Chapter 5 Patient Analyzing
NOTE:
Take safety measures when working with biological samples, such as wearing
approved gloves, etc.
5.1 Sample Collection and Preparation
5.1.1 Sample Collection
Blood samples should be collected according to proper medical guidelines containing collection
details, such as site selection, collection procedures, sampling devices, sample handling, etc.
Sterile techniques should be followed to prevent the site from being contaminated.
Handle blood samples and collection devices with care, and wear approved protective
gloves to avoid direct contact with samples.
WARNING
NOTE:
Only fresh whole blood samples are recommended for use.
When taken for electrolyte analysis, venous samples should not be collected from a
central venous catheter containing silver sulfadiazine or chlorhexidine, because they
have a great influence on sodium levels.
Samples should be collected by trained professionals.
For mixed venous samples, the system reports only pO2 result.
5.1.2 Anticoagulants
Only those sample devices containing the proper amount of calcium-titrated (balanced) heparin or
lithium heparin as the anticoagulant should be used to collect whole blood samples. If
calcium-titrated (balanced) heparin is used as an anticoagulant, the minimum heparin-to-blood
ratio should be 2.3 units of heparin per 1.0mL of blood sample. If a sample is analyzed for
ionized calcium, the maximum heparin-to-blood ratio should be 15 units of heparin per 1.0mL of
blood sample; if not, the maximum heparin-to-blood ratio should be 50 units of heparin per
1.0mL of blood sample.
If there are clots in the blood sample, discard it and collect samples again.
CAUTION
i15 Blood Gas and Chemistry Analysis System User Manual Patient Analyzing
- 55 -
NOTE:
Dont use the following anticoagulants: EDTA, citrate, and oxalate, because they have a
great influence on test results for pH and electrolytes.
5.1.3 Collection Devices and Volume
Samples can be introduced into the system with the following devices: syringes and capillary
tubes. It is recommended that VITREX® Blood Gas Capillary Tubes with a minimum volume,
filled of 175μL (Article Number: 182413) should be used.
NOTE:
The system uses 110μL samples for analysis, and make sure it can aspirate enough
sample.
The minimum fill volume for a 1mL syringe is 200μL.
The minimum fill volume for a 2mL syringe is 800μL.
The minimum fill volume for a 5mL syringe is 1.5mL.
Dislodge bubbles from the syringe, and cover it as soon as the sample is collected.
Cork should never be used to cover the syringe.
A capillary tube should be filled to capacity and covered securely. Cork or clay should
never be used to cover the capillary tube.
5.1.4 Notes
Follow the notes below to ensure that test results are accurate:
1. Cover the sample device immediately after collection to prevent it from being
contaminated by air.
2. Mix blood samples thoroughly prior to sample introduction.
3. Make sure there are no clots in blood samples, or else the results will be inaccurate.
4. Perform the sample test immediately after its collection to get the most accurate
results. Measure samples for blood gases and Ca++ within 10 minutes, and measure
samples for other analytes within 30 minutes.
5. Used sample devices are biohazardous waste, and should be handled abiding by
local regulatory guidelines.

Controls should be stored at 2 - 8°C (avoid freezing) with the relative humidity of 25% - 93%
(non-condensing).
Controls should be used at 10 - 31°C with the relative humidity of 25% - 80% (non-condensing).
Before Use
Controls should be equilibrated to room temperature before use. If oxygen is to be measured, the
ampoule needs to stand at room temperature for 4 hours. If not, the ampoule needs to stand at
room temperature for only about 30 minutes.
Immediately before use, mix controls completely by shaking the ampoule gently, and always hold
an ampoule at tip and at bottom with forefinger and thumb to minimize increasing controls
temperature. Tap the tip of the ampoule carefully with your fingernail to remove any solution.
NOTE:
Store and use controls according to the user manual, and use them before the
expiration date as labeled on the package.
Only controls provided by EDAN or its authorized distributors should be used.
For test cartridges with pH, pCO2, pO2, Ca++ sensors, a new ampoule and syringe or
capillary tube should be used for each test. For test cartridges without pH, pCO2, pO2,
Ca++ sensors, the remaining solution can still be used if the ampoule is opened within
10 minutes.
The test results should fall within the acceptable ranges programmed in the bar code
on the user manual for controls provided by EDAN.

Chapter 11 Theory
The system utilizes the electrochemical method to determine the concentrations of blood gases
and blood chemistries, and utilizes the conductivity method 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.
11.1 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 User Manual Theory
- 119 -
Potentiometric Sensor
Amperometric Sensor
Conductometric Sensor
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.
11.2 Determination of Test Results
11.2.1 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:
1) The known analyte concentration of calibrant solution;
2) The measured voltage or current of the calibrant solution.
3) 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.
i15 Blood Gas and Chemistry Analysis System User Manual Theory
- 120 -
11.2.2 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:
1) The known value of the electrolyte concentration in the calibrant.
2) The measured electrolyte concentration of the sample.
3) The measured conductivity signal generated by the calibrant.
4) 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.
