Flashcards in Stages of Hypoxia Deck (11):
0 - 10,000ft
Loss of night vission as low as 5,000ft.
10,000 - 15,000
Physiological compensations provide some defense against hypoxia
May be some increase in depth of RR and rate, HR and CO
15,000 - 20,000
In this stage the physiological compensations do not provide adequate oxygen for the tissues.
may include fatigue, exhaustion, drowsiness, dizziness, headache, breathlessness, and euphoria.
In the critical stage consciousness is lost. Death follows shortly.
Time of useful consciousness 20,000ft
Time of useful consciousness 25,000ft
3 - 5 MIN
Time of useful consciousness 35,000ft
< 1 MIN
Time of useful consciousness 45,000ft
10 - 15 SEC
Suplamental oxygen and rapid desent below 10,000ft
what factors put you at risk for hypoxia
(D.E.A.T.H) Drugs, Alcohol, Exhaustion, Tabaco, Hypoglycemia.
