Question
What is the alveolar ventilation of a patient who is breathing 15 times per minute and has a dead space volume of 300 mL and a tidal volume of 500 mL?
Solution
Alveolar ventilation refers to the amount of fresh air that reaches the alveoli per minute. It can be calculated using the formula:
Alveolar Ventilation = (Tidal Volume - Dead Space Volume) * Breathing Rate
Given in the question:
Tidal Volume (TV) = 500 mL Dead Space Volume (DSV) = 300 mL Breathing Rate (BR) = 15 breaths per minute
Substitute these values into the formula:
Alveolar Ventilation = (500 mL - 300 mL) * 15 breaths per minute Alveolar Ventilation = 200 mL/breath * 15 breaths per minute Alveolar Ventilation = 3000 mL/minute
So, the alveolar ventilation of the patient is 3000 mL/minute.
