, Flight Physiology & Environment (50 questions)
1. A flight crew is transporting a patient at 8,000 feet cabin altitude. The patient has a closed
head injury. Which physiological change is of greatest concern?
A. Cerebral edema due to decreased barometric pressure
B. Increased intracranial pressure due to hypoxia
C. Decreased cerebral perfusion due to hyperventilation
D. Seizure activity due to altitude-induced alkalosis
✓ Correct answer: A. Cerebral edema due to decreased barometric pressure
Rationale: At altitude, decreased barometric pressure leads to gas expansion and decreased partial
pressure of oxygen. In patients with closed head injury, this can exacerbate cerebral edema and
increase intracranial pressure. The combination of hypoxia and gas expansion creates a dangerous
environment for brain-injured patients. Hypoxia alone is also a concern, but the gas expansion effect
on cerebral edema is the primary concern in closed head injury at altitude.
Why the others are wrong:
B: Hypoxia is a concern, but the gas expansion effect is more directly related to altitude changes.
C: Hyperventilation is a compensatory response but is not the primary concern.
D: Altitude-induced alkalosis is not the primary concern in head injury.

Guidelines · FAA Regulations.
2. A patient on a ventilator is being transported by air. The flight crew notices the ventilator
is alarming with high pressure. What is the most likely cause?
A. Gas expansion in the endotracheal tube cuff
B. Increased airway resistance due to altitude
C. Decreased oxygen concentration at altitude
D. Ventilator malfunction due to pressure changes
✓ Correct answer: A. Gas expansion in the endotracheal tube cuff
Rationale: As altitude increases, barometric pressure decreases, causing gas expansion. The air in the
endotracheal tube cuff expands, increasing cuff pressure and potentially compressing the trachea,
leading to high pressure alarms. This is a well-known phenomenon in air transport. The crew should
monitor cuff pressure and deflate as needed. Increased airway resistance, decreased oxygen
concentration, and ventilator malfunction are less likely causes.
Why the others are wrong:
B: Airway resistance is not directly affected by altitude.
C: Oxygen concentration is a concern but does not cause high pressure alarms.
D: Ventilator malfunction is less likely than gas expansion.

Guidelines · FAA Regulations.
,3. Which of the following is the primary cause of hypoxia at altitude during air transport?
A. Decreased barometric pressure reducing oxygen partial pressure
B. Decreased oxygen concentration in the cabin
C. Increased carbon dioxide levels in the cabin
D. Decreased hemoglobin oxygen affinity
✓ Correct answer: A. Decreased barometric pressure reducing oxygen partial pressure
Rationale: At altitude, the primary cause of hypoxia is the decreased barometric pressure, which
reduces the partial pressure of inspired oxygen. The oxygen concentration (FiO2) remains
approximately 21% at altitude, but the partial pressure of oxygen decreases with decreasing barometric
pressure. This is the fundamental physiological challenge of altitude flight. Cabin pressurization helps
mitigate this, but decompression or unpressurized flight can cause significant hypoxia.
Why the others are wrong:
B: Oxygen concentration in the cabin remains approximately 21%.
C: Carbon dioxide levels are not the primary cause of hypoxia.
D: Hemoglobin oxygen affinity changes are secondary to the reduced partial pressure.

Guidelines · FAA Regulations.
4. A patient with a pneumothorax is being transported by air. What is the most significant
risk during flight?
A. Tension pneumothorax due to gas expansion
B. Decreased oxygen saturation due to altitude
C. Increased pain due to barotrauma
D. Air embolism due to pressure changes
✓ Correct answer: A. Tension pneumothorax due to gas expansion
Rationale: The most significant risk for a patient with a pneumothorax during air transport is the
development of a tension pneumothorax. As the aircraft climbs, the trapped air in the pleural space
expands due to decreased barometric pressure, potentially causing a tension pneumothorax. This is a
life-threatening emergency. The crew should place a chest tube or needle decompression kit readily
available. Decreased oxygen saturation, pain, and air embolism are also concerns but are secondary to
the tension pneumothorax risk.
Why the others are wrong:
B: Oxygen saturation is a concern but not the most significant risk.
C: Pain from barotrauma is a concern but not life-threatening.
D: Air embolism is a risk but less common than tension pneumothorax.

Guidelines · FAA Regulations.
, 5. A flight crew is preparing to transport a patient with a tracheostomy. Which action is most
important to prevent complications during flight?
A. Ensure the tracheostomy cuff is filled with air and monitor cuff pressure
B. Deflate the tracheostomy cuff to prevent pressure injury
C. Replace the tracheostomy tube with a smaller size
D. Place a spare tracheostomy tube at the bedside
✓ Correct answer: A. Ensure the tracheostomy cuff is filled with air and monitor cuff pressure
Rationale: During air transport, the tracheostomy cuff must be properly inflated and cuff pressure
monitored. As altitude changes, gas expansion can increase cuff pressure, potentially causing tracheal
injury or compromising the airway. The cuff should be filled with air (not saline) and pressure should
be monitored. Deflating the cuff would risk aspiration. Replacing the tube is not necessary. Having a
spare tube is important but not the most important preventive action.
Why the others are wrong:
B: Deflating the cuff would increase the risk of aspiration.
C: Replacing the tube is not necessary.
D: Having a spare tube is important but not the most important action.

Guidelines · FAA Regulations.
6. A patient on vasopressors is being transported by air. What is the most important
consideration regarding the vasopressor infusion?
A. The infusion pump may malfunction due to altitude changes
B. The vasopressor may degrade due to temperature changes
C. The vasopressor may have increased potency at altitude
D. The vasopressor may cause arrhythmias at altitude
✓ Correct answer: A. The infusion pump may malfunction due to altitude changes
Rationale: Infusion pumps can malfunction or deliver inaccurate rates at altitude due to changes in
barometric pressure and viscosity of fluids. The crew should use pumps that are approved for air
transport or use manual infusion methods. The vasopressor itself does not degrade due to temperature
changes in typical flight conditions. Potency does not increase at altitude. Arrhythmias are a known
side effect but are not specific to altitude.
Why the others are wrong:
B: Temperature changes in the cabin are not significant enough to degrade vasopressors.
C: Potency does not increase at altitude.
D: Arrhythmias are a known side effect but are not specific to altitude.
