How to Adjust The Flow Rate of The Oxygen Generator?

Before answering this question, you must first ensure that the oxygen concentration of your machine reaches more than 82% of the international minimum medical oxygen concentration standard.

1. According to the blood oxygen concentration in the body

To judge whether a person is hypoxic, the core indicator is to look at the blood oxygen concentration in the body. You can buy an oximeter and clip it on your finger.

Normal blood oxygen concentration is 95-100%

Example 1, when the flow rate is adjusted to 3L or 5L, and the blood oxygen concentration is different

If the patient is not on oxygen, the blood oxygen concentration in the body is 80%

When the oxygen generator flow is adjusted to 3L for oxygen inhalation, the blood oxygen concentration is 92%

When the flow rate of the oxygen generator is adjusted to 5L for oxygen inhalation, the blood oxygen concentration is above 95%

The flow rate of the oxygen generator is preferentially adjusted to 5L

Example 2, when the flow rate is adjusted to 3L or 5L, and the blood oxygen concentration is the same

If the patient does not receive oxygen, the blood oxygen concentration is 80%

When the oxygen generator flow is adjusted to 3L for oxygen inhalation, the blood oxygen concentration is 95%

When the flow rate of the oxygen generator is adjusted to 5L for oxygen inhalation, the blood oxygen concentration is above 95%

The flow rate of the oxygen generator is preferably adjusted to 3L.

After the patient inhales oxygen, when the blood oxygen concentration in the body is the same, the flow rate is preferentially adjusted to the minimum, which can prolong the life of the oxygen generator.

2. According to the disease, listen to the doctor's advice and use the scene

1. Doctor's suggestion: The doctor will tell you how many liters the oxygen generator flow should be adjusted to.

2. According to the condition: COPD, pulmonary heart disease, emphysema and other pulmonary diseases, when using the oxygen generator alone, the flow rate should be adjusted to below 3L/min.

3. According to the usage scenario: When a lung patient needs to be connected to a ventilator, use the oximeter data index as a reference value and use 5-10L/min. Again, the oxygen concentration is above 82% of the international medical standard.

When the oxygen generator flow is adjusted to 3L for oxygen inhalation, the blood oxygen concentration is 95%

When the flow rate of the oxygen generator is adjusted to 5L for oxygen inhalation, the blood oxygen concentration is above 95%

The flow rate of the oxygen generator is preferably adjusted to 3L.

Third, according to their own comfort

Some people are reluctant to spend money on an oximeter, what should they do? That can only be judged by one's own comfort level, which is more subjective. Many of the sick people are elderly people, and their body's nerve sensitivity is not so high. I don't know if there is any effect after inhaling oxygen. I have seen an asthma patient who bought a 1L oxygen generator and inhaled ineffective oxygen for a year.

Some people think that more traffic is better. Especially in the hospital, people are used to inhaling oxygen. The hospital uses industrial oxygen production, and the flow rate is relatively large. After the patient returns home, he feels that the flow rate of the home oxygen generator should be the same as that of the hospital. Therefore, patients often say that the home oxygen concentrator has no wind and the flow is too small. Before many patients buy the machine, I will also tell the patient the difference between the home oxygen concentrator and the hospital flow.

4. According to the length of the oxygen inhalation tube

The commonly used oxygen inhalation tubes are 2 meters, 3 meters, and 4 meters. Some patients use 5-10 meters of oxygen inhalation tubes at home for the convenience of movement.

The flow of the oxygen generator will be attenuated. When your oxygen inhalation pipe is longer, the flow will be attenuated more severely, and the flow of the oxygen generator will be greater. This article suggests that if conditions permit, the shorter the better, the longer the oxygen inhalation tube can be used for sleeping at night.

The above four methods are for reference only, and the method that suits you is the best method.
