Question

Question 84 Based on the following data collected at rest select the most plausible physiological values from the options presented. All options can only be used once LV End diastolic volume 160ml LV End systolic volume 70ml SA node discharge rate 60/min BP 140/70 Cardiac Output at rest (L) # Ejection fraction at rest (%) # Stroke Volume at rest (ml) # HR at rest (bpm) # HR following vagal stimulation (bpm) A. 90 B. 5.4 C. 80 D. 70 E. 93 F. 60 G.56 H. 210 l. 40 J. 65 Pulse pressure at rest (mmHg) Mean arterial pressure at rest (mmHg) Systolic BP at 80% VO2max (mmHg) Diastolic BP at 80% VO2max (mmHg) SV at rest following dehyrdation (ml) # -

Explanation / Answer

Cardiac output at rest is B. 5.4 L/min

Ejection fraction at rest is G. 56%

Stroke volume at rest is C 80ml

HR at rest is F. 60

Pulse pressure at rest is D. 70mmHg

Mean arterial pressure at rest is SBP+2(DBP)/3= E. 93mmHg

Systolic BP at 80%VO2 max is H. 210mmHg

Diastolic BP 80%VO2 max is A. 90mmHg

SV at rest following dehydration is I. 40ml
