Purpose: A conventional resuscitator is used as first-line equipment during cardiopulmonary resuscitation (CPR). However, resuscitation providers have difficulty in achieving adequate tidal volume during ventilation by conventional resuscitator (CR). This study was conducted to evaluate the usefulness of the newly-designed resuscitator (NR) during chest compression.
Method: Fifty nine individuals participated in this study. NR was produced by insertion of a silicon implant in the CR. The NR was set at a tidal volume of 500 mL. Subjects completed four procedures: CR without compression, NR without compression, CR with compression, and NR with compression. Individual characteristics were obtained and the results were analyzed statistically.
Results: The mean volumes for the CR without compression were 482.03 mL, NR without compression 513.71 mL, CR with compression 461.93 mL, and NR with compression 496.12 mL. When the two types of resuscitators were used during chest compression, success rate of CR of 64.4% was observed, and success rate of NR was 94.9% (p<0.01). The physical aspects including hand size, volume, and grip power showed no correlation with the volume that we delivered.
Conclusion: The NR can approximate the exact tidal volume and may be useful in preventing possible complications from inappropriately delivered tidal volumes.
