    Hospital staff are hesitant to perform mouth-to-mouth resuscitation when bodily fluids or infection are present. A resuscitation mask offers a safer, more effective alternative for emergency ventilation during cardiopulmonary resuscitation (CPR).

    Area of Science:

    • Emergency Medicine
    • Cardiopulmonary Resuscitation
    • Medical Device Technology

    Background:

    • Hospital staff face challenges performing ventilation during cardiopulmonary resuscitation (CPR) due to concerns about patient contamination.
    • Willingness to use ventilation methods like mouth-to-mouth or mouth-to-mask is significantly impacted by the presence of vomitus, secretions, and infection.

    Purpose of the Study:

    • To assess hospital staff's willingness to use ventilation methods during CPR in the presence of contaminants.
    • To evaluate the effectiveness of different ventilation techniques, including mouth-to-mouth, mouth-to-mask, and bag-valve-mask, before and after instruction.
    • To identify the most effective and accepted method for emergency ventilation.

    Main Methods:

    • A questionnaire was administered to 70 hospital staff members regarding their willingness to use ventilation methods during CPR.

  • 35 participants were tested on their ability to achieve adequate tidal volume (800 mL) using a manikin with various ventilation devices.
  • Ventilation effectiveness was assessed before and after instructional training.

    • Main Results:

    • Only 13% of staff would use mouth-to-mouth ventilation, while 59% would use mouth-to-mask ventilation when faced with vomitus, secretions, or infection.
    • Mouth-to-mouth ventilation showed the best initial performance.
    • After instruction, mouth-to-mouth and mouth-to-mask ventilation performance improved, but bag-valve-mask ventilation had a 97% failure rate, indicating potential inappropriateness for CPR.

    Conclusions:

    • A specialized resuscitation mask is recommended for emergency ventilation, offering effective, contamination-free, and oxygen-supplemented resuscitation.
    • This mask is identified as the most cost-effective and well-accepted method for emergency ventilation, addressing staff concerns and improving patient outcomes.
