The esophageal detector device: a rapid and accurate method for assessing tracheal versus esophageal intubation in a porcine model.

Study Objectives: To assess time and accuracy of the esophageal detector device (EDD), disposable end-tidal CO2 monitor (ETCO2), and standard clinical methods for detection of endotracheal tube placement.

Design: Prospective, randomized, single-blinded, controlled laboratory investigation.

Methods: Thirty airway managers (physicians, nurse anesthetists, and paramedics) used one pig (Sus scrofa) as the intubated, respiratory depressed/arrest model.

Altitude symptomatology and mood states during a climb to 3,630 meters.

Ascents to altitudes above 3,050 m have been shown to cause adverse changes in symptoms and moods. The severity of these changes may depend not only on the altitude and rate of climb, but also on the length of stay and the effort expended to reach the desired altitude. In order to better understand how these factors influence symptom and mood changes during a climb, this study systematically assessed symptoms and moods during an ascent to 3,630 m.

Dexamethasone for prevention and treatment of acute mountain sickness.

We wished to determine in a field study the effectiveness of dexamethasone for prevention and treatment of acute mountain sickness (AMS). Prevention Trial: We transported 15 subjects from sea level to 4,400 m (PB = 400 mm Hg) on Denali (Mt. McKinley) by means of a 1-h helicopter flight.
