Which technique is recommended for holding the bag-valve-mask in place?

The recommended technique for holding the bag-valve-mask (BVM) in place is the E-C hand position. This method involves forming a "C" shape with the fingers on one side of the mask while using the thumb to create an "E" shape on the opposite side. This grip provides a secure fit on the patient's face, ensuring that the mask seals well over the nose and mouth, which is crucial for effective positive pressure ventilation.

Using the E-C grip allows the rescuer to have greater control over the mask positioning and ensures that air does not escape, optimizing the effectiveness of the ventilation delivered to the patient. This technique also allows the rescuer to use their other hand to squeeze the bag to deliver breaths.

In summary, the E-C hand position is recommended because it maximizes the seal and efficiency of ventilation provided by the bag-valve-mask device during resuscitation efforts.
