Emergency airway management in orbit: an evidence-based review of possibilities

It is likely that the first responder to a medical emergency in space will be a nonphysician. Terrestrial experience has shown that even under optimal conditions experienced clinicians can have difficulty establishing an airway. Establishing and maintaining a patent airway is essential to ensuring a successful outcome from cardiopulmonary resuscitation or respiratory failure secondary to trauma or acute illness. A patent airway is required to provide a pathway for ventilation and oxygenation. For minimally trained care providers the airway will also be the first route of administration of resuscitative pharmacologic agents. It is therefore of paramount importance that the method for securing and airway permit a successful outcome when used by nonphysician crewmembers during medical emergencies in space. This article evaluates airway management in the microgravity environment and applies to both the International Space Station and the Space Shuttle, whether operating independently or docked.
