G-forces review (FW only). Altitude chamber orientation or ROBD orientation. Altitude chamber or ROBD practical exercise. What are the four atmospheres of the Earth? ✔✔Troposphere, Stratosphere, Mesosphere, and Thermosphere The negative effects of bubbles formed from undissolved N2 in the body is known as ✔✔Decompression Sickness (DCS) Atmospheric pressure _____ with increasing altitude ✔✔decreases What altitude levels does the efficient zone include? ✔✔MSL to 10,000 feet What altitude levels does the deficient zone include? ✔✔10,000 feet - 50,000 feet What altitude levels does the space equivalent zone include? ✔✔50,000 feet and upward Without the use of supplemental O2, a decrease in night vision capabilities occurs above what altitude? ✔✔4,000 feet Decompression sickness is rare below what altitude? ✔✔18,000 feet The higher the pH level of the blood is the more (acidic/basic) and O2 (deprived/rich) it is. ✔✔Basic, Rich The lower the blood pH level is, the more (basic /acidic) and O2 (rich/deprived) it is. ✔✔Acidic, Deprived Increased CO2 in the blood leads to _______ blood levels. ✔✔acidic Decreased CO2 in the blood leads to _______ blood levels. ✔✔basic/alkaline Define Hypoxic Hypoxia ✔✔Not enough O2 in the air or decreasing atmospheric pressure prevents diffusion of O2 from the lungs to the bloodstream. Define Hypemic, or anemic, hypoxia ✔✔A reduction in the blood's O2 -carrying capacity. (Common in carbon monoxide poisoning) Define Stagnant Hypoxia ✔✔A reduction in the circulation of blood (due to compressed blood vessels) What is histotoxic hypoxia? ✔✔results from an interference of body tissues to use oxygen (alcohol, narcotics, cyanide interfere with cell's ability to use an adequate supply of oxygen) Usually occurs from: alcohol abuse, drugs, poisons. Cyanide can cause histotoxic hypoxia. What are subjective signs and symptoms of hypoxia? ✔✔Increased breathing rate, apprehension, fatigue, headache, euphoria, blurred vision, dizziness What are objecti ve signs and symptoms of hypoxia? ✔✔hyperventilation, cyanosis, mental confusion, poor judgment, lack of muscle coordination What are the physiological effects of smoking cigarettes concerning flight? ✔✔Loss of about 20% of a smoker's night vision at sea level and a physiological altitude of 5,000 feet at sea level. What are the physiological effects of alcohol concerning flight? ✔✔Creates condition for histotoxic hypoxia. 1 oz. of alcohol can have a physiologic altitude of 2000 feet sea level. What are the four stages of hypoxia? ✔✔Indifferent Compensatory Disturbance Critical At what altitude does indifferent hypoxia occur? ✔✔0-10,000 feet
