Vital(BP): hypo, hyper. PEx(JVP): volume status -------------------------------- 1st. PI(3-7)= contractility and volume status(high volume only cause high PI) overload = high PI. low volume = low PI. (=low volume = low preload = RV failure, arrhythmia same thing) HTN = low PI low BP = low PI. (only overload cause high PI = with high preload, but otherwise, BP, volume => cause low PI) 2nd. Flow(4-6) overload, 3rd. Power(surge = only thrombus, 4-6) hypotension route (BP) => high VADFL = vasodilator, sepsis = R/O => low VADFL(most common) with high JVP => RV failure, PE/tamponade, pneumothorax , then adjust LVAD(higher) ...
