- Confirm unresponsiveness, open the airway using a head-tilt/chin-lift, and position the mask with the apex on the bridge of the patient's nose.
- Achieve an airtight seal using the C-E clamp technique: form a 'C' over the mask with your thumb/index finger and an 'E' along the jawbone with your other fingers.
- Deliver slow, steady breaths into the one-way valve, watching for visible chest rise and fall.
- Continuously monitor the patient's airway for obstructions like vomit through the transparent dome.
- For trained personnel only: Attach supplemental oxygen tubing to the O2 inlet port to increase oxygen delivery during resuscitation.
