This would actually be a simple answer: Pressure decreases.
Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
Air pressure is always greater nearer the earth surface than at altitude due to the mass of air above.
the temperature decreases as you increase in altitude.
The atmospheric pressure reduces
intrapleural pressure exceeds atmospheric pressure, but lungs don't collapse because intra-alveolar pressure increases, too (4 mmHg pressure gradient stays same)
atmospheric
as altitude rises less there is less atmospheric pressure
As altitude above seal level increases, atmospheric pressure decreases.
Air pressure is always greater nearer the earth surface than at altitude due to the mass of air above.
If performed correctly, your altitude should increase.
If performed correctly, your altitude should increase.
Think of the air pressure on any horizontal surface as the weight of all the air above it, all the way to the top of the atmosphere. As you increase altitude (go higher, on a mountain or in an airplane), there is steadily less atmosphere above you, and the air pressure steadily decreases with altitude.
If performed correctly, your altitude should increase.
If performed correctly, your altitude should increase.
If performed correctly, your altitude should increase.
The rate of change of air pressure as a function of increasing altitude decreases with increasing altitude.

it decreases
