Question

(CO)=SV*HR is the formula used to calculate the volume of blood pumped out per minute.which of the following is the value of (CO)in a normal adult​

Answer 1

Answer:

Cardiac output (CO) is the product of the heart rate (HR), i.e. the number of heartbeats per minute (bpm), and the stroke volume (SV), which is the volume of blood pumped from the ventricle per beat; thus, CO = HR × SV. Values for cardiac output are usually denoted as L/min.

Answer 2

The value of CO for a normal adult is 5-6 Litres.

• Cardiac output refers to the amount of blood pumped by ventricles during very contraction.
• Cardiac output is measured in terms of $\frac{milliliters}{minute}$.
• It is the product of Heart rate x Stroke volume.
• Heart rate is the number of times the heart beats in a minute. It is 75 beats per minute.
• Stroke volume is the amount of blood pumped by each ventricle in each beat. It is 70 millilitres per minute.
• Therfore,

                       Cardiac output =SV x HR

                                                 =75 x 70

                                                 ≈ (approx 5 Litres)

• The value of CO for a normal adult is 5-6 Litres.
