Using the Bag Valve Mask (BVM) for Non-Breathing Patients


When rescue breaths are not feasible, the Bag Valve Mask (BVM) becomes a vital tool for delivering ventilations to a non-breathing patient.

Components of the BVM

Let's examine the key components of the Bag Valve Mask:

  • Oxygen Supply: Connects to the BVM, enriching the system with oxygen.
  • Reservoir Bag: Oxygen reservoir ensuring optimal oxygen delivery to the patient.
  • Compressible Bag: Provides controlled oxygen flow during ventilation.
  • Valve Mechanism: Regulates the flow of oxygen during both inhalation and exhalation.

Using the BVM

Proper usage of the BVM is critical for effective ventilation:

  1. Positioning: Place the mask on the patient's face, ensuring a secure seal over the nose and chin, extending to the base of the chin.
  2. Airway Management: Open the airway fully using a head tilt chin lift technique to maximize airflow.
  3. Sealing: Gently push down on the mask to maintain a seal while avoiding excessive pressure.
  4. Two-Man Technique: For optimal control, it's recommended to use a two-person approach. One person secures the mask and airway while the other operates the bag for ventilation.
  5. Single-Hand Bag Compression: When squeezing the bag, always use one hand. Using two hands may cause lung trauma and complicate future ventilation efforts.

By following these guidelines, you can effectively utilize the Bag Valve Mask to provide essential ventilations to non-breathing patients.
