Art: 723270-00A Rev. Date: 20-Apr-12
The ranges for i-STAT aqueous control solutions are established for the degree of
oxygen equilibration that occurs in cartridges tested at or near sea level. PO
2
results
for aqueous solutions, including i-STAT controls and Calibration Verification Set and
proficiency (external quality control) samples, can be corrected for higher altitude
environments using the following equations. Observed PO
2
values should be corrected
before comparing them to the values on the Value Assignment Sheet posted on the
APOC website at www.abbottpointofcare.com.
Equations:
For PO
2
values below 150 mmHg:
PO
2
corrected = PO
2
observed + (0.067 x (760 – BP))
Where BP is the barometric pressure reading from the Analyzer Status
screen.
(Approximate change: For every decrease of 15 mmHg in pressure from 760
mmHg, add 1 mmHg to the observed value.)
For PO
2
values above 150 mmHg:
PO
2
corrected = PO
2
observed + (0.029 x (760 – BP))
Where BP is the barometric pressure reading from the Analyzer Status
screen.
(Approximate change: For every decrease of 35 mmHg in pressure from 760
mmHg, add 1 mmHg to the observed value.)
CALIBRATION VERIFICATION FOR BLOOD GAS/ ELECTROLYTE/ METABOLITE
CARTRIDGES (i-STAT TRICONTROLS)
Purpose
Calibration Verification is a procedure intended to verify the accuracy of results over
the entire measurement range of a test. The performance of this procedure at defined
intervals may be required by regulatory accreditation bodies. While the Calibration
Verification Set contains five levels, verification of the measurement range could be
accomplished using the lowest, highest and mid levels.
Overview of Procedure
It is recommended that each sensor type be included in the Calibration Verification
procedure using a selection of handhelds that have passed the Electronic Simulator
check. See Technical Bulletin “Calibration Verification and the i-STAT System” for more
information.
Calibration Verification Solutions for Cartridges
A five-level Calibration Verification Set is available to verify the calibration of i-STAT
cartridges throughout the reportable ranges for:
Sodium PCO

Glucose
Potassium PO

Lactate
Chloride TCO

BUN/Urea
Ionized Calcium Hematocrit Creatinine
