BACKGROUND: Postobstructive pulmonary edema (POPE)-also referred to as negative pressure pulmonary edema-occurs with deep inspiration against a closed glottis or obstructed airway. The result can be life threatening, however, most cases have a self-limited presentation and resolve with supportive care.
OBJECTIVE: Our aim was to critically evaluate a previously unreported mechanism in the exacerbation of POPE.
CASE REPORT: This is a report of a 50-year-old woman who experienced an acute episode of hypoxia and altered mental status aboard a transcontinental flight. Her presentation was suggestive of pulmonary embolus. However, a detailed history yielded an episode of preflight choking relieved by the Heimlich maneuver. After 2 days of supportive care she was discharged with a complete return to baseline.
CONCLUSIONS: Subclinical cases of POPE can be exacerbated by the low atmospheric pressure experienced on commercial airlines. With early recognition and supportive treatment, the patient returned to baseline before her discharge 2 days later. Making the diagnoses of POPE is not always straightforward for the practitioner and necessitates a broad differential. Initial supportive care focusing on maximizing respiratory support is critical.
