What technique is beneficial for making a secure mask seal while delivering breaths?

The E-C clamp technique is essential for achieving a secure mask seal when delivering breaths during a resuscitation effort. This technique involves using the thumb and index finger of one hand to form a "C" shape around the mask, while the other fingers are used to create an "E" shape that helps keep the airway open and the mask firmly in place. By applying this technique, the rescuer ensures that the mask effectively covers the patient’s nose and mouth, minimizing air leaks and maximizing the efficacy of ventilation.

In contrast to this technique, the jaw thrust maneuver is primarily used to open the airway, especially in suspected cases of spinal injury, and does not specifically address the securing of the mask for breath delivery. The head tilt-chin lift is another method used to open the airway, but similar to the jaw thrust, it does not provide a mechanism for effectively sealing the mask against the patient's face. The chin tuck method is also not aimed at securing a mask but rather focuses on maintaining a clear airway by positioning the chin correctly. Thus, the E-C clamp technique stands out as the most effective approach for securing a mask seal during ventilation.
