What is the correct order of steps for using a bag-mask device?

• A. Position yourself directly above the person's head. 2) Place the mask on the person's face, using the bridge of the nose as a guide for correct positioning. Use the E-C clamp technique to hold the mask in place while you lift the jaw to hold the airway open. 3) Squeeze the bag to give ventilations while watching for chest rise. Deliver each ventilation over 1 second, with or without the use of supplemental oxygen.
• B. Place the mask on the person's face first. 2) Position yourself above the head. 3) Squeeze the bag to ventilate.
• C. Squeeze the bag first. 2) Place the mask on the face. 3) Position above the head.
• D. Position above head. 2) Lift jaw. 3) Squeeze bag.

Answer: (A)

The key idea is to secure an open airway and a good mask seal before delivering breaths. Start by getting yourself directly above the person’s head so you can control the seal and watch the chest as you ventilate. Place the mask on the face using the bridge of the nose as a guide to sit correctly over the mouth and nose. Then use the E-C (C-E) clamp technique to hold the mask in place while you lift the jaw forward to keep the airway open; this combination gives you a stable seal and an open airway at the same time. Once the seal is secure and the airway is open, squeeze the bag to ventilate, delivering each breath over about 1 second and watching for chest rise to confirm effective ventilation. You can provide oxygen if available, but ventilation should proceed with or without supplemental oxygen.
