Abstract
Changes in arterial O2 saturation during exercise were measured with a new 8-wavelength ear oximeter and calculated from blood gas measurements on simultaneously drawn arterial blood samples from 48 patients with pulmonary diseases. When the calculated O2 saturation during exercise was more than 80% there was a fair correlation between the measured and calculated exercise-induced change in O2 saturation. This non-invasive, simple and rapid method seems to be clinically useful for detecting the development of significant arterial hypoxemia during exercise in patients with pulmonary diseases.
