion in RV - RA unable to fully empty into RV and works hard to push blood into RV - systemic circulation does not empty properly into RA - congestion and edema occur in systemic circulation due to increased hydrostatic pressure
