In a situation where enough providers are available, what is the recommended technique for operating a bag-valve-mask (BVM)?

Utilizing the bag-valve-mask (BVM) device effectively is crucial for providing adequate ventilation to a patient in respiratory distress or arrest. The recommended technique involves sealing the mask with both hands in the E-C position. This technique is important because it helps create a tight seal against the patient's face, ensuring that air delivered from the bag goes directly into the lungs rather than escaping around the sides of the mask.

The E-C position involves using the thumb and index finger to form a 'C' shape around the mask, while the remaining fingers are positioned along the jawline to help maintain the airway and prevent obstruction. This method allows for better control during ventilation, ensuring that the mask remains snug against the patient's face while simultaneously providing a clear and open airway.

In scenarios where multiple providers are available, this technique enhances the breath effectiveness and minimizes the risk of inadequate ventilation due to air leaks. It also frees up one hand for securing the airway while the other hand remains free for squeezing the bag, thus allowing for synchronized and efficient ventilation.

Being familiar with this position and its application is essential for healthcare providers to ensure that they can perform BVM ventilation effectively in emergency situations.
