Overview
- 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
Indications
- Respiratory failure
- Pre-oxygenation
- Emergent need to oxygenate/ventilate
Contraindications
No absolute contraindications
Difficult BVM (MOANS)
- Mask seal
- Obesity
- Aged
- No teeth
- Stiffness (resistance to ventilation)
Equipment Needed
- Bag connected to oxygen at 15L/min
- Mask connected to the bag
- Consider PEEP valve (provides PEEP between ventilations)
- OPA/NPA/adjuncts to facilitate successful BVM ventilation
- Suction
- SpO2 monitor helpful
Children
- Proper-sized mask (covers nose and chin)
- Proper bag (enough to see chest rise)
Procedure
"EC" Hand Position
- 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
2-person
- One person holds the mask with both hands (lateral edges)
- 2nd person bags
Rate
- Adult bag at 10-12/min
- Children 16-20/min
- Infants 30/min
- Neonates 40-60/min
Tidal Volume
- Avoid hyperinflation
- Bag until chest rise is seen
Complications
- 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
