Automated titration, as well as the SpO2 target, may have an impact on oxygen utilization, with potential logistical effects in emergency and military transportation.

We sought to assess the oxygen flow required for different SpO2 targets in spontaneously breathing subjects, and to evaluate individualized automated oxygen titration to maintain stable oxygenation in subjects with COPD and healthy subjects with induced hypoxemia.

 In the first part of the study, oxygen flow was evaluated in hospitalized subjects for different SpO2 targets from 90% to 98%.

Oxygen requirements to reach these targets were determined using a device that automatically adjusts oxygen flow every second on the basis of the SpO2 target.

In the second part of the study, the same automated oxygen titration method was used to correct hypoxemia in subjects with COPD and in healthy subjects with induced hypoxemia while the subjects wore a gas mask.

Oxygen flow, SpO2, and heart rate were continuously recorded.
