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

• A. The three smallest fingers of one hand under the chin
• B. Thumb and index finger across the mask
• C. The ring and pinky fingers under the chin
• D. All five fingers around the mask

Answer: (A)

In the E-C technique for bag-valve-mask ventilation, the seal is built with two hands working together: one hand forms the seal around the mask (the “C” grip) while the other lifts the jaw to create an open airway (the “E” grip). The part that forms the “E” is created by placing the three smallest fingers—the pinky, ring, and middle fingers—under the patient’s chin to lift the mandible and bring the jaw forward. This jaw lift opens the airway and creates a stable channel for ventilation while the other hand maintains the mask seal. The remaining fingers handle the mask seal with the thumb and index finger. The other choices don’t fit because they either describe the seal around the mask itself, omit the jaw-lift action, or involve using the wrong combination of fingers.
