Brief summary

Pulse oximeters are used in many areas of clinical medicine and a clear understanding of their performance is critical to appropriate and safe use. This study aims to evaluate the accuracy of a new pulse oximeter under a range of oxygen conditions compared with CO-ocimetry, which is the current reference method for this measurement.

Interventions

Subjects are acutely exposed to a range of hypoxic gas mixtures to induce falls in arterial oxygen saturation in the range 95-70%. Oximeter readings (SpO2) are compared with simultaneously determined CO-oximetry measurements of SaO2 from arterial blood samples. These samples are drawn once a steady state has been achieved at each level of hypoxaemia, usually 3-5 minutes.
