1.Open mouth, clear airway of all foreign matter and fluids from the victim. The use of an Emergency Aspirator is recommended. Tilt head fully back wards and push the jaw upwards with neck stretched to open the airway.

2.To assist ventilation it may be beneficial to insert an artificial airway. Be careful that it does not push the tongue back and thus obstruct the throat.

3.Hold mask tightly to victim’s face,covering mouth and nose, tilt head fully backwards, mask-holding hand lifting jaw forward. Squeeze Ambu bag smartly and watch chest expand.

4.Release pressure on the manual resuscitator suddenly and allow the chest to deflate. Repeat 12-20 times per minute, or 30 times in the case of infants.If continued resistance to insufflation is encountered, check for airway obstruction or correct the backward head tilt. If adequate ventilation is not achieved with the manual resuscitation bag, immediately revert to expired air ventilation (mouth-to-mouth, or mouth-to-nose).

5. The correct ventilation frequency may vary. Please follow the current ventilation frequency recommended by national or international guidelines.

6. If the patient vomits during mask ventilation, immediately clear the patient’s airways of vomitus, then freely compress the bag valve mask a few times before resuming ventilation.

Pediatric and infant Version: The pressure limiting valve is open at 40 cmH2O.
