Preventative measures and acclimatisation strategies

Treatment and management of AMS
Descent: Priority action to reduce altitude. Oxygen: Supplemental oxygen for symptom relief. Hydration: Ensure adequate fluid intake. Rest: Avoid further ascent until symptoms resolve. Medications: Use under guidance, such as dexamethasone.
