Unrelated to altitude and at a constant pressure (atm) there is a proportional relationship between the temperature and volume of a gas.
Charles Law
For each 1k ft of ascent temperature decreases by ____ *C.
2
When altitude increases, air pressure decreases, causing any gas in the body or equipment to expand.
Boyle’s Law
1 ATM is = to ____ mmHg
760
P1V1=P2V2
Boyle’s Law Equation
In flights which problem relating to Boyle’s law is the only Decent problem in contrast to all other problems occurring on ascent?
Barotitis Media
Nitrogen Narcosis resulting from affinity of nitrogen to adipose tissue. Morbidly obese patients. Treatment: O2 will increase partial pressure and cause nitrogen to diffuse. Start prior to flight. (Boyle’s law)
Barobaria Trauma
Air trapped in dental space. (boyle’s law)
barodontalgia
At a given mass and constant volume of gas the exerted pressure on the sides of it’s container is directly proportional to it’s absolute temperature. (Not PSI, refers to exertional pressure of gas within a container)
Gay-Lussac’s Law
Law of partial pressure’s

Critical
At this stage of hypoxia SPO2 is approximately 70-80% (15-20k’)
Disturbance
At this stage of hypoxia SPO2 is approximately 80-90% (10-15k’)
Compensatory
At this stage of hypoxia SPO2 is approximately 90-98% (0-10k’)
