Calculate the aveolar ventilation based on the following information: Tidal volume 500 mls anatomical dead air space 100 mls, residual volume 1,200 mls, respiration rate 20 breaths per minute.

Answer 1

To calculate the alveolar ventilation, we need to subtract the dead space volume from the tidal volume and then multiply by the respiratory rate.

Tidal volume - Dead space volume = Alveolar ventilation

500 mL - 100 mL = 400 mL

Alveolar ventilation = 400 mL * 20 breaths/minute = 8,000 mL/minute

Therefore, the alveolar ventilation is 8,000 mL/minute.
