Question

For individuals ascending from low altitude, the first stage of all staged ascent protocols should be ≥ __ d of residence at moderate altitude.

Answer 1

The first stage of all staged ascent protocols should be a minimum of 3 days of residence at moderate altitude to help the body acclimatize.

Step-by-step explanation:

In individuals ascending from low altitude, the first stage of all staged ascent protocols should be a minimum of 3 days of residence at moderate altitude.

Residence at moderate altitude helps the body acclimatize and adjust to the lower oxygen levels at higher altitudes, reducing the risk of altitude sickness. This gradual ascent allows the body to produce more red blood cells and increase oxygen-carrying capacity.

For example, a hiker walking up a mountain gradually from low altitude to the first overnight hut, spending a few days there before ascending further, would follow a staged ascent protocol.
