stored in the Endocrine cold room. Wash cartridges and waste containers are kept with other
blood gas consumables in the reagent store
-room, at
least one of each must be kept in the BGH
lab to be readily available if required by one of the wards.
Note
the analyser will display a visual warning when any cartridge is within 24 hrs. of expi
ry
or when there are less than 10% remains.
4
Clean analyser surface, small blood spots can be removed with 0.5% hypochlorite.
Report any misuse of analyser to ward manager and to senior BMS (e.g. blood spills used
syringes or needles left on analyser)
5
Chec
k and replace printer paper roll, instruction video available through user manual icon
(stock of paper with other blood gas analyser supplies in reagent store room)
6
Service or replace any failed sensors
Note that if any of the sensors have been replaced or disturbed then the analyser must be fully
calibrated and all levels of IQC measured before anyone is permitted access to analyse samples.
Used cartridges must be treated as contaminated waste and disposed at the site of use in
yellow clinical waste bags
Additional periodic maintenance
Check the maintenance logs for additional maintenance required. This should be undertaken on the daily
visit and performed
BEFORE THE DAILY PROCEDURES.
Complete the maintenance log
-
sheets for all activities
performed.
If glucose or lactate sensors are fitted, analyse the
Siemens
High G/L control weekly, (Core lab cold
room with glucose & lactate sensors), this should be on the last day before the weekend or Bank
Holiday break. Replace glucose or lactate sensors if this falls below the lower limit defined for the
control and as stated in the log
-
sheet.
Before performing maintenance procedures on any sensors, log onto the analyser using your access code.
Touch the
Status
icon followed by
Maintena
nce
and
Performing Sensor Maintenance.
To install glucose or lactate sensors
1)
Remove a sensor from fridge and
LEAVE IN THE SEALED PACKET AT ROOM TEMPERATURE FOR AT LEAST 30
MINUTES TO EQUILIBRATE (this prevents condensation on the electrode which would
render it unsuitable for use).
2)
Open the electrode compartment. Release the clamp on the right, which holds all sensors in
place.
3)
Remove the old sensor and install new, ensure that the sensor is making good contact at all four
points.
4)
Cl
ose compartment
5)
Calibrate the sensor.
N.B. the sensor may require up to 30 minutes before stabilizing and satisfactory calibration. If successful
calibration is not achieved after at least one hour and/or several calibration attempts, remove anothe
r
electrode from the fridge and install this after the 30 minute warm up period as described above.
