===Altitude decompression sickness===
{{further|Decompression (altitude)}}

Treatment and management may vary depending on the grade or form of decompression sickness and the treating facility or organization. First aid at altitude is oxygen at the highest practicable concentration and earliest and largest practicable reduction in cabin altitude.

Ground-level 100% oxygen therapy is suggested for 2 hours following type-1 decompression sickness that occurs at altitude, if it resolves upon descent. In more severe cases, hyperbaric oxygen therapy following standard recompression protocols is indicated. Decompression sickness in aviation most commonly follows flights in non-pressurized aircraft, flights with cabin pressure fluctuations, or in individuals who fly after diving. Cases have also been reported after the use of altitude chambers. These are relatively rare clinical events.<ref name="Statpearls" />
