Abstract
To evaluate the performance characteristics of disposable bag-valve resuscitators. Single and multitrial tests under simulated clinical conditions. Results of multitrial tests were analyzed by multivariate analysis of variance. A pulmonary laboratory in a university hospital. We evaluated eight DRs to determine: a) physical characteristics, including the potential for misassembly; b) FIO2 of 1.0 and flow rates of 10 L; c) tidal volume (VT) (male and female operators) using one and two hands; and d) cycling rates at 5°, 20°, and 48°C. All resuscitators met the minimum requirements of the Canadian Standards Association and the American Society for Testing and Materials. However, the CPR and LSP could be assembled incorrectly for use. Three units (B Sav, Pulm, and MPR) delivered significantly Conclusion While these DRs meet the minimum standards, they should be chosen carefully and evaluated before application in the clinical environment.
