  • Evaluation of bag-valve-mask ventilation by paramedics in simulated chemical, biological, radiological, or nuclear environments.
    The described model allowed a reproducible and reliable measurement of the delivered minute ventilation . All paramedics were able to operate the device without prior CBRN training. The maximum minute volume achieved without the filter was 9.5 +/-2.7 l/min. Use of the inlet CBRN filtration system reduced the maximum minute volume to 6.3 +/-2 … The inherent breathing resistance of the CBRN filter appears to reduce the inflow of air into the self-inflatable bag.
