Which statement best describes the E-C technique for sealing a bag-mask ventilation (BVM)?

• A. It is a method to secure a good seal using the BVM.
• B. It is a technique for securing a tourniquet.
• C. It is a method for suctioning an airway.
• D. It involves mouth-to-mouth ventilation without a mask.

Answer: (A)

The E-C technique is all about getting a reliable seal on a bag-mask ventilator while keeping the airway open. One hand uses a firm C-shaped grip around the mask edge to press the mask against the face, forming an airtight seal. The same hand’s other fingers work to lift the jaw and open the airway (the E part, jaw thrust). When the seal is tight and the airway is open, you can squeeze the bag effectively with minimal air leaks. This is specifically for sealing the bag-mask device. It isn’t about placing a tourniquet, suctioning the airway, or performing mouth-to-mouth ventilation without a mask.
