UH-60 NRCM Questions With Complete Solutions
Hypoxia
state of O2 deficiency in the blood cells and tissues significant
enough to cause impairment of function
Stages of Hypoxia
Indifferent ( 0 to 10,000 feet)
Compensatory (10,000 to 15,000 ft)
Disturbance (15,000 to 20,000 ft)
Critical ( 20,000 ft and above)
Types of Hypoxia
Hypoxic
Hypemic
Histotoxic
Stagnant
Hypoxic Hypoxia
not enough oxygen in the atmosphere, low atmospheric pressure
prevents diffusion of oxygen
Hypemic Hypoxia
reduction in oxygen carrying capacity of blood
Histotoxic Hypoxia
metabolic poisons such as cyanide prevent the tissues from
using oxygen delivered to them
Stagnant Hypoxia
,circulation is inadequate
Dysbarism
Various manifestations of gas expansion induced by decreased
barometric pressure (Trapped Gas Disorder, Evolved Gas
Disorder)
Trapped Gas Disorder
When expanding gas cannot escape places such as the teeth,
sinuses, middle ear, gastrointestinal (GI) tract
Evolved Gas Disorder
When atmospheric pressure is reduced because of an increase in
altitude, gases dissolved in body fluids at sea-level are released
and become a gas
Valsalva Maneuver
Close the mouth, pinch the nose shut, tilt your head upwards and
blow firmly
Never attempt Valsalva during ascent
