Common fault handling of spirometer tester
In recent years, with the rapid development of society and economy, spirometers have become more and more
In recent years, with the rapid development of society and economy, spirometers have become more and more widely used in our daily life. However, we usually encounter some problems in the process of using the spirometer. Let's take a look at how to deal with the failure of the spirometer.
1. Unable to establish communication. Common mistakes and troubleshooting methods are:
1) The power of the host is not turned on. Remedy: Turn on the power switch and make sure that the green indicator of the host power is always on.
2) The connecting cable between the host and the computer is disconnected. Remedy: Check the cables and make sure they are properly connected and making good contact.
3) Computer virus damage. Remedy: Restart the computer, enter the "One-Key Recovery" program, and restore the computer to the state that was installed and debugged.
2. After entering the ventilation function check program, the patient's breathing curve cannot be stable, and it always drifts up or down. Cause of failure: The sensor zero point is wrong. Remedy: Exit the program and re-run the program. There is also a possibility that after the flow sensor is cleaned, there is water on the flow pressure measuring port, which blocks the pressure measuring tube and causes the breathing curve to drift. Remedy: After removing the water droplets, exit the program and re-run the program.
3. The amount of dispersion is very high. Cause of failure: There is air leakage (the suction valve is not closed tightly, the interface is loose, etc.), and some air is inhaled.
4. The amount of dispersion is low. Cause of failure: The main valve of the gas cylinder is not opened or the pressure is too low after the adjustment of the decompression gauge.
The above is an introduction to the common fault handling of the spirometer. I hope you can pay more attention to the above content.
