At what elevation has HAPE been reported in high-risk patients?

High-Altitude Pulmonary Edema (HAPE) is a serious condition that can occur in individuals who ascend to high elevations without proper acclimatization. It is particularly dangerous for high-risk patients, such as those with pre-existing health conditions or those who rapidly ascend to high altitudes.

Evidence indicates that HAPE typically develops at elevations around 8,000 feet or higher, but reported cases in high-risk individuals have specifically been noted at elevations around 5,000 feet. This elevation is significant because it is where the body begins to experience the challenges associated with reduced oxygen availability, leading to symptoms that can escalate into more severe conditions like HAPE.

Understanding this information is critical, especially for search and rescue operations in mountainous areas, as rescuers need to be aware of the risks associated with high altitude and how to manage patients who may be impacted. This knowledge helps in planning safe ascents and avoiding situations where HAPE could occur.
