Quick Answer
To help someone experiencing altitude illness, descend to a lower elevation if possible, and provide rest, hydration, and acetazolamide (Diamox) if prescribed. Monitor for symptoms and seek medical attention if they worsen or persist.
Recognizing Altitude Illness Symptoms
Altitude illness can manifest in different ways, including Acute Mountain Sickness (AMS), High-Altitude Pulmonary Edema (HAPE), and High-Altitude Cerebral Edema (HACE). Monitor for symptoms such as headaches, fatigue, nausea, dizziness, and shortness of breath. If you notice any of these symptoms, especially in individuals who ascend rapidly or to high elevations, seek immediate medical attention.
Acclimatization Techniques
To prevent altitude illness, acclimatization is key. Plan to ascend to higher elevations gradually, allowing the body time to adapt. Aim to ascend no more than 1,000 feet (305 meters) per day, with an overnight stay at the intermediate elevation. This allows the body to adjust to the lower oxygen levels and reduces the risk of altitude illness.
Treating Altitude Illness
If you suspect someone has altitude illness, descend to a lower elevation as quickly and safely as possible. Administer acetazolamide (Diamox) if prescribed, and provide rest and hydration. Monitor symptoms closely, and seek medical attention if they worsen or persist. In severe cases, hospitalization may be necessary. Always carry a portable altitude meter and know the nearest medical facility in case of an emergency.
