Effective Performance Times should always be a consideration.
At 25,000 feet, the maximum altitude of the Cirrus, the time of useful consciousness is about 3-5 minutes.
It is extremely important to continually monitor the oxygen system at be prepared to deal immediately with any oxygen malfunction.
Hot & Cold Flashes
Increase in rate and depth of breathing
Loss of muscle coordination
Rate of Ascent
Duration of Exposure
Rate of DecompressionFactors influencing hypoxia
15,000 MSL:Crew must use Oxygen, and must be provided to each occupant
14,000 MSL:Crew must use Oxygen for flights duration
12,500 MSL:Crew must use Oxygen after 30 min
Results in exhaling too much Carbon Dioxide.
Cold, clammy skin
Return Rate and Depth of Breathing to Normal
Paper Bag Method
Used at altitude where supplemental oxygen is not required or needed
Talk or sing to control the rate of breathing.Treatment for Hyperventilation
The eustachian tube allows air pressure to equalize in the middle ear.
