------------------------------------------------ If a person's tidal volume is 3000 mL and their respiratory rate is 10 breaths per minute, what is their minute ventilation?

A. 30 L/minute
B. 300 mL/minute
C. 3 minutes/L

The minute ventilation, calculated as the product of tidal volume and respiratory rate, for a person with a tidal volume of 3000 mL and 10 breaths per minute is 30 L/min. Therefore, the correct answer to the question is: a. 30 L / minute

The question pertains to the calculation of minute ventilation, which is a product of the tidal volume and the respiratory rate. Minute ventilation is the amount of air exhaled in one minute of breathing.

To calculate minute ventilation:

Tidal Volume (VT): 3000 mL (or 3.0 L)

Respiratory Rate: 10 breaths per minute

Minute Ventilation = Tidal Volume x Respiratory Rate

Minute Ventilation = 3000 mL/breath x 10 breaths/min = 30000 mL/min or 30 L/min

Therefore, the minute ventilation for a person with a tidal volume of 3000 mL and a respiratory rate of 10 breaths per minute is 30 L/min.
