Oxygen Delivery Performance of Four Adult Resuscitation Bags*
Published online by Cambridge University Press: 28 June 2012
Extract
The Vitalograph bag resuscitator with the old and new reservoirs, the PMR 1, the PMR 2, and the Laerdal bag resuscitator were studied at various oxygen flowrates and ventilation patterns, with and without oxygen reservoirs, to determine fractional delivered oxygen (FDO2) and function of patient valves. The Vitalograph with the new or the old reservoir and the PMR 1 cannot deliver high oxygen concentrations (FDO2 > 0.90) and should not be used when high FDO2 is important. The PMR 2 and the Laerdal cannot deliver high oxygen concentrations without a reservoir attached; but with a reservoir and oxygen flowrates of 101/min the Laerdal does achieve FDO2 > 0.98, and at 15 1/min the PMR 2 does achieve > 0.90.
