Flight Physiology, Safety survival and CAMTS Flashcards
Inital intervention for managing a patient presenting with bariobariatrauma is
Administer high flow O2 by NRB 15 min prior to lift off
What is bariobariatrauma
Overweight perosns are more susceptible to evolved gas decompression sickness as fatty tissue contains more nitrogen
What is the Bends
Pain in and around the joints and can become progressively worse during ascent
What is The Chokes
Pain in the chest caused by blocking of smaller pulmonary blood vessels by innumerable small bubbles. In severe casaes there is a sensation of suffocation
Which gas law is described by inversely proportional relationship between the absolute pressure and volume of a gas if the temp is constant within a closed system ex, air in a ETT cuff expands upon ascent and contracts during descent
Boyles law
Which gas law is described by the rates of movement of gasses at the same temp and pressure are inversely proportional to the square root of its molecular mass
Grahms Law
Which gas law is described by the total pressure of a gas mixture is the sum of the individual or partial pressure of all the gases in the mixture
Daltons Law
Which gas law is described by the law of volumes states that for an ideal gas at constant pressure, the volume is proportional to the absolute temp, which describes how gases tend to expand when heated
Charles Law
Which gas law is described by A sample of a gass at a constant volume is directly proportional to its temp, ex if a gas temp decreses, then so does its pressure
Gay-lussac Law
A flight suit should only fit to allow how much of air space between the suit and undergarments
.25 inch
Define Sterile cockpit
Prohibits nonessential communications between crew and pilot during critical phases of flight
What should be the only thing taken from the aircraft after a crash
survial kit
A patient recieving O2 at 2 lpm becomes hypoxic during flight what do you do any why
Turn up O2,
The patient sufferred hypoxic Hypoxia due to the high altitude and low barometric pressure. There is a fdeficiency in the alveolar oxygen exchange which interfers with gas exhange in ventilation and diffusion.
What classic sign of hypoxia is an unrelialbe sign
Cyanosis, this is a late sign of hypoxia, 75% SpO2
An increase in altitude produces what environmental conditions
low humidity and low temp
What do you do if the pilot is incapasatated after a crash
Turn off throttle fuel and then battery
No pilot may take off or land an aircraft uner Visual Flight Rules when the report ceiling or visibility less than
day
night
500ft and 1 mile
1,000 and 1 mile
What is the emergency airband frequencies
121.5MHz and 243.0 MGz
Time of Useful Consiousness
30,000 90sec
35,000 30-60sec
>40,000 <15 sec
At what altitude does night vision loss occur
5,000ft
What condition occurs when patient area exposed to light that flicker at a rate of 4-20 cycles per seconds causing nasuea and vomiting and in severe cases, seizures
Flicker Vertigo
What is the first course of action after a hard landing in an aircraft that has filled with smoke
Exit only after aircraft has come to a complete stop and the rotors have stopped
How much time should there be between comunications while in flight
15 minutes during flight
30 minutes on ground transport
What is the time minimum for the pilots bottle to throttle time
8 hours
Who has the final authority in flight related issues of the nonmedical aspets of flight
PIC pilot in command
What can a flight member do to prevent heat loss after capsizing in water
HELP heat eascape lessening posture
knees to chest and arms across the chest
What must be proven to prove malpractice
causation, injury, damages
What radio signal follows the curvature of the earth and has the greatest range
VHF low band
How many G’s does it take to activate the ELT
4
You may fly __ in __ but you cannt fly __ in __
You may fly IFR in VFR but you cannot fly VFR in IFR
What is the number one cause of aero-medical crash
Pushing the weather
What are the four basic variables that affect gas volumetric relationships
Temp, Pressure, and relative mass of the gas
How many live intubations must one have before flying according to CAMTS
5
During an inflight emergency what should be done
turn off o2, helmet visors in the down position and all equipment must be secured
What are the requirements for Helipads acording to CAMTS
perimeter lighting, fence around helipad, have a device to identifiy wind direction and velocity, must have two approach paths, fire suppresion equiptment,
What is the leading cause of death in scuba divers
AGE arterial gas embolism
Identify the stressors of flight
decrese Partial pressure of O2
barometric pressure changes
thermal changes
decreased humidity
noise, vibration, fatigue, G forces
