S 51 yr old man is undergoing abdominal surgery and becomes hypotensive while under general anesthesia. The patient had been doing well during most of the procedure but now has a blood pressure of 80/40 mm of Hg. His past medical history is significant for coronary artery disease and diabetes mellitus. A pulmonary artery catheter placed prior to the procedure gives the folowing data:
Central venous pressure 10mmHg
Pulmonary artery pressure60/30mmHg
Pulmonary capillary occlusion pressure 24mm Hg
Cardiac output 2.3L/min
Which of the following is the most likely diagnosis?
a acute left heart failure
b Acute mitral regurgitation
c. Acute right heart failure
d Hypoxic pulmoary vasoconstriction
e Sepsis syndrome

Normal CVP is 2-6 mm Hg . in this case it is elevated which may indicate Rt heart pathology or increased pressure in the pulmonary artery( which is elevated here]. DDD

I think D may be a 2ndary to C + Hx of CAD + DM --So I say C

The ans is a..the pat has high filling pressure and low cardiac output..thereby indicating cardiogenic shock. Cardiogenic shock could be due to a variety of reasons but the end result is left ventricular failure. This accounts for the secondarily high right sided pressures and filling pressures( left sided failure causes right sided failure).

a... just look for Pulmonary capillary occlusion pressure 24mm Hg... which is high. so cardiogenic shoch , here, it is dueo to LVF.

is Pulm Cappilary occlusion pressure sam as PCWP?
