Abstract
Objectives: BVM ventilation performed by a female using the one-person technique, we aimed to elucidate whether the volume of air supplied is greater with the cheek-holding technique or the E-C technique, and how the volume of air supplied using the cheek-holding technique relates to the female’s physical characteristics.
Methods: A total of 57 female nursing students of a university performed BVM ventilation using the E-C technique and the cheek-holding technique. The airway portion of the mannequin was connected to a spirometer with which the volume of air supplied was measured. We also assessed height, body weight, body mass index, grip strength in both hands, and size of both hands.
Results: The mean volume of air supplied per breath was 548.0 ± 201.5 ml for the cheek-holding technique, and 403.2 ± 223.7 ml for the E-C technique. A significantly greater volume of air was supplied per breath with the cheek-holding technique than with the E-C technique (P < .001). There was no significant correlation found between the physical characteristic parameters of participants and the volume of air supplied per breath with the cheek-holding technique.
Conclusion: The cheek-holding technique resulted in a greater volume of air supplied per breath than with the E-C technique, and the air volume supplied was within the normal optimal range. Furthermore, there was no significant correlation with the female’s physical characteristics, which suggested that the cheek-holding method might serve to be an effective method of holding the BVM for one-person artificial ventilation by a female.
