beats/min, arterial pressure is 120/70 mm Hg, arterial hematocrit is 35%, and body temperature is normal. His pressure-volume diagram for the left ventricle is shown. What event occurs at point B on the man's pressurevolume diagram?
A. A-V valves close
B. Aortic valve opens
C. Aortic valve closes
D. A-V valves open
E. Third heart sound
Homework Answers
Ans (c)Aortic valve closes
The mitral valve closes. Since pressure is also lower than the aortic pressure, the aortic valve is closed as well
Add Answer to:
beats/min, arterial pressure is 120/70 mm Hg, arterial
hematocrit is 35%, and body temperature is normal....

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,...
