When managing the airway during multiple-provider CPR, what is the correct technique for operating a BVM?

When managing the airway during multiple-provider CPR, the correct technique for operating a bag-valve-mask (BVM) involves sealing the mask with two hands using the E-C technique. This technique is crucial because it ensures a proper seal between the mask and the patient's face, which is essential for effective ventilation.

The E-C technique is named for the positioning of the hands: one hand forms the letter "E," with the thumb and index finger holding the mask in place, while the other hand forms a "C" to grasp the jaw and maintain the head tilt needed to keep the airway open. This two-handed approach provides a secure fit, enabling effective delivery of air and minimizing the risk of air leaking out from around the mask, which can compromise ventilation efforts.

Using a single hand or applying the mask loosely does not ensure an adequate seal, which can lead to ineffective breaths and insufficient oxygenation of the patient. Thus, mastering the E-C technique is critical for providers involved in a resuscitation effort to optimize patient outcomes.
