Acute mountain sickness is not repeatable across two 12-hour normobaric hypoxia exposures.
The purposes of this experiment were to determine the repeatability of acute mountain sickness (AMS), AMS symptoms, and physiological responses across 2 identical hypoxic exposures. ⋯ The LLS was not repeatable across 2 identical hypoxic exposures. Increased familiarity with the environment (not acclimation) could explain the reduced AMS severity on the second hypoxic exposure. Headache was the most reliable AMS symptom.

Long-term complications of rattlesnake bites: a telephone survey from Central California.
The purpose of this institutional review board-approved, cross-sectional study was to identify residual symptoms and signs of envenomation reported by snakebite survivors via a telephone survey. ⋯ Our study population demonstrated a notable incidence (43%) of self-reported persistent symptoms related to their rattlesnake bites, although the overall level of disability from these injuries seems low.

Case ReportsMechanical chest compressions in an avalanche victim with cardiac arrest: an option for extreme mountain rescue operations.
Mountain rescue operations often present helicopter emergency medical service crews with unique challenges. One of the most challenging problems is the prehospital care of cardiac arrest patients during evacuation and transport. In this paper we outline a case in which we successfully performed a cardiopulmonary resuscitation of an avalanche victim. A mechanical chest-compression device proved to be a good way of minimizing hands-off time and providing high-quality chest compressions while the patient was evacuated from the site of the accident.

Evaluation of fluid bolus administration rates using ruggedized field intravenous systems.
The purpose of this study was to evaluate 2 ruggedized field intravenous (IV) systems currently in use by US military medics and to determine their effect on fluid bolus administration rates. ⋯ Ruggedized field IV systems can significantly delay fluid bolus rates. In instances where ruggedized field systems are deemed necessary, pressure infusion devices should be considered to overcome the constrictive effects of the ruggedized system.
