How long can a 42-liter oxygen bag last?

Oxygen bags are a relatively common type of medical equipment. They are often used by patients who need oxygen. How long the oxygen bag can last depends on how big the bag is, and it is also relatively easy to calculate. That's because the flow rate of a general oxygen bag is about two liters per minute. If it is a 42-liter oxygen bag, it can be used for about half an hour. Oxygen bags are used for first aid, so they are generally not used continuously.

How long can a 42-liter oxygen bag last?

In medicine, there is a medical device called an oxygen bag, which can also hold oxygen. People who are not familiar with it may find it strange, but it plays a great role in the contribution of medicine. So, how many hours can a 42-liter oxygen bag be used? What are the precautions?

Doctors remind us that the general flow rate of an oxygen bag is about 2 liters per minute, so a 42-liter oxygen bag can only be used continuously for about half an hour. Oxygen bags are generally used for first aid, so they are not used continuously. Therefore, the length of time using the oxygen bag must be adjusted accordingly based on the individual's actual situation. For the general population, the oxygen bag is used for half an hour in the morning and evening; students and white-collar workers can use oxygen bags when studying and working, and the time can be freely adjusted according to the study and work time; patients with chronic obstructive pulmonary disease need long-term low-flow oxygen inhalation, and the time is best to be more than 10 hours; the daily oxygen inhalation time for cardiovascular and cerebrovascular patients is 1-2 hours in the morning and evening every day. After using the oxygen bag, decide how long to use it based on how the symptoms are relieved.

There are several things to note when using oxygen bags:

1. Do not exceed the specified operating pressure of 10.6Kpa (about 0.1 kg/cm2) when oxygenating

2. When using for the first time, fill it with air, point the air outlet downward, and pat while exhausting to expel all the remaining isolation agent. 3. The amount of oxygen absorbed is adjusted with a clip. When the pressure is too low, pressure should be added outside the bag.

4. When the oxygen bag is filled with oxygen and is ready for use, please close the pressure head and avoid squeezing or approaching fire.

5. When the oxygen bag is not in use, it should be kept away from light, heat, contact with sharp objects and chemicals, and excessive squeezing. A small amount of air should be filled in the bag to prevent the tape from sticking during long-term storage.

6. Oxygen bags should be stored in a room without corrosive gases, with good ventilation and relative humidity less than 80%.

7. Maintenance: Keep clean. If there are water stains or dirt, wipe the oxygen bag clean with a wrung-out rag.
