Questions and Answers

What is the classical explanation for worsening hypercapnia in patients with chronic CO2 retention exposed to high levels of inspired oxygen?

Stimulation of hypoxic drive to breathe

Suppression of hypoxic drive to breathe (correct)

Increased hypoxic drive to breathe

Enhanced hypercapnic drive

What is an important cause of hypoxemia in patients with COPD?

Increased alveolar ventilation

Ventilation–perfusion mismatch (correct)

Enhanced oxygen diffusion

Decreased perfusion mismatch

What happens to ventilation–perfusion (Va/Q) ratio when PaO2 is increased through supplemental oxygen administration?

It remains unchanged

It decreases due to abolished hypoxic pulmonary vasoconstriction (HPV) (correct)

It increases due to enhanced hypoxic pulmonary vasoconstriction (HPV)

It fluctuates randomly

What effect does increased perfusion have on better ventilated alveolar units in COPD patients receiving supplemental oxygen?

What happens to the gradient for CO2 when alveolar oxygen diffusion is enhanced through supplemental oxygen administration?
