Supplemental oxygen
Oxygen delivered by nasal cannula or mask at flow rates sufficient to achieve an SpO2 >90% provides a suitable alternative to descent, particularly when patients can access healthcare facilities and be closely monitored.91e93 As noted earlier in the section on AMS/HACE treatment, providers should target an SpO2 of >90% rather than a particular FIO2. Short-term use in the form of visits to oxygen bars or use of over-the-counter oxygen canisters has no role in HAPE treatment. Recommendation. When available, supplemental oxygen sufficient achieve an SpO2 of >90% or to relieve symptoms should be used while waiting to initiate descent when descent is infeasible and during descent in severely ill patients. Recommendation Grade: 1A
