You attach oxygen to a bag valve mask (BVM) by connecting the oxygen tubing to the BVM's oxygen inlet and then connecting the other end of the tubing to an oxygen source, such as an oxygen cylinder regulator or an in-ambulance oxygen regulator.
Here's a breakdown of the process:
-
Identify the Oxygen Inlet: Locate the oxygen inlet on the bag valve mask. This is usually a small nipple or connector located on the bag itself or near the mask connection.
-
Connect the Oxygen Tubing: Securely attach one end of the oxygen tubing to the BVM's oxygen inlet. Ensure it's a tight fit to prevent leaks.
-
Connect to the Oxygen Source: Attach the other end of the oxygen tubing to the regulator connected to an oxygen cylinder or the regulator within the ambulance's oxygen supply.
-
Adjust Oxygen Flow Rate: Set the oxygen flow rate on the regulator as prescribed (typically 10-15 liters per minute). This will provide a sufficient concentration of oxygen to the patient.
Important Considerations:
- Check Connections: Always double-check all connections to ensure they are secure and leak-free.
- Oxygen Concentration: Using supplemental oxygen with a BVM significantly increases the inspired oxygen concentration delivered to the patient compared to using room air alone.
- Reservoir Bag: Many BVMs have an oxygen reservoir bag that attaches to the BVM. Make sure the reservoir bag is properly connected as it helps to deliver higher concentrations of oxygen.
By following these steps, you can effectively attach oxygen to a bag valve mask and provide supplemental oxygen to a patient in need of respiratory support.
