Abstract

<p>Purpose and method：1）We measured the transition of oxygen concentration in vinyl lungs of a mannequin when ventilated using a pocket face mask (pocket mask) while supplying 100% oxygen via an oxygen inlet. The experiment was subsequently repeated using a bag valve mask (BVM). 2）Rescue breathing was performed using a pocket mask, and the transfer of bacteria from the oral cavity into the lungs was measured. Results：1）After 180 seconds long insufflation, the mean oxygen concentration was found to be 70.3% for the pocket mask and 97.5% for the BVM.</p><p>2）While indigenous bacteria were detected in the oral cavity of the subject, no bacteria were detected in the lungs of the mannequin. Conclusions：When 100% oxygen was supplied using a pocket mask, the oxygen concentration in the lungs was high and the filter was able to block the transfer of indigenous bacteria from the oral cavity into the lungs.</p>
