Evaluation of manually operated self-inflating resuscitation bags
Abstract:
Eight resuscitators were tested, of which five have recently been improved by the manufacturers (Air Shields Ambu, Danish-made Ambu, Pulmonator, Laerdal Resusci II, and Air Viva). One had an addition made to improve its oxygen (O2)-delivering capacity (Hope bag fitted with Blount collar) and two were new, the Air Bird, with and without high O2-concentration delivering system. The first five resuscitators were all in some way an improvement over their earlier counterparts. However, some still malfunction, some do not deliver adequate O2 concentrations for hospital use, and there is still a great variability in their performance. In some, freezing at low temperatures or clogging of valves with mucus are special hazards.
