Types of Hypoxia


HYPOXIA


The state of Oxygen deficiency in the tissues sufficient to cause impairment of function.


THE SIGNS AND SYMPTOMS OF HYPOXIA


Hypoxia can affect people in different ways. Learning how to spot the signs in others and recognize your symptoms is an important way to combat hypoxia. How it affects you is largely determined by your overall health, lifestyle, alcohol or drug use, medications, fitness and stress.


Signs - Others may notice some signs of your hypoxia long before you do. Noticeable signs may include:


• Hyperventilation • Slurred speech • Loss of coordination • Loss of concentration • Poor judgment • Slow decision making • Sleepiness or nodding off • Belligerence or short tempered • Tremors • Cyanosis - Blue lips, fingernail beds

Air hunger Apprehension Fatigue Nausea Headache Dizziness Denial


Hot & Cold Flashes Euphoria Belligerence Blurred vision Numbness Tingling extremities


Preventive hypoxia countermeasures: • Fly at an altitude where oxygen is not required • Fly in a pressurized cabin


• Fly in accordance with the regulations on the use of supplemental oxygen


TREATMENT


The treatment for hypoxia is oxygen. Remember to slow your breathing to reduce the chance of hyperventilation. Along with oxygen, descend the aircraft to increase the available pressure. Recovery from hypoxia happens very quickly after the administration of oxygen.
