ANSWER.
* Calculation of cardiac output.
Formula
Cardiac output (CO) = Stroke volume(SV) * Heart rate(HR)
Here
Stroke volume(SV) = 110 ml/min.
Heart rate(HR) = 102 bpm.
As per above formula
Cardiac output = 110 * 102
= 11220 ml/min.
Convert ml to l by multiply dividing with 1000
So
Cardiac output = 11220/1000
= 11.22 l/min.
A = 11 liters/min.

Case 1- New data set: ABP: 90/60 mm Hg, HR 145 beats/min, cardiac output=3 l/min, CVP=0 mm Hg, PAP=30/10 mm Hg, PCWP=2 mm Hg. I calculated that MAP=70 mm Hg, SVR=1866.7 dynes, PA mea=16.7 mm HG, PVR=139.2 dynes, and SV=20.1 ml. I just need help with the conceptual questions: A. How would SV normally respond if venous return increases? (increase, decrease, or nothing) B. What would be the best treatment for the patient? (diuretics, aortic balloon pump, intravenous fluid admin,...
