Describe hypoxia.

Description should include the following concepts:

• Hypoxia means reduced or not enough oxygen.
• Common symptoms of hypoxia include visual impairment, unconsciousness, lightheaded or dizzy sensation, tingling sensations, hot and cold sensations, and muscle spasms.
• Although any tissue will die if deprived of oxygen long enough, the greatest concern regarding hypoxia during flight is lack of oxygen to the brain, since it is particularly vulnerable to oxygen deprivation.
• Any reduction in mental function while flying can result in life-threatening errors.
• Hypoxia can be caused by several factors, including an insufficient supply of oxygen, inadequate transportation of oxygen, or the inability of the body tissues to use oxygen.
• Factors that contribute to hypoxia include age, altitude, smoking/vaping, and chronic conditions.
