Abstract

The resuscitator bag has been considered the standard for prehospital, ventilatory managment. Recently, the Berg Resuscitation Apparatus (BRA) was developed as an alternative. Two devices were compared for their ability to deliver adequate tidal volumes and efficacy during simulated, single-rescuer CPR In the first phase, emergency care providers ventilated a test lung using a resuscitator bag, BRA, and demand valve. No significant differences between methods were found. During the second phase of the study, subjects performed single-rescuer CPR on a resuscitation mannikin for two minutes, using the bag-valve-mask and the BRA with a mask. The BRA delivered a volume of 0.81±0.26 liters compared to 0.35±0.19 liters using the resuscitator bag. The BRA allows ventilation to be performed as does the traditional equipment. When used in single rescuer CPR, it appears to provide a substantial increase in the tidal volumes delivered.
