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.
对八台复苏器进行了测试，其中五台最近由制造商进行了改进（Air Shields Ambu、丹麦制造的Ambu、Pulmonator、Laerdal Resusci II和Air Viva）。有一台增加了装置以提高其氧气输送能力（配备布朗特颈圈的霍普袋），还有两台是新型的，即带和不带高氧浓度输送系统的Air Bird。前五台复苏器在某种程度上都比其早期型号有所改进。然而，有些仍会出现故障，有些无法提供医院使用所需的足够氧浓度，而且它们的性能仍存在很大差异。在一些复苏器中，低温冻结或阀门被黏液堵塞是特殊的风险。
