How to achieve blood
gas analyzer's quality control, calibration, maintenance?
Quality control of medical devices to monitor
blood gas analyzer should be every day for early detection and the exclusion of
measurement errors, ensure accurate and reliable measurement results.
Calibration is an analytical process, instrument calibration concentration and
other indicators of test, the correlation detection state to adjust to achieve
the best test accuracy and instrument state. Calibration requires two kinds of
calibrators and two bottles of premixed gas, the instrument automatically
performs quality control is the ultimate test calibration.
Anesthetic gas PO2
electrode, the value of anesthesia after the patient's PO2 will be disturbed,
while the normal blood pH of PO2 measurement is not affected. After infusion of
the patient, because the blood contains large amounts of liquid, easy to make
the measurement of the pH affected. Blood samples taken from such patients
should be tagged, this factor is taken into account so that the blood gas
analyzer results. Blood may not be squeezed, due to tissue fluid mixing will
seriously affect the measurement results. Blood retention time of less than 10
minutes at room temperature is appropriate. Measurements, when the testing room
air bubbles, should be re-measured time.
Maintenance should be
performed every day the first blood
gas analyzer cleaning procedures used to get rid of the sediments
of the testing department. Go protein procedures used to remove the detection of
the Ministry of protein deposits, a week or not 100 samples executed once, but
the recommendations do not specify other than high concentrations of
hypochlorous acid, as this will greatly shorten the life of the electrode
membrane, the membrane price expensive, not worth the candle. Troubleshooting is
divided into a general exception record measurement of the exception record
abnormal calibration records and internal error message.
