HEALTH EFFECTS OF LACK OF PROPER BLEED AIR SYSTEMS

Rapid decreases in air pressure cause air inside the middle ear

and sinuses to escape the body in an attempt to equalise with the surrounding environment - usually experienced as a popping sensation.

Sustained low pressure can lead air to escape too forcefully and cause headaches, stomach pain and bleeding from the nose and ears.

In healthy individuals, there may be a slight elevation in the rate of heartbeat and breathing and some fatigue.

The brain is particularly sensitive to hypoxia (a condition in which the body or a part of the body is deprived of adequate oxygen supply). Thus, the ability to think and act can become seriously impaired.
