- 1). Remove the CPR mask and the air valve (if separated) from its container. Expand it by pushing up on the plastic so that it pops out into an oval shape with the hole positioned on the top of the mask.
- 2). Attach the air valve to the hole on the mask.
- 3). Position the mask over the face of the injured person by putting the narrow part over the nose with the broader section over the chin.
- 4). Create an airtight seal on the mask by placing your hands over the sides and pressing it gently to the face of the injured.
- 5). Tilt the head of the injured person back to remove her tongue from the airway path and position your mouth over the valve and breathe into it.
