Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main study objective was the arterial oxygenation after 30 min of exposure with each of the tested devices or after room air at 2650 m. Oxygenation was evaluated by blood gases from the arterialised ear lobe (PaO2, partial oxygen pressure). | — |
Secondary
| Measure | Time frame |
|---|---|
| Oxygen saturation (SaO2) was measured by pulse oxymetrie after 30 min of exposure with one of the tested devices or with room air at 2650 m. Carbon dioxide partial pressure (PaCO2) was assessed together with the primary outcome (PaO2) by arterial blood gas measurement. | — |
