Question

Evaluate the following data and determine which of the following are correct for a 75 kg male. Cardiac output = 2.5 liters/min, Heart rate = 115/min, ABP = 80/40, CVP = 0 mm Hg, EF = 70%, PAP = 12/5, PCWP = 2.   

The patient is under-perfusing their tissues A= true B= false

The patient's hemodynamic picture is primarily due to decreased preload

The patient's hemodynamic picture is due to increased afterload

The patient's hemodynamic picture is due to reduced contractility

The stroke volume is low because of tachycardia which is causing insufficient filling time during diastole

The PVR is approximately 170 dynes

The SVR = 1707 dynes The SV is approximately 22 ml/beat

Explanation / Answer

Normal hemodynamic parameters:

Based on above data

1st Statement is True (A)

2nd statement is False (B) that should be increased

3rd statement is also False (B) that should be decreased

4th Statement is True (A) reduced strike volume causes the effects

5th statement is also False (B       ) that should be increased
