What is the minute ventilation of a person who takes a breath every 5 seconds and has a tidal volume of 500 mL?

A. 600 mL/min
B. 420 mL/min
C. 2500 mL/min
D. 6000 mL/min
E. 4200 mL/min

Answer :

The minute ventilation of a person who takes a breath every 5 seconds and has a tidal volume of 500 mL is: d. 6000 mL/min.

  • The minute ventilation of a person who takes a breath every 5 seconds and has a tidal volume of 500 mL can be calculated as follows:

Minute Ventilation = Tidal Volume x Respiratory Rate x 60

  • Given: Tidal Volume = 500 mL, Respiratory Rate = 5 seconds per breath

Minute Ventilation = 500 mL x (60 seconds / 5 seconds) x 60

Minute Ventilation = 6000 mL/min
