The amount of air a bag valve mask (BVM) can hold depends on its size, which is designed for different patient demographics. Based on the provided reference, the volumes for typical BVM sizes are:
- Neonate: 240 mL
- Paediatric: 500 mL
- Adult: 1600 mL
These volumes represent the typical capacity of the self-inflating bag itself, which dictates the maximum amount of air or oxygen that can be delivered with each squeeze. The specific volume delivered during ventilation (tidal volume) can be less than the full capacity, adjusted based on the patient's needs and response.
Bag Valve Mask Volumes by Size
Understanding the volume of a BVM is crucial for providing effective ventilation, ensuring the delivered breath is appropriate for the patient's size. The reference provides clear specifications:
| Patient Group | Bag Volume (Capacity) |
|---|---|
| Neonate | 240 mL |
| Paediatric | 500 mL |
| Adult | 1600 mL |
This table directly reflects the information provided by the reference regarding the typical volumes associated with different bag valve mask sizes used in ventilation. The choice of BVM size and the volume delivered are critical steps in patient care, impacting the success of manual ventilation.
