Oxygen inhalation by household oxygen generator has no obvious effect? The possible reasons may be (4-6)
4. Carbon dioxide retention
Patients with respiratory failure, especially those with type II respiratory failure, have severe small airway obstruction and difficulty in gas exchange, which prevents oxygen from reaching the body. Oxygen inhalation alone cannot solve the problem at this stage, because the body is prone to carbon dioxide retention due to insufficient ventilation. The ventilator can help expel carbon dioxide. At the same time, the oxygen concentrator needs to provide oxygen to supplement the body's oxygen saturation. The combination of the two can truly cure Effect.
5. No oxygen
In the case of no oxygen, it may be caused by improper interface connection. The specific troubleshooting method is as follows: adjust the air volume to the maximum, take a bowl filled with an appropriate amount of water, immerse the outlet of the nasal oxygen tube in the water, and observe whether there are bubbles and the size of the bubbles. If the air bubbles are relatively large, the air output is normal; if there are no air bubbles or the amount of air bubbles is small, the air output is abnormal. Check whether the connection between the oxygen outlet of the machine and the inlet of the humidification bottle and the outlet of the humidification bottle and the nasal oxygen tube is correct and whether there is any looseness. If there is a problem with the connection, reconnect it, and observe whether the cap of the humidification bottle and the body of the bottle are screwed tightly. If the oxygen output is still small, please contact product customer service.
6. Molecular sieve inactivation
Some users reported that after a regular oxygen concentrater has been used for a period of time, the gas flow at the oxygen outlet remains unchanged, but the oxygen concentration drops. My initial guess is that it may be caused by the inactivation of molecular sieves, but this is extremely rare. The reasons for the failure of molecular sieves may be 1) the use environment is very humid, such as in the kitchen and bathroom, it is easy for water vapor to enter the molecular sieve. 2) If there is a lot of dust in the home environment, it will also damage the molecular sieve. It should be used in a dry environment, and the filter cotton should be replaced regularly to ensure the service life of the oxygen concentrator.
