Study Notes

Bag-Mask Device Overview

A bag-mask device provides positive-pressure ventilation for victims who are not breathing or breathing abnormally.
It consists of an inflatable bag attached to a face mask.
If self-inflating, it can be used with or without supplemental oxygen.
Without oxygen, it delivers approximately 21% oxygen from ambient air.
Some devices include a one-way valve, which may differ among various models.

Steps for Proper Usage of a Bag-Mask Device

Position directly above the victim's head to ensure optimal visibility and access.

Proper Mask Placement

Place the mask on the victim's face, aligning it using the bridge of the nose as a guide.

E-C Clamp Technique

Hold the mask firmly in place while opening the airway by using the E-C clamp technique:
- Perform a head tilt to ensure airway is clear.
- Position the mask with the narrow end at the bridge of the nose.
- Form a "C" shape with your thumb and index finger to grip the sides of the mask, pressing it to the face.
- Use fingers of the opposite hand to lift the jaw, creating an 'E' shape to maintain an open airway and reinforce mask contact.

Delivering Breaths

Squeeze the bag to provide breaths, ensuring each breath lasts about 1 second.
Observe for chest rise with each breath to confirm effective ventilation, regardless of whether supplementary oxygen is used.
