Background:We evaluated six different pediatric manual resuscitation bags. The bags usedwere made by Ambu, Rusch (2), Pulmonex, Baxter and Allegiance. The researchwas conducted in order to determine function and the fractional delivered oxygenconcentration (FDO2) with a 100% O2 sourceand to determine function with varying tidal volume delivery.

Methodology:The oxygen was given via a calibrated flowmeter at 15L/min and measured witha Hudson-RCI 5590 calibrated analyzer for every trial according to ASTM F-920and ISO 8382 which specify an outcome of FDO2 of >or = to 85% with attachments and > or = to 40% without attachments for eachdevice. Four 6-minute trials for every bag were conducted with a lung simulator.Two of the trials were done with a tidal volume (VT) of 150 mL andthe other two trials used a VT of 400 mL. Each trial was done withand without an oxygen reservoir system. Rate and I:E ratio were checked viaa stopwatch and chronometer.

Results:The use of a reservoir system increased the FDO2 of thebag and decreased the time required for the bags to reach a higher FDO2.Results from 1-6 minutes varied from 79% to 100% at a tidal volume of 150 mLwith a reservoir, and from 88% to 100% at a tidal volume of 400 mL with a reservoir.Results from 1-6 minutes varied from 42% to 79% at a tidal volume of 150 mLwithout a reservoir, and from 40% to 57% at a tidal volume of 400 mL withouta reservoir (see figure).

Experience: Therapists should be aware that a higher FDO2 canbe delivered with a reservoir and larger tidal volume as opposed to a smallertidal volume and that devices may require 4-5 minutes to achieve their MaximumFDO2.

Conclusions:Devices should be independently tested to secure the best device for the pediatricpatient independent of cost.
