The blood gas analyzer used to analyze the pH of body fluids, carbon dioxide partial pressure and oxygen

partial pressure within the pipe system is more complex, the failure rate is a lso higher. But belong to the

electronic circuit failures are rare, most of the error for the flushing or calibration failure and gas.

Denmark, the ABL-3 series, the following example, describes the troubleshooting methods.

    A flush or set the standard fault handling:

    Flushing or calibration such as FUNTIONERROR, FLUSHERROR ,2-POINTCALNEED such as error messages, the

following maintenance steps can be taken:

    (1) to check the washing fluid bottles, red, green and calibration solution bottle with or without

liquid. And then observe the distilled water wet towers and two calibrators balance tower, the surface

normal, moderate and has bubbles. Bubbles, such as a tower, this tower associated piping must be blocked.

Distilled water wet tower is the most easy to fouling, pumping distilled water to remove the tower shell

clean. Cleaning set the standard liquid associated pipelines, you can turn off the CO Cylinders, remove the

red and green calibrator bottle. In V2, V3, Department set aside calibrators tower over the pipeline (red and

green hat tag) using a syringe to inject the appropriate calibrators, showing that given the increase in

tower liquid level of the standard solution, distilled water wetlands of the tower of the hollow column

liquid pouring slot to install the calibrator bottle plume emission. This indicates that calibrators tower

linked to the pipeline has been smooth.

    â'¡ rarely the case of V5, V9, V1l valve in the pipeline is damaged, it can be seen the leaking of these

parts, there are crystals.

    â'§ observe the VSA, VSB liquid sensor. RINSE button is pressed, the blood gas analyzer, washing, f lushing

fluid through the main pump pipe to reach the VSB liquid sensor, the indicator light on the VSB is can be

seen along the pipeline direction. The indicator light turns off when not flushing fluid in the pipeline.

Similarly, when the press CAL calibration, the calibration solution has to reach VSA and VSB, the above

indicator light. If you press the flush button or calibration key, see the pipeline flushing solution or

calibration solution to reach the VSB is, the VSA sensors, but its ± surface indicator does not light. Or

when the VSA, VSB is the sensor in the pipeline liquid through the top of the indicator has been bright, the

fault is in the VSA, VSB is the valve. Under test VSA or VSB plug aside (sometimes due to the plug oxide or

dirt lead to poor contact) spray cleaners, alcohol, or electronic equipment after cleaning plug it back in,

boot to try. I f the lights are still on the VSA, VSB is not normal, then you need to replace the VSA or VSB

re-test.

    Two gases error:

    Error message GASERROR. First check the adequacy of the CO2 pressure gauge on the CO2 cylinder. Remove

the air filter boot on the screen the \"GASERROR\" disappear, then the fault from the air filter in front of.

Airbags ball blowing air filter to see if the obstruction. Along the tubes of the air filter, you can see the

pipe the other end there is a connection hole, in many cases there are clogged with dust, take a wire through

a pass, you will find the dust sediments to fall out. This is due to air at the entrance to the long-term

inhalation of air into the instrument, and dirt over time, the airways to narrow, resulting in a serious

shortage of gas flow, causing the machine to gas an error message. This usually pay attention to reduce the

blood gas analyzer ambient dust.
