Abstract: BACKGROUND AND OBJECTIVES: Since resuscitators with self-inflating bag-mask systems manufactured and/or commercialized in Brazil are widely available and used in health services, both out- and intra-hospitals, the objective of this study was to determine the O 2 fractions delivered by seven resuscitators receiving different O 2 flows. METHODS: Seven resuscitators with self-inflating bag-mask systems were tested at the Respiratory Unit of the HC/UNICAMP. A wall O 2 flowmeter was connected to the resuscitator that received an O 2 flow of 1, 5, 10, and 15 L.min -1 and those were connected to a test lung. Resuscitators capable of being connected to an O 2 reservoir were tested with and without this accessory. Twenty consecutive measurements were performed and the mean determined. RESULTS: Only one resuscitator delivered and O 2 fraction slightly below the accepted limit (0.80) when used with the O 2 reservoir. Without this device, all resuscitators achieved the minimal limit of O 2 fraction (0.40). Resuscitators not capable of being connected to an O 2 reservoir delivered a higher O 2. CONCLUSIONS: All resuscitators capable of being connected to an O 2 reservoir delivered a higher O 2 concentration when connected to this device. Resuscitators that do not have this capability delivered a higher O 2 concentration than the ones that could be connected to this device but are used without it. © Sociedade Brasileira de Anestesiologia, 2009.
