Which technique is used for maintaining a seal with the Bag Valve Mask (BVM)?

The "E-C" technique is designed specifically for achieving and maintaining a proper seal when using a Bag Valve Mask (BVM) to ventilate a patient. This technique involves using one hand in the shape of a letter "E" to hold the mask in position over the patient's face. The index and middle fingers are placed along the jawline while the thumb is positioned at the top of the mask to maintain a firm grip. The other hand forms the letter "C," which allows you to squeeze the bag effectively.

This method is particularly effective because it not only ensures a proper seal, preventing air from escaping, but also allows for the delivery of effective ventilations. Utilizing this technique maximizes the effectiveness of the BVM application, which is crucial in situations where the timely provision of oxygen is necessary.

Other techniques listed, such as the Two-Handed Technique, Head-Tilt/Chin-Lift, and Jaw-Thrust Technique, serve specific purposes for airway management but do not specifically address maintaining the seal of the BVM as effectively as the "E-C" technique does. The two-handed technique can provide additional stability but does not encompass the same sealing capability. Head-Tilt/Chin-Lift is primarily used for opening the airway rather
