Bag valve mask ventilation: Difference between revisions

Revision as of 21:18, 21 November 2020

Simple, life-saving skill that is critical in airway management
Deliver oxygen at positive pressure via a bag containing oxygen connected to a mask placed over a patient's nose and mouth
Oxygenation and ventilation prior to definitive airway placement or bridge to sedative metabolization

No absolute contraindications

Thumb and index finger holding mask in a "C" position
- Thumb superior and index inferior
3rd, 4th, 5th finger hold the mandible and perform a jaw thrust
Other hand used to bag

One person holds the mask with both hands (lateral edges)
- With double CE technique, index fingers and thumbs of both hands form C over mask and digits 3-5 lift the jaw at the rami of mandible
- Can also press thumbs and thenar eminences over lateral edges of mask and use digits 2-5 to lift jaw at the rami of the mandible
- Important to life jaw into mask and not press mask down into jaw; can occlude the airway and cause difficulty with ventilation
2nd person bags

Poor seal
- Remove dentures to intubate; keep them in to bag/mask ventilate
- For a beard can smear lube to help create better seal
Poor oxygenation/ventilation
- Readjust head-tilt-chin-lift or jaw thrust
- Utilize oropharyngeal airway/nasopharyngeal airway
Overinflation of the stomach causing emesis/aspiration
