The manual resuscitator, or bag valve mask (BVM), represents the standard means for providing emergency ventilatory support. Despite its widespread use and the essential role it plays, it remains a skill with high variability regardless of a healthcare provider’s qualifications, training, experience, or confidence.
This may be attributable to inherent challenges in an emergency situation, coupled with the minimal safeguards available with BVM. Such variability can lead to hyperventilation, including overventilation, and/or hypoventilation, including underventilation, each carrying risks of severe complications such as aspiration pneumonia, lung injury, Acute Respiratory Distress Syndrome (ARDS) and even death.
