Summary
Performance testing of pulse oximeters. The protocol involves brief stable arterial oxygen desaturation in healthy volunteers and sampling arterial blood when a stable level of hypoxia has been attained. The blood sample is analyzed for oxygen saturation with a gold standard bench CO-oximeter. This protocol is aligned with the latest ISO and FDA guidance documents for pulse oximeter testing.
