CO- 9.8.4 BAD LAB VALUES

For additional information about the Acid and Bicarb Pump CHECKS read parts a through f below
BEFORE performing them:
a) To ENSURE the Acid and Bicarb Pump volumes are delivering within +/- 2%, you MUST perform the
Test Concentrate and Bicarbonate Pumps per the Preventative Maintenance Procedures. This IS NOT
the CALIBRATIONS! It is a CHECK!
b) NEVER use a 50 ml burette. The additional pressure from the column may influence pump volume.
c) When pump strokes reach twenty (20) quickly turn [Dialysate Flow] off.
d) ACID PUMP VOLUME: If the twenty (20) stroke volume of the Acid Pump is not between AMIN and
AMAX calibrate the Acid Pump THEN return to Dialysis and repeat the check on the ACID Pump.
e) BICARB PUMP VOLUME: If the twenty (20) stroke volume of the Bicarb Pump is not between BMIN
and BMAX calibrate the Bicarb Pump THEN return to Dialysis and repeat the check on the BICARB
Pump.
f) If either pump needed to be calibrated this may have been the problem. If neither pump required
calibration ensure the Acid and Bicarb is good per clinic procedures.
