,1. A patient with a severe traumatic brain injury (TBI) is being transported by
helicopter at an altitude of 8,000 feet. The flight team notes a sudden rise in
intracranial pressure (ICP). Which combination of altitude-related physiological
changes most directly contributes to this rise?
A. Decreased arterial oxygen tension and increased cerebral blood flow due to hypoxic
vasodilation
B. Increased venous return and decreased cerebrospinal fluid absorption
C. Decreased barometric pressure causing expansion of intracranial air and increased
cerebral edema
D. Increased heart rate and blood pressure leading to cerebral hyperperfusion
Answer: A. Decreased arterial oxygen tension and increased cerebral blood flow
due to hypoxic vasodilation
At altitude, decreased barometric pressure reduces arterial oxygen tension (PaO2).
Hypoxia triggers cerebral vasodilation to increase oxygen delivery, which elevates
cerebral blood volume and ICP. Options B, C, and D are less direct: C (intracranial air
expansion occurs but is less immediate), B (venous return changes are minimal), D
(hyperperfusion from hypertension is not the primary altitude effect).
2. A 75 kg patient on a mechanical ventilator is being transported in a fixed-wing
aircraft cruising at 35,000 feet. The cabin is pressurized to 8,000 feet. The ventilator
is set to deliver a tidal volume of 500 mL at a rate of 12 breaths/min. At altitude,
which of the following best describes the change in delivered tidal volume if the
ventilator is volume-controlled but not altitude-compensated?
A. Decreased due to increased gas density
B. Increased due to reduced gas density and decreased resistance to flow
C. Unchanged because the ventilator delivers a fixed volume
D. Decreased due to expansion of gas within the ventilator circuit
Answer: B. Increased due to reduced gas density and decreased resistance to flow
At altitude, lower atmospheric pressure reduces gas density, lowering resistance to flow
in the ventilator circuit. In a volume-controlled ventilator, the same piston or bellows
displacement delivers a larger volume of gas (as measured at ambient pressure) because
the gas expands. This can cause overdistention. Option A is incorrect because density
decreases. Option C is false because volume-controlled ventilators deliver a fixed
volume at ambient conditions, not corrected to sea level. Option D is incorrect;
expansion occurs in the patient's lungs, not circuit loss.

,3. During a scene flight to a motor vehicle collision, the flight crew encounters a
patient with suspected tension pneumothorax after needle decompression. The
patient remains hypotensive and hypoxic. Which of the following actions should the
crew prioritize next, considering the unique challenges of the prehospital air medical
environment?
A. Perform a second needle decompression in the same interspace
B. Insert a chest tube using sterile technique
C. Increase the ventilator rate to improve oxygenation
D. Administer a bolus of 500 mL of isotonic crystalloid
Answer: B. Insert a chest tube using sterile technique
In a patient with tension pneumothorax who remains unstable after needle
decompression, definitive chest tube placement is indicated. Air medical crews are
trained to perform tube thoracostomy. Option A is ineffective if the first attempt failed;
a different site may be needed but chest tube is more definitive. Option C (increasing
rate) does not address the pneumothorax. Option D (fluid bolus) may temporize but
does not treat the cause. The air medical environment requires definitive intervention
before transport.
4. A patient with ST-elevation myocardial infarction (STEMI) is being transported
from a rural hospital to a percutaneous coronary intervention (PCI) center. The
flight time is 45 minutes. The patient has a blood pressure of 90/60 mm Hg and heart
rate of 110 bpm. Which of the following pharmacological interventions is most
appropriate to support coronary perfusion during transport?
A. Administer a 500 mL normal saline bolus and start a dopamine infusion at 5 mcg/kg/min
B. Start a norepinephrine infusion titrated to maintain mean arterial pressure (MAP) > 65
mm Hg
C. Administer nitroglycerin intravenously at 10 mcg/min and monitor for hypotension
D. Start an epinephrine infusion at 0.1 mcg/kg/min
Answer: B. Start a norepinephrine infusion titrated to maintain mean arterial
pressure (MAP) > 65 mm Hg
In cardiogenic shock from STEMI, norepinephrine is the vasopressor of choice to
maintain MAP and coronary perfusion without excessive tachycardia. Option A
(dopamine) is associated with more arrhythmias and is inferior to norepinephrine.
Option C (nitroglycerin) would worsen hypotension. Option D (epinephrine) may
increase myocardial oxygen demand and arrhythmia risk. Norepinephrine provides
balanced vasoconstriction and inotropy.

, 5. A flight team is called to transport a patient with a suspected pulmonary
embolism (PE) who is hemodynamically unstable. The referring facility has already
administered a bolus of unfractionated heparin. During transport, the patient
becomes increasingly hypoxic and hypotensive. Which intervention should the team
consider as a bridge to definitive care?
A. Administer a second bolus of heparin
B. Start a dopamine infusion
C. Prepare for thrombolytic therapy with alteplase
D. Increase the fraction of inspired oxygen to 100% and place the patient in Trendelenburg
position
Answer: C. Prepare for thrombolytic therapy with alteplase
In massive PE with hemodynamic instability, thrombolysis is indicated even if heparin
has been given. The risk of bleeding is outweighed by the need to reduce clot burden.
Option A (repeat heparin) does not lyse existing clot. Option B (dopamine) does not
address the obstruction. Option D (Trendelenburg) may worsen ventilation-perfusion
mismatch. Alteplase is the standard fibrinolytic for PE.
6. A patient with a subarachnoid hemorrhage (SAH) is being transported for
endovascular coiling. The flight team notes a decline in the patient's level of
consciousness. Which of the following altitude-related factors is most likely to
exacerbate cerebral vasospasm in this patient?
A. Hypocapnia from hyperventilation due to anxiety
B. Hypoxia-induced cerebral vasodilation
C. Decreased partial pressure of oxygen leading to increased cerebral blood flow
D. Increased sympathetic outflow causing hypertension
Answer: A. Hypocapnia from hyperventilation due to anxiety
In SAH, cerebral vasospasm is a major complication. Hypocapnia (low PaCO2) causes
cerebral vasoconstriction, which can worsen vasospasm and reduce cerebral blood flow.
Anxiety and hyperventilation during flight can induce hypocapnia. Options B and C
(hypoxia-induced vasodilation) would theoretically improve blood flow, not exacerbate
vasospasm. Option D (hypertension) is often induced to maintain perfusion, not
exacerbate vasospasm.
