RESULTS
Calculations
The i-STAT handheld contains a microprocessor that performs all calculations required for reporting results.
Displayed Results
Results are displayed numerically with their units. Electrolyte, chemistry and hematocrit results are also depicted as bar
graphs with reference ranges marked under the graphs.
Suppressed Results
There are three conditions under which the i-STAT System will not display results:
1. Results outside the System’s reportable ranges are flagged with a
<
or
>
, indicating that the result is below the lower
limit or above the upper limit of the reportable range respectively. (See the table of Reportable Ranges.) The
< >
flag
indicates that the results for this test were dependant on the result of a test flagged as either
>
or
<
.
Action:
Send specimen(s) to the laboratory for analysis, if necessary.
2. Cartridge results which are not reportable based on internal QC rejection criteria are flagged with
***
.
Action:
Analyze the specimen again using a fresh sample and another cartridge. If the specimen integrity is not in question, the
results that are not suppressed should be reported in the usual manner. If the result is suppressed again, send
specimen(s) to the laboratory for analysis in accordance with the Laboratory Procedure Manual.
3. A Quality Check message will be reported instead of results if the handheld detects a problem with the sample, calibrant
solution, sensors, or mechanical or electrical functions of the handheld during the test cycle.
Action:
Take the action displayed with the message that identifies the problem. Refer to the i-STAT or i-STAT 1 System
Manual’s Troubleshooting section or the “Analyzer Coded Messages” Technical Bulletin if necessary.
Printing and Transmitting Results
Printing Results from the i-STAT Portable Clinical Analyzer to the HP Portable Printer
1. Place the handheld in the cradle of an IR Link or align the IR windows of the handheld and printer. Turn the printer on
(printer light red) or press the paper advance switch to reactivate.
2. To print the displayed test record, press the PRT key on the handheld.
3. To print a stored test record(s), select “Print Results” from the Stored Results menu. Select records to be printed by
pressing the Key(s) corresponding to the numbers beside the record(s). Press the numbered key again to deselect a
record. Then press the PRT Key.
4. Do not move the handheld while “Printing” is displayed.
Optional:
Write the patient’s name on the “Pt Name” line and the physician’s name on the “Physician” line.
Note:
Results printed on thermal paper will fade with time and are therefore not acceptable as a permanent
chartable record
.
