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.
