Best Results

For best results, ampules, cartridges and handhelds should be at the same
temperature.
Ampule Use
When using cartridges that contain sensors for pH, PCO
separate ampule must be used for each cartridge being tested.
Do not use residual TriControls solution that may be in a syringe, ampule or capillary
tube for additional testing of cartridges that contain sensors for ionized calcium, pH,
PCO , or PO . However, cartridges without these sensors may be tested with remaining

fluids if that testing is performed within 10 minutes of opening the ampule.
Before Use
i-STAT TriControls solutions require different temperature stabilization times depending
on whether or not PO
ampule to room temperature for 4 hours prior to use. If PO
equilibrate the ampule for approximately 30 minutes at room temperature.
Procedure
STEP
1 Access the Control option under Quality Tests in the
Administration Menu. Enter the required information. The
handheld allows 15 minutes (or the customized timeout) to
insert the cartridge after the last data entry.
2 Immediately before use, shake the ampule vigorously for 5 to
10 seconds to equilibrate the liquid and gas phases.
To shake, hold the ampule at the tip and bottom with forefinger
and thumb to minimize increasing the temperature of the
solution. If necessary, tap the tip of the ampule to send
solution back into the bottom section of the ampule.
3 Protect fingers with gauze, tissue or glove, or use an ampule
breaker to snap off the tip of the ampule at the neck.
4 Immediately transfer the solution from the ampule into a
capillary tube or syringe, and then immediately transfer the
solution into a cartridge.
5 Immediately seal the cartridge and insert it into a handheld – it
is important not to expose the solution to room air since this
will alter the results.
Note: Since aqueous based solutions such as control
materials lack the buffering capability of whole blood,
the transfer process from ampule to cartridge must be
more expedient than with a patient sample.
