Flight Physiology & Aviation Regulations
1. Which of the following gas laws explains why an air-filled endotracheal tube cuff
expands during flight ascent?
• A) Dalton's Law
• B) Boyle's Law
• C) Henry's Law
• D) Charles's Law
Answer: B) Boyle's Law
Rationale: Boyle's Law states that gas volume is inversely proportional to pressure. As
an aircraft ascends, ambient pressure drops, causing trapped air inside the ET tube cuff
to expand.
2. A patient experiences worsening hypoxemia at high altitudes due to a decrease in the
partial pressure of oxygen, despite the fractional concentration of oxygen (FiO2)
remaining at 21%. Which gas law describes this?
• A) Dalton's Law
• B) Graham's Law
• C) Henry's Law
• D) Boyle's Law
Answer: A) Dalton's Law
Rationale: Dalton's Law states that the total pressure of a gas mixture is the sum of
the partial pressures of its individual gases. At altitude, barometric pressure decreases,
lowering the partial pressure of oxygen (PO2) and driving hypoxia.
3. Decompression sickness ("the bends") occurs when nitrogen gas bubbles come out of
solution in the blood due to a rapid drop in ambient pressure. Which gas law governs
this process?
• A) Charles's Law
• B) Boyle's Law
• C) Henry's Law
, • D) Gay-Lussac's Law
Answer: C) Henry's Law
Rationale: Henry's Law states that the amount of gas dissolved in a liquid is
proportional to the partial pressure of that gas over the liquid. Rapid ascent drops the
pressure, forcing dissolved nitrogen out of blood solution into bubbles.
4. Which Federal Aviation Regulation (FAR) specifically governs general operating and flight
rules for non-commercial, general aviation flights?
• A) FAR Part 121
• B) FAR Part 135
• C) FAR Part 91
• D) FAR Part 145
Answer: C) FAR Part 91
Rationale: FAR Part 91 dictates general aviation rules for non-commercial flights.
Medical transport flights operating without a patient on board or not flying for hire
frequently fall under Part 91.
5. When an air medical helicopter is actively transporting a patient for hire, under which
Federal Aviation Regulation must the flight operate?
• A) FAR Part 91
• B) FAR Part 135
• C) FAR Part 121
• D) FAR Part 119
Answer: B) FAR Part 135
Rationale: FAR Part 135 mandates strict commercial operational rules for commuter
and on-demand flight operations, which includes active air medical transport with a
patient on board.
Advanced Airway Management & Ventilation
6. While transport-ventilating a patient with a severe fat embolism, the patient develops
worsening shunting and hypoxia. What ventilator adjustment is most appropriate to
recruit alveoli and improve oxygenation?
• A) Increase the respiratory rate
• B) Decrease the tidal volume
