What is the immediate treatment for altitude pulmonary edema?

The immediate treatment for altitude pulmonary edema involves moving to a lower altitude. This condition occurs when fluid builds up in the lungs due to high elevations, which can significantly impair oxygen exchange and lead to serious respiratory difficulties. Descending to a lower altitude alleviates the pressure differences that cause fluid accumulation, allowing for better breathing and improved oxygenation.

While the other options, like applying ice or providing pain medication, do not address the underlying issue of altitude sickness and may even delay appropriate treatment, the critical action is to descend. Staying hydrated and resting can be supportive measures but are not sufficient in managing the acute symptoms of altitude pulmonary edema. Moving to a lower altitude is essential for recovery and reintegration into a higher altitude environment safely.
