Q: What are some Major equipment and meds needed to run AMT?
Answer:
RSI Kit, Airway supplies, Oxygen, Drugs for cardiac episodes, Intubation, sedation, steroids,
Analgesics and for a suction unit. Must have IV pumps with tubing BMV’s, Monitors for vitals
and gases, and a stretcher. May have to do in flight tracheostomy or intubation.
Q: What are effects of altitude during flight on the human body.
Answer:
Decreased partial pressure of O2. Pb changes, decreased humidity, Volume expansion, Thermal
changes, Gastric distinction, Noise, vibration, fatigue, G force, These things can make it difficult
to fly.
Q: What is Boyles law and why is it important to flight?
Answer:
Pressure and volume are inversely related at a constant temperature. Gas in the human body and
in the equipment will expand depending on the altitude of the flight. Trapped air in certain
locations like the belly, ears , sinus and ETT cuff is common. Monitor is needed.
Q: What to do if O2 drops during the flight.
Answer:
Administer O2 , monitor breathing , check ETT pressure if incubated, as well as other
equipment, If nothing brings the O2 up bring the chopper to lower altitude
Q: What are some common signs of hypoxia
Answer:
ALOC , headache, blurred vision, and Dyspnea complains with increased WOB
Q: What happens to the stomach and GI tract during flight? Why does it occur
Answer:
The stomach and GI trac expand with the increase in saturated volume. This volume causes the
diaphragm to have pressure exerted on it which can have respiratory consequences.
Q: What happens to the ear pressure with a change in pressure and altitude
Answer:
When ear gas expands can block the ear off until cleared. Clearing happens by chewing,
Vasalvagal maneuver, yawning, or swallowing
Q: How does increased altitude effect humidity
Answer:
As air cools humidity Is lost. So temperature and humidity go down with increase in ATM. Can
lead to dehydration
Dehydration can lead to… dry sore throat , nasal passages, sputum viscosity, chapped lips, dry
mouth and hoarseness.; This can also lead tp respiratory issues if continued long enough
Q: What are some significant side effects of lack of humidity in the atmosphere?
