Abstract
|
|
|
Purpose: A manual resuscitator is often used during cardiopulmonary resuscitation. Artificial ventilation during cardiopulmonary resuscitation is important to the victim’s survival. But, manual resuscitators can not achieve delivery of optimal tidal volumes during cardiopulmonary resuscitation. Hence, we suggest a newly designed manual resuscitator that achieves optimal tidal volumes.
Methods: This study was done on sixty one participants using a conventional manual resuscitator and a newly designed resuscitator. Each participant squeezed the resuscitators ten times. We measured tidal volumes and participant variables including age, sex, type of emergency medical practitioner, hand height, hand grip strength, and hand volume.
Results: For the 61 patients, mean tidal volume with the conventional resuscitator was 501.67±143.95 ml and with the newly designed resuscitator it was 527.14±23.77 ml (p=0.156). Accuracy of the conventional resuscitator was 19.7%; for the newly designed resuscitator it was 91.8%. Tidal volume did not correlate with age, sex, type of emergency medical practitioner, hand height, hand grip strength, or hand volume.
Conclusion: Our newly designed resuscitator was better able to ventilate optimal tidal volumes than a conventional resuscitator. Further study with the newly designed resuscitator should be done in the clinical setting.
