An oxygen mask with a bag, also known as a reservoir mask, is used to deliver a higher concentration of oxygen. Here’s how it works:
Understanding the Components
Before using the mask, it's helpful to understand its parts:
- Oxygen Tank: This is the source of the oxygen.
- Tubing: This connects the oxygen tank to the reservoir bag.
- Reservoir Bag: This bag stores the oxygen that will be inhaled.
- One-Way Valve: This valve connects the bag to the face mask and ensures that exhaled air does not enter the bag.
- Face Mask: This covers your nose and mouth and must form a tight seal.
Step-by-Step Guide to Using an Oxygen Mask with a Bag
Here are the steps for using the oxygen mask:
- Connect the Tubing: Attach one end of the oxygen tubing to the oxygen tank outlet and the other end to the connector on the reservoir bag.
- Fill the Reservoir Bag: Turn on the oxygen supply. Ensure the reservoir bag inflates to about two-thirds full before placing the mask on the face. This verifies oxygen flow.
- Position the Mask: Place the mask over your nose and mouth, ensuring a tight seal. This prevents oxygen from leaking out.
- Breathe Normally: Once the mask is correctly positioned, breathe normally. You are now breathing air from the reservoir bag, supplied by the oxygen tank.
- Monitor Oxygen Flow: Regularly monitor that the reservoir bag is inflating and deflating during breathing, which will ensure the system is working correctly.
Key Points to Remember
- The one-way valve ensures you are only breathing oxygen from the bag and not exhaled air. This enables the administration of high concentrations of oxygen.
- The mask must fit tightly to the face. An improper fit can cause leakage and reduce the efficacy of oxygen delivery.
- The reservoir bag should never fully collapse during inhalation and should also not be overflowing with excess oxygen. Either of these could indicate an issue.
Summary
| Component | Function |
|---|---|
| Oxygen Tank | Provides the source of oxygen. |
| Tubing | Carries the oxygen from the tank to the bag. |
| Reservoir Bag | Stores the oxygen before it's inhaled, ensuring a concentrated supply of oxygen. |
| One-Way Valve | Allows the oxygen to flow from the bag to the mask but prevents exhaled air from returning to the bag. |
| Face Mask | Covers the nose and mouth, providing a sealed area for oxygen delivery. |
In short, the oxygen flows from the tank, through the tubing, into the reservoir bag, and then through the one-way valve to the face mask for you to breathe.
