Calculate the stroke volume (SV) and the stroke volume index (SI) using the following infor-mation: cardiac output = 4.5 L/min, heart rate = 110 beats/min, and body surface area = 1.3 m2
a. SV = 41 mL; SI = 31.5 mL/m2
b. SV = 45 mL; SI = 34.3 mL/m2
c. SV = 46 mL; SI = 36 mL/m2
d. SV = 49.5 mL; SI = 38 mL/m2
ANS: A
Stroke volume (SV) = cardiac output (C.O.)/heart rate (HR) and stroke index (SI) = stroke vol-ume (SV)/body surface area (BSA)
