Overview
Research interests include the study of cardiorespiratory function in humans during challenging clinical settings including the perioperative period, and exposure to environmental conditions such as diving and high altitude. Studies have included gas exchange during diving, the pathophysiology of high altitude and immersion pulmonary edema, the effect of anesthesia and postoperative analgesia on pulmonary function and monitoring of tissue oxygenation. Ongoing human studies include the effect of respiratory muscle training on chemosensitivity and blood gases during stressful breathing: underwater exercise.

Journal Article Commun Med (Lond) · December 19, 2024 BACKGROUND: Oxygen-rich breathing mixtures up to 100% are used in some underwater diving operations for several reasons. Breathing elevated oxygen partial pressures (PO2) increases the risk of developing central nervous system oxygen toxicity (CNS-OT) whic ...
