To use an oxygen mask effectively, especially types with a reservoir bag, specific preparation and application steps are necessary to ensure proper oxygen delivery.
Using an oxygen mask involves preparing the mask, placing it correctly on the face, and securing it to ensure a tight seal for optimal oxygen delivery.
Here are the general steps for using an oxygen mask, focusing on a common type like a non-rebreather mask that includes a reservoir bag:
1. Prepare the Mask
Before applying the mask, it's crucial to prepare it to ensure it functions correctly.
- Connect to Oxygen Source: Connect the tubing from the mask to the oxygen source (e.g., an oxygen tank or wall connection) and set the prescribed flow rate, usually at a high flow rate for masks with reservoir bags (e.g., 10-15 liters per minute).
- Pre-fill the Reservoir Bag: For masks with a reservoir bag, cover the valve(s) and allow the bag to fill with oxygen. The reference video segment highlights the importance of ensuring the reservoir bag works as expected by "deflating it. And then refilling it again". This process confirms the bag fills properly and is ready to provide a continuous supply of high-concentration oxygen during breathing. Ensure the bag remains partially inflated during use.
2. Place the Mask on the Face
Carefully position the mask over the individual's nose and mouth.
- Ensure the mask covers both the nose and mouth completely.
- The chin piece should fit snugly under the chin.
3. Secure the Mask
Use the elastic strap to hold the mask in place.
- Bring the elastic strap around the back of the head, typically resting above the ears.
- Adjust the tension of the strap so the mask fits snugly against the face, creating a good seal without being uncomfortably tight. A secure fit minimizes oxygen leakage.
- Mold the metal strip over the bridge of the nose to conform to the individual's facial shape and prevent air leaks around the nose area.
4. Monitor and Adjust
Once the mask is in place, observe the individual's breathing and check the mask's function.
- Ensure the reservoir bag remains partially inflated with each breath. If it collapses completely, the oxygen flow rate may need to be increased or the mask seal checked.
- Check that the individual is comfortable and receiving adequate oxygen, looking for signs like improved skin color or easier breathing.
- Periodically check the oxygen supply level.
Following these steps helps ensure that the oxygen mask delivers the intended concentration of oxygen efficiently and safely. Always follow specific instructions provided by healthcare professionals or included with the oxygen equipment.
