High-intensity intermittent exercise increases pulmonary interstitial edema at altitude but not at simulated altitude.

Objective: Ascent to high altitude leads to a reduction in ambient pressure and a subsequent fall in available oxygen. The resulting hypoxia can lead to elevated pulmonary artery (PA) pressure, capillary stress, and an increase in interstitial fluid. This fluid can be assessed on lung ultrasound (LUS) by the presence of B-lines.

Comparison of factors associated with desaturation in prehospital emergency anaesthesia in primary and secondary retrievals.

Objective: To investigate the incidence and factors associated with desaturation related to emergency intubations within an aeromedical retrieval service pertaining to both primary prehospital and secondary interhospital missions.

Methods: A retrospective analysis of all rapid sequence intubations (RSI) was performed by the Emergency Medical Retrieval Service over a 4.5-year period (June 2008-November 2012).
