ADULT MOUTH-TO-MASK VENTILATION

In one-rescuer CPR, breaths should be supplied using a pocket mask, if available.
  1. Give 30 high-quality chest compressions.
  2. Seal the mask against the victim’s face by placing four fingers of one hand across the top of the mask and the thumb of the other hand along the bottom edge of the mask.
  3. Using the fingers of your hand on the bottom of the mask, open the airway using a head tilt/chin lift (do not do this if you suspect the victim may have a neck injury).
  4. Press firmly around the edges of the mask and ventilate by delivering a breath over 1 second as you watch the victim’s chest rise.
