The E-C technique is a way to secure a good seal using the BVM. E-C indicates how you place your fingers and thumbs to form the seal. Which statement best describes this technique?

• A. The E is formed by the three smallest fingers of one hand, under the chin of the casualty, and the C is formed by the thumb and the pointing finger as they encircle the cup of the BVM and press it over the mouth to make a seal.
• B. The E is formed by the thumb and index finger, and the C is formed by the middle and ring fingers encircling the cup.
• C. The E is formed by the four fingers of both hands, and the C is formed by the little finger around the cup.
• D. The E-C technique uses a standard bag to seal without finger placement.

Answer: (A)

To get a solid seal on the bag-valve-mask, use the E-C technique to separate jaw lift from the seal. The E is created with the three smallest fingers of one hand placed under the casualty’s chin to lift the jaw and open the airway. This jaw elevation helps move the tongue forward and creates a clear path for air flow. The C is formed by the thumb and index finger around the mask’s cup, pressing the mask onto the face to establish a tight seal. This combination lets one hand lift the jaw while the other hand maintains a secure seal, reducing air leaks and improving ventilation effectiveness. The statement that matches this arrangement—three small fingers under the chin for the E and the thumb and index finger encircling the mask to seal—best describes the technique.
