As of May 2021, at least 11 mountaineers have died on Mount Everest during the spring climbing season. This has been one of the deadliest seasons in recent years, with several deaths attributed to overcrowding, exhaustion, and altitude sickness. The high number of fatalities has raised concerns about the safety and management of climbing on the world's highest peak. **

This can lead to symptoms of altitude sickness, such as dizziness, fatigue, and shortness of breath. Using an oxygen device helps to supplement the body's oxygen levels, reducing the risk of altitude sickness and allowing the mountaineer to continue climbing safely. **
