Flight Paramedic Questions And Answers
Graham's Law
Grey Matter Law of Gaseous Diffusion
Gas exchange at cellular level
Henry's Law
Heineken Solubility of a gas in a liquid
the BENDS
Bends Ground transport is preferred 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 Boyle's Law
, Flight Paramedic Questions And Answers
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 POP; Boyle's law
greatest pressure difference <4 ft
inexperienced divers can cause pneumo or mediastinal emphysema
atmosphere Sea Level = 1 ATM = 760 Torr
33ft = 2 ATM
66ft = 3 ATA
Physiologic Zone sea level to 10,000 feet
Night Vision is decreases at 5000ft MSL
Physiologic Deficient Zone
, Flight Paramedic Questions And Answers
TUC=Time of useful Consciousness 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 Sea level = 760 Torr = 1 ATM
10K = 523 Torr
18K = 380 Torr = 1/2 ATM
Hypemic Hypoxia -Reduction in oxygen carrying capacity of the blood.
-Anemia, blood loss
histotoxic hypoxia Limits available 02 due to poisoning of the cytochrome oxidase system
Cyanide, Alcohol, Carbon Monoxide, Nitroglycerin, Sodium Nitroprusside
Hypoxic Decrease partial pressure of oxygen at altitude
Deficiency in Alveolar 02 exchange
, Flight Paramedic Questions And Answers
Cardiovascular/Pnuemo pts are more susceptible
Stagnant Hypoxia Reduction in blood flow; e.g. positive G maneuvers
Cardiogenic Shock
Stages of Hypoxia (ICDC) 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 Decrease Blood Pressure
effect people: B/P meds (beta Blockers), dehydrated, hyperglycemic meds
