Abstract

The aim of this study was to examine the effectiveness of headband (HB) usage for nurses to mask ventilation. This study was a randomized crossover trial focusing on ventilation volume and mask fit pressure distribution. Forty nurses participated in this study. Subjects performed a mask fit using the C method (E-C usage method only) and H method (E-C usage method with HB) on the airway simulator. In addition to the ventilation volume, we measured the mask′s pressure distribution using a pressure measurement sheet. Ventilation volume was significantly higher with the H method than the C method. Pressure was significantly higher on the nose, right cheek and both corners of the mouth with the H method. Furthermore, the pressurized area was significantly higher at all sites except the jaw using the H method. The difference in maximum ventilation volumes between the C and H methods was most affected by the difference in the pressurized area at the right corner of the mouth. These results suggested that nurses′ HB use for mask ventilation could increase ventilation volume by covering a mask fit ventilation on the right corner of the mouth compared with the E-C method.
