Randomized Controlled Trial Comparative StudyRespiratory function in hoist rescue: comparing slings, stretcher, and rescue basket.
Some types of equipment used in helicopter hoist rescue have the potential to cause respiratory embarrassment due to chest compression and/or body positioning. This study compared the respiratory effects of four commonly used devices. ⋯ The RB was not associated with any change in measured outcomes. Other methods tested, especially SSling, have detrimental effects on respiratory function.

Evaluation of a novel basic life support method in simulated microgravity.
If a cardiac arrest occurs in microgravity, current emergency protocols aim to treat patients via a medical restraint system within 2-4 min. It is vital that crewmembers have the ability to perform single-person cardiopulmonary resuscitation (CPR) during this period, allowing time for advanced life support to be deployed. The efficacy of the Evetts-Russomano (ER) method has been tested in 22 s of microgravity in a parabolic flight and has shown that external chest compressions (ECC) and mouth-to-mouth ventilation are possible. ⋯ The ER method can provide adequate depth and rate of ECC in simulated microgravity for 3 min to allow time to deploy a medical restraint system. There is, however, a physiological cost associated with it and a need to use the flexion of the arms to compensate for the lack of weight.
