RESUMO

The performance of seven marks of autoinflated resuscitator bag manufactured and/or commercialized in Brazil was studied using a lung-test and an analyzer analogical about: FiO2 offered for O2 flow received, O2 flow offered without manipulation of the compressible unit, patient valve lock-up when resuscitator receives na O2 flow of 35 l/min, patient valve backward leakage, drop test, inspiratory and expiratory flow resistance, valve function after contamination by vomitus, easy cleaning and information contained in the device. The resuscitators that possess the option for attached the reservoir of O2 had supplied to a best concentration of FiO2 with this accessory. The resuscitator that does not have the option of attached of the reservoir of O2 had presented greater offers of O2 flow without the manipulation of the compressible unit. The resuscitator that receive O2 flow from in the interior of the compressible unit, had the valve of the patient fixed when they had received O2 flow higher than 5 l/min, modifying the peak pressure, the tidal volume and inspiratory and expiratory flow. The resuscitator when used as source of offering O2 flow without the manipulation of the compressible unit must be with reservoir of O2 connected and receiving 15 l/min of O2. Three resuscitators receiving 35 l/min had been disabled to ventilate the lung test because patient valve lock-up. One resuctitator presented imperfection in the patient valve backward leakage. The highest resistance to the inspiratory flow had been of 7 and 8 cmH2O and the highest resistance to the expiratory flow was of 7 cmH2O. All resuctitators had passed in the test of valve function after contamination by vomitus and drop test. Any resuctitators offered information about to the flow of safe O2 to the compressible unit and the offered FiO2. The different models of resuctitators can get different performances.
