Quick Answer
Descend immediately if symptoms persist or worsen after treatment with rest, hydration, and medication, such as acetazolamide, and you experience severe headache, nausea, vomiting, or shortness of breath.
Recognizing the Need to Descend
When experiencing altitude sickness, the first priority is to recognize the severity of your symptoms. If you’re at an altitude above 8,000 feet (2,438 meters) and experience any of the following, it’s time to descend: headache, nausea, vomiting, fatigue, or shortness of breath. Monitor your body’s response to treatments like rest, hydration, and medication. If symptoms persist or worsen, it’s crucial to descend.
Assessing the Risk of Descent
Before descending, assess the risks involved. If you’re in a remote area with limited access to medical care, it’s essential to prioritize your safety. Consider factors like weather conditions, terrain difficulty, and the availability of transportation. In general, it’s best to descend 1,000 to 2,000 feet (305 to 610 meters) in the first 24 hours to alleviate symptoms.
Techniques for Safe Descent
When descending, pace yourself to avoid exacerbating symptoms. Take regular breaks to rest and rehydrate. Aim to descend at a rate of 500 to 1,000 feet (152 to 305 meters) per day. Consider using oxygen therapy if available, especially if you’re experiencing severe symptoms. If you’re in a group, stay together and monitor each other’s condition.
