Single rescuer ventilation using a bag-valve mask with internal handle: a randomized crossover trial

Area of Science:

• Emergency Medicine
• Respiratory Care
• Medical Device Innovation

Background:

• Effective ventilation is critical in emergency care.
• Standard bag-valve masks (BVMs) are widely used but can present challenges in achieving optimal tidal volumes, especially during single rescuer use.
• Modifications to BVM design may improve ventilation efficacy.

Purpose of the Study:

• To compare the tidal volume delivered by a modified BVM with an integrated internal handle versus a standard BVM.
• To assess device preference among healthcare providers using a manikin model for single rescuer ventilation.

Main Methods:

• A randomized crossover trial involving 70 adult healthcare provider volunteers.
• Participants performed single rescuer ventilation on a manikin using both a modified BVM and a standard BVM at 10 breaths/minute for 3 minutes.
• Mean received tidal volume was the primary outcome, measured by the manikin; device preference was a secondary outcome.

Main Results:

• The modified BVM with an integrated internal handle resulted in a significantly higher mean tidal volume (90 mL greater) compared to the standard BVM (P < .0001).
• No significant difference in tidal volume was observed based on the order of device use.
• Eighty percent of participants expressed a preference for the modified BVM over the standard BVM.

Conclusions:

• The modified BVM with an integrated internal handle enhances mean tidal volume delivery during single rescuer ventilation in a manikin model.
• This modified BVM design shows potential as a valuable adjunct for improving ventilation effectiveness in emergency scenarios.
