Infant ventilation and oxygenation by basic life support providers: comparison of methods

Area of Science:

• Emergency Medicine
• Pediatric Resuscitation
• Cardiopulmonary Resuscitation

Background:

• Limited data exists on infant ventilation techniques used by basic life support (BLS) personnel.
• Effective ventilation is crucial for infant resuscitation outcomes.

Purpose of the Study:

• To compare the effectiveness of four ventilation methods (mouth-to-mouth, mouth-to-mask, pediatric bag-mask, adult bag-mask) by BLS providers on a 5kg infant mannequin.
• To assess the impact of airway patency on ventilation quality.

Main Methods:

• Fifty certified BLS providers performed five ventilation methods on an infant mannequin.
• Ventilation parameters including acceptable breath percentage, peak airway pressure, and delivered oxygen concentration were recorded.
• Statistical analysis (ANOVA) was used to compare methods and the effect of airway patency.

Main Results:

• No significant differences were found in acceptable breaths between pediatric bag-mask and adult bag-mask devices.
• Mouth-to-mask ventilation resulted in significantly fewer acceptable breaths compared to bag-mask devices.
• A patent airway significantly improved acceptable breaths and oxygen delivery across all methods.

Conclusions:

• Basic life support providers can achieve comparable infant ventilation using various methods, with bag-mask devices showing potential advantages.
• Ensuring airway patency is critical for optimizing ventilation effectiveness in infants.
• Further research may refine guidelines for infant resuscitation by BLS personnel.
