When using a bag-mask device on an unconscious adult, what is the correct order of steps?

• A. Squeeze the bag to give breaths, then place the mask on the face, then clamp the mask with E-C technique.
• B. Place the mask on the victim's face using the bridge of the nose as a guide, use the E-C clamp technique to hold the mask in place while you lift the jaw to open the airway, and squeeze the bag to give breaths (1 second each) while watching for chest rise.
• C. Apply the AED pads before giving breaths and then deliver breaths while the chest rises.
• D. Check responsiveness, then call for help, then start compressions before masking.

Answer: (B)

When ventilating with a bag-mask device, the priority is a reliable seal and an open airway before delivering breaths. Start by placing the mask on the face so the edge sits securely and the bridge of the nose helps guide proper placement. Next, use the E-C clamp technique to hold the mask in place with two hands while you lift the jaw to open the airway. With the airway open and the seal solid, squeeze the bag to give a breath for about one second, watching for chest rise. Repeat at a rate of roughly 10–12 breaths per minute. This sequence ensures effective ventilation by securing the airway and seal first, then delivering breaths.
