6 Principle Introduction
The system utilizes potentiometry and amperometry to determine the concentrations of blood
gases and blood chemistries, and utilizes conductivity to determine the concentration of Hct.
Many parameters can also be calculated such as cH+, HCO3-act, HCO3-std, BE(ecf), BE(B),
BB(B), and so on.
6.1 Measurement Method
Methods
Measurements are performed on undiluted specimens. Undiluted methods are also called direct
methods, whereas methods that dilute the sample are called indirect methods.
For electrolytes, direct methods measure the free ion concentration of analyte (apparent or free
ion activity) per unit volume of plasma water, and indirect methods measure the concentration of
analyte per unit volume of plasma. It is known that the direct method gives the clinically
significant result for electrolytes. When there is disagreement between the methods, such as when
the patient has abnormal total protein or lipid levels, it results from interference on the indirect
method. At normal levels of protein and lipids the systematic offset between methods is often
corrected for in commercial direct measuring instruments so that the normal ranges for all
instruments are in agreement. Sensors have been calibrated in the manufacture so that normal
ranges are in agreement with indirect reference methods at normal levels of total protein and
lipids.
Direct measurement of hematocrit by the conductometric technique gives a result related to the
non-conducting excluded volume fraction of the sample. Red blood cell volume is the
predominant component of the nonconducting volume, but proteins, lipids, and white blood cells
also contribute. Elevated hematocrit readings are expected at abnormally elevated levels of these
components. Decreased hematocrit readings are expected at abnormally low levels of protein,
such as found in hemodiluted samples taken from cardiopulmonary bypass. Osmotic imbalance
causes a discrepancy between direct (conductometric, spun) and indirect (Coulter) measurements
because of variation in the meancell volume.
Sensors
Sensor refers to the electrode embedded in test cartridges. There are three different types of
sensors:

i15 Blood Gas and Chemistry Analysis System Service Manual
Potentiometric Sensor
Amperometric Sensor
Conductometric Sensor
Troubleshooting
Potentiometry: A potential is recorded using a voltmeter, which relates to the concentration of
the sample. A reference electrode is used to provide a stable, fixed potential against which other
potential differences can be measured. This measurement technique is used for pH, pCO2 and
electrolytes.
Amperometry: The magnitude of an electrical flow of current is proportional to the
concentration of the substance being oxidized or reduced at an electrode. This measurement
technique is used for pO2, glucose and lactic acid.
Conductivity: The specific impedance of a sample as measured by two conducting electrodes
held at a constant voltage is directly proportional to the conductive properties of the sample. This
technique is used for Hct.
6.2 Determination of Test Results
6.2.1 Determination of the Analyte Concentration
The concentration of the analyte is determined with the potentiometric and amperometric sensors.
For both sensors, the analyte concentration is calculated using:
The known analyte concentration of calibrant solution;
The measured voltage or current of the calibrant solution.
The measured voltage or current of the sample.
For potentiometric sensors, the analyte activity in the sample is calculated from the Nerst
equation:
Esample – Ecalibrant = S log (αsample/αcalibrant)
Where E denotes the potential, α denotes the activity of an ion, and S denotes the slope of the
sensor.

6.2.2 Determination of Cell Concentration
Hct
In whole blood, the cellular constituents, red and white blood cells and platelets do not conduct
electricity, while plasma does. For a sample whose electrolyte concentration is given, the more
cells, the less conductivity. The total cell concentration of the whole blood is determined from:
The known value of the electrolyte concentration in the calibrant.
The measured electrolyte concentration of the sample.
The measured conductivity signal generated by the calibrant.
The measured conductivity signal generated by the sample.
CPB
When samples with abnormally low protein levels are tested, the system need to use the CPB
compensation algorithm. The CPB compensation algorithm is specially intended for use when
samples are taken from patients on cardiopulmonary bypass. It also applies to the adult whose
protein levels are abnormally low.

9.3.16 Replacing and Cleaning Needle
Clean L-shape Needle
1.
Check whether L-shape needle has been blocked.
1) Observe whether there are foreign objectives around the internal surface of the needle (in
many cases, the foreign objects will be accumulated in the point of the needle).
2) If the operator can obviously feel the obvious resistance when pulling or pushing the piston
of the syringe, the point of the needle has been blocked by the foreign objects.
2.
If the needle has been blocked, clean the needle as the following procedures:
1) Slowly pull the piston of vacuum pump to the maximum range.
2) Insert the 1mL syringe into the L-shaped needle and then move out the 1mL syringe from the
needle.
3) Quickly push the piston of the vacuum pump to blow out the foreign objects from the
needle.

83.

i15 Blood Gas and Chemistry Analysis System Service Manual
Disassembling the Analyzer
Change the test cartridge’s base assembly
If the L-shaped needle has been blocked heavily, the needle can be changed as the following
procedures:
1.
Disconnect the tubing from the test cartridge’s base assembly.
2.
Remove the spring from the test cartridge’s base assembly.
3.
Connect the tubing into the test cartridge’s base assembly, then apply some AB adhesive on
the joint to prevent air leakage.
Clean Calibrant Fluid Pack’s Needle
1.
Check whether there are foreign objects in the calibrant fluid pack’s needle. If yes, clean the
needle in accordance with Step 5 and Step 6.
2.
As Picture 12 shows, make sure the valve of the calibrant fluid pack is closed.
3.
Use the syringe to aspirate the air. If the piston of the syringe can be moved smoothly, it
proves the distance between the needle and the air valve has not been blocked.
4.
As Picture 13 shows, close air valve by pressing it with hands and then open the valve of
calibrant fluid pack.
5.
Use the syringe to aspirate calibration solutions. If the piston of the syringe can be moved
smoothly and the calibration solutions can be aspirated smoothly, it proves that the distance
between the valve of the calibrant fluid pack and the needle has not been blocked.
6.
As Picture 14 shows, insert 1mL or 2mL syringe into the needle. Quickly pull the piston
outward so that the foreign object can be aspirated out.
NOTE:
After the valve of the calibrant fluid pack has been opened, the calibration solution can only be
aspirated out, or it will be contaminated.
