Why is the filter placed between the oxygen meter and the oxygen cylinder? This is because the oxygen in the cylinder may be affected by external contaminants during storage and transportation, such as dust, impurities, grease, etc. These contaminants will affect the purity and cleanliness of the oxygen. The oxygen meter, on the other hand, is used to regulate the flow rate of oxygen. If there are impurities in the oxygen, the accuracy and stability of the meter will be affected, thus affecting the effectiveness and safety of oxygen therapy. Therefore, installing a filter between the oxygen meter and the oxygen cylinder can effectively filter out the impurities in the oxygen and ensure the purity and cleanliness of the oxygen.
Practical answers:
1. Replace the filter regularly. Filter is a wearable component, after using for a period of time it will lose its filtering effect, so it needs to be replaced regularly. Generally speaking, the service life of the filter is about 3 months, the specific time also depends on the actual situation.
2. Pay attention to the installation direction of the filter. The filter generally has an inlet and an outlet, when installing, pay attention to the direction of the inlet and outlet, otherwise the filter will not work properly.
3. Pay attention to the cleaning and maintenance of the filter. Before replacing the filter, the filter needs to be cleaned and maintained to extend the service life of the filter. The cleaning process should be scrubbed with water or alcohol and dried for use after cleaning.
In conclusion, the role of oxygen meter filters is very important to ensure the effectiveness and safety of oxygen therapy. Therefore, when using oxygen therapy, pay attention to the use and maintenance of the filter to ensure the purity and cleanliness of oxygen.
