Arterial hypoxemia does not stimulate ventilation until PO2 reaches which level?

A normal 80 kg man is breathing at a rate of 17 with a tidal volume of 600 ml. By estimation, what is his approximate alveolar ventilation?

What is the arterial oxygen content of an individual who has a PaO2 of 300 mmHg, oxygen saturation of 99%, and hemoglobin of 16 g.

Which of the following explains the rapid, shallow breathing strategy of patients with pulmonary fibrosis?

Which is the correct formula to calculate the alveolar minute ventilation of a spontaneously breathing subject?

All of the following conditions stimulate the chemoreceptors, except:

Saturation percent is a measure of oxygen or hemoglobin concentration. In other words, 100% saturation automatically implies that the blood oxygen content is normal.

What is the most common cause of resting hypoxemia?

Which of the following conditions produce stimulation of the J-receptors?

Stimulation of which of the following receptors explains the stimulation of ventilation after splashing cold water on the skin?
