A man’s pulse rate is 68 and cardiac output is 5500 cm3. Find the stroke volume. |
|
Answer» Cardiac output is the volume of blood pumped out per min for a normal adult human being it is calculated as follows: Cardiac output = Heart rate × Stroke volume Given : Cardiac output = 5500 cm³ Pulse rate = Heart rate = 68 By using these values stroke volume of is calculated as follows: ∴ Cardiac output = Heart rate × Stroke volume ∴ Stroke volume = Cardiac output/Heart rate = 5500/68 = Approx. 80. ∴ Stroke volume is 80 ml. |
