In the E-C technique, which fingers form the 'C' portion of the seal?

• A. Thumb and pointing finger encircling the cup of the BVM
• B. Index and middle fingers around the cup
• C. Ring and little fingers around the cup
• D. Pinky finger around the cup

Answer: (A)

In the E-C technique for sealing a bag-valve-mask, the seal portion labeled as the “C” is made by the thumb and index finger forming a pinch around the edge of the mask (the cup). This grip creates a tight, uniform seal against the face. The other three fingers then cradle under the chin to lift the jaw and help maintain the airway, completing the “E” part of the grip. That’s why the best choice is the thumb and index finger encircling the cup of the BVM—this specific finger combination is what creates the effective seal around the mask. Using other finger pairs wouldn’t produce that same secure edge seal, and the seal would be less reliable.
