Question

Quizplus · Accepted Answer

The oxygen cost of breathing in healthy individuals averages from 0.5 to 1.0 ml of oxygen per liter of ventilation. Given a normal minute ventilation of 5 L/min, the oxygen cost of breathing would be 2.5 to 5 ml out of a total oxygen consumption of 250 ml/min. This represents less than 5% of the oxygen consumption of the body.
