ES ph noise 1214031005

Dear Hanna,

I have this ES that keeps acting up - 

"On 21.10.19 we exchanged the electrodes for pH and the reference electrode. On 22. and 23.10. we had no patients to measure. On 24.10. I then drove the interlaboratory test BGA and received the error message pH RAUSCHEN for the first time. Then I had to get new samples for the ring test. I had also informed you that even with your loaner the error pH RAUSCHEN =noise occurs. Since we used the same electrodes for the loaner and for our device, it can be concluded that the cause of the fault is less in the device than in the electrodes.

 

I strongly suspect that one of the two electrodes (pH or reference electrode) is out of order.

 

Currently the error message pH is RAUSCHEN = noise during the 1st measurement of a patient; if we then calibrate and take blood again, we get results. It is questionable for me how long we can help ourselves so; besides, this procedure is unacceptable."

should we as our customer wants exchange the electrodes?

i one of your first emails in regards to this you indicated it might be sample handling by the user?

see attached measurements.

best regards from MEDICA trade fair Düsseldorf

  • RE: ES ph noise 1214031005

    Dear Tobias,

     

    Thank you very much for your email and print outs.

     

    1. Could you please answer my questions in my previous email. ( Please see the attached email- We really want to know about the kind of sample that you are testing- Are you using our capillary kit ? Did you run the Normal QC as a patient sample in the capillary mode? )

    2. I looked at all the calibration and the QC results. They are good and within the normal ranges. Some of the patient results are good too, only sometimes you are getting the noise( ****) error on the patient results. ( For example some results on  11/18 and 11/14 ) This indicates the sample handling issue( Delayed sample analysis-Bubbles in the sample- Please see the ES sample handling )

    3. As I mentioned in the capillary mode the chance of the pH getting exposed to the air is very high. Changing the pH causes some changes in PO2 and PCO2 as well.

    4. Regarding your first sentence: Did you get the noise error for the patient samples? Or for the calibration?

    4-1- After you got the new samples, did you get the same error( pH noise ) on the patient sample?

    1. Please send us the calibration print out, QC print out and the patient results print out after the new pH and reference electrode.

    2. I would recommend to install a new pH and reference electrode on the ES loaner, do the calibration, run the QC on both analyzers then run the same patient samples on loan analyzer and ES with the serial number 1214031005 at the same time. Please send us the results and indicate the analyzers serial numbers on the print outs.

     

    Enjoy the Medica Trade show. We have a new member for our Sales and Marketing team her name is Inge, she is from Germany too.

     

     

    Looking forward to hearing back from you!

    Dear Tobias,

     

    Thank you for the information and print outs.

     

    The ES analyzer will not show the calculated results if the calibration results are not good or if the calculated results are out of the range. ( Please see the attached from user manual )

     

    1. Looking at the calibration print outs they are all good and within the normal ranges.

    2. Could you please let us know what is the serial number on this analyzer?

    3. Are you using Medica capillary tubing kit for ES? Please send us the part number or a picture of the kit.

    4. Which kind of sample are you testing?

    5. The print outs show that you are using the capillary mode. In the capillary mode the chance of the pH getting exposed to air is very high. When pH changes the PCO2 and PO2 also change.

    6. Please run the normal QC as a patient sample and see if you get the same error. Please send us the calibration print out and this print out.

    Subject: ES noise & drift

     

    Dear Hanna,

    a clinic has just installed a new reagentmodule 19071029 - they have now faced a variety of problems with pH noise and pO2 drift.
    See attached printouts. Should we troubleshoot the module, or the device?
    best regards
    Tobias
