Table 2

Adverse events that can occur during patient transport [8] from the ICU to MRI (adapted from Day).

Category	Adverse event
Airway	(i) Loss
	(ii) Acute obstruction
Breathing	(i) Respiratory arrest
	(ii) Hypoxemia, decreased PaO2/FiO2 ratio
	(iii) Ventilator-associated pneumonia
	(iv) Tension pneumothorax
Circulation	(i) Cardiac arrest
	(ii) Hemodynamic instability
	(iii) Bleeding
	(iv) Air embolus
Disability (neurological)	(i) Increased intracranial pressure
	(ii) Spinal cord injury destabilization

FiO₂, fraction of inspired oxygen; ICU, intensive care unit; MRI, magnetic resonance imaging; PaO₂, partial pressure of oxygen in the arterial blood.
