Comparative StudyComparison of the FiO2 delivered by seven models of the self-inflating bag-mask system.
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 O2 fractions delivered by seven resuscitators receiving different O2 flows. ⋯ All resuscitators capable of being connected to an O2 reservoir delivered a higher O2 concentration when connected to this device. Resuscitators that do not have this capability delivered a higher O2 concentration than the ones that could be connected to this device but are used without it.
