An aerosol mask is one of the oxygen delivery devices. It is a simple respiratory face mask which consists of holes on two sides for breathing out the air. The mask covers both mouth and nose. An elastic connects to both ends of the mask which goes back of the head.
It is widely used in hospitals and houses to treat normal patients.
- The value of FiO2 ranges from 40% to 60%.
- Flow rate normally ranges from 6 to 10 liters per minute. If you set it below 6 liters/min there is a chance that the atmospheric gas will enter into the nostril through the holes on both sides of the mask.
- It is a low flow device.
- Humidification may or may not be needed.
- It has got a reservoir capacity of about 100 ml to 250 ml.
- An aerosol mask should be used only for a short period of time and should later be replaced with a nasal cannula. Exposure to high oxygen concentration is toxic to the human body.
- Suitable for both nose and mouth breathers
- Patients will not be able to eat or talk by using this mask
- Difficult to fix this aerosol mask in the face for a longer period of time. Due to this reason, there is a high chance of leakage of the air from the mask.
- If the patient uses the mask for a long period of time, the elastic can cause pain and red marks around the ear loop.
- There is also a high chance of rebreathing of the exhaled air.
It is one of the cheapest oxygen delivery devices available in the market. The market value of the aerosol mask ranges from Rs 80 to Rs 100.
These respiratory masks can last for over a year. But, I recommend you, replace it between 6 months to 9 months of use.
- You can use soap water to clean the mask and the connecting tube.
- Vinegar can also be used for cleaning but it will give an unpleasant smell once the mask has been dried out.
- Do not use bleaching powder or alcohol for cleaning. They are highly corrosive in nature.
