Devices for expired air resuscitation.

OBJECTIVES: Expired air resuscitation is an essential part of first-aid and cannot be replaced by other measures. Because of the risk of transmitting infectious diseases, the use of devices is recommended. Three types are available--masks, tubes, and foils. PARTICIPANTS: Six masks (Air-Vita Bi-Protect, Laerdal Pocketmask, Dräger Hivita Mask E, Rescue-Med Device, Resuscitator, SealEasy Resuscitation Kit), five tube instruments (Dr. Brook Airway, Dual-Aid, Goettinger Tubus, Lifeway, Sussex Valve Airway), and two foils (Ambu Life-Key, Laerdal ResusciFace Shield) were studied. MEASUREMENTS: Inspiratory and expiratory resistance, valve leakage, ability to protect against infection transmission, and practicability (e.g., possibility of training on standard mannequins, seal) were measured and tested in the laboratory. RESULTS: Only a few of the mask and tube devices had low inspiratory and expiratory resistances. Some of the one-way valves failed. There were definite risks of provoking complications (vomiting, lacerations) when using tube instruments. CONCLUSIONS: Devices consisting of a foil have definite advantages, and seem to be more appropriate for the use by first-aiders [first responders].
