-
Hypoxic Hypoxia
"Not enough oxygen in the air"
Deficiency in alveolar O2 exchange
-
Histotoxic Hypoxia
"Poisoning"
Limits use of available oxygen due to a toxin.
(Cyanide, Alcohol, Nitroglycerin, Sodium Nitroprusside, Viagra)
-
Stagnant Hypoxia
"Blood isn't moving"
- Reduced cardiac output or pooling of blood
- (High G-forces *take off*, cardiogenic shock)
-
Hypemic Hypoxia
"Anemic"
- Reduction in the O2 carrying capacity of blood
- (Anemia, Hemorrhage, Carbon Monoxide)
-
Indifferent Stage of Hypoxia
Full reasoning abilities
-
Compensatory Stage of Hypoxia
Increased HR, ventilations, slowed judgement
-
Disturbance Stage of Hypoxia
Slurred Speech, Impaired Judgement, "Drunk"
-
Critical Stage of Hypoxia
No longer able to physiologically function - death imminent.
