Flight Paramedic Exam Questions and AnswersBoyle's Law (Balloon=Barotrauma - Answer- The pressure a gas is inversely proportional to the volume of a gas at a constant temperature.
IV drip rates increase, affects ETT cuffs
Dalton's Law "Dalton's Gang" - Answer- Law of partial Pressures. Responsible for soft tissue swelling at altitude
Charles' Law
"Charging Charles" - Answer- At a constant pressure, the volume of gas is directly proportional to the absolute temperature of a gas. As you charge O2 tank, the tank gets hot
Gay Lussac's Law - Answer- Direct relationship between temperature and pressure.
ex: car tires in cold weather.
Graham's Law
Grey Matter - Answer- Law of Gaseous Diffusion
Gas exchange at cellular level
Henry's Law
Heineken - Answer- Solubility of a gas in a liquid
the BENDS
Bends Ground transport is preferred - Answer- Type 1 Nitrogen related, painful joints mottled skin, pruritus; "ants are crawling on their Skin"
Cutis Marmorata- Mottled Skin, can look like a sunburn
Type 2 Neurologic s/s hypovolemic Shock
Arterial Gas Embolism - Answer- Boyle's Law
breathe holding during ascent on a dive. causes pnuemo. air can be forced into blood stream creating air bubble blocks. Hyperbaric Chamber! fly in aircraft under 10k Mean Sea Level
Pulmonary Overpressurization - Answer- POP; Boyle's law
greatest pressure difference <4 ft
inexperienced divers can cause pneumo or mediastinal emphysema
atmosphere - Answer- Sea Level = 1 ATM = 760 Torr
33ft = 2 ATM 66ft = 3 ATA
Physiologic Zone - Answer- sea level to 10,000 feet
Night Vision is decreases at 5000ft MSL
Physiologic Deficient Zone
TUC=Time of useful Consciousness - Answer- 10K to 50K ft MSL
O2 pressurization is required
Sign of compression loss is cooler temperature and window fogging. Normally 90 Sec TUC at 30000ft If a rapid decompression occurs TUC is @45 Sec
Pressure Values - Answer- Sea level = 760 Torr = 1 ATM
10K = 523 Torr
18K = 380 Torr = 1/2 ATM
Hypemic Hypoxia - Answer- -Reduction in oxygen carrying capacity of the blood.
-Anemia, blood loss
histotoxic hypoxia - Answer- Limits available 02 due to poisoning of the cytochrome oxidase system
Cyanide, Alcohol, Carbon Monoxide, Nitroglycerin, Sodium Nitroprusside
Hypoxic - Answer- Decrease partial pressure of oxygen at altitude
Deficiency in Alveolar 02 exchange
Cardiovascular/Pnuemo pts are more susceptible
Stagnant Hypoxia - Answer- Reduction in blood flow; e.g. positive G maneuvers
Cardiogenic Shock
Stages of Hypoxia (ICDC) - Answer- Indifferent: Full reasoning, some loss of night vision
Compensatory: Increased HR Ventilations, Slowed Judgement
Disturbance: Slurred Speech, impaired judgement, "drunk" Critical: No longer able to physiologically function, death immenent
G forces affects - Answer- Decrease Blood Pressure
effect people: B/P meds (beta Blockers), dehydrated, hyperglycemic meds
