What does thinner air mean?

- Which is in a condition of rarefaction, that is, of reduced density: the air r. of the high mountains; in the specific sense, of gases at a pressure lower than the normal atmospheric one: rarefied gases. ... [of air, which is in a condition of reduced density: the rarefied air of the high mountains] ≈ fine, light, thin. ↔ heavy.

How do you breathe at 3000 meters?

humidity of the air. The partial pressure of oxygen in the air passes from about 160 mmHg at sea level to about 110 mmHg at 3000 m, bringing the oxygen saturation in the blood from 98% to 90%.

How does atmospheric pressure vary as altitude increases?

Atmospheric pressure varies with altitude. Atmospheric pressure decreases with increasing altitude as the height of the air column above the earth's surface decreases and the density of the air decreases.

How much oxygen is there at 3000 meters?

The partial pressure of oxygen in the air passes from about 160 mmHg at sea level to about 110 mmHg at 3000 m, bringing the oxygen saturation in the blood from 98% to 90%.

How do you breathe at 5.000 meters?

At 5000 meters the values ​​of atmospheric pressure and partial pressure of oxygen are respectively: 405 and 84,9 mmHg. At the top of Mount Everest the atmospheric pressure is 236,3 mmHg with a partial pressure of oxygen equal to 49,5 mmHg.
