Clinical Trial Summary

This project aims to test the accuracy of pulse oximeters in the range of arterial HbO2 saturations from 100% down to 70%.

Description:

This project aims to test the accuracy of pulse oximeters in the range of arterial HbO2 saturations from 100% down to 70%. This is done by comparing the pulse oximeter reading during brief, steady state hypoxia plateaus with a gold-standard measurement of blood oxyhaemoglobin saturation.
