Thermal Control; Barometric Pressure Sensor; Cartridge Test Cycle - Abbott i-STAT 1 System Manual

Infrared
The Infrared Communication Window provides the analyzer with two-way
Communication communication to the Central Data Station via a Downloader, allows analyzer-
Window to-analyzer software updates, and allows analyzer-to-printer communication for
printing.

Thermal Control

The analyzer contains a thermal control subsystem of thermistors and heating
contact wires that controls the temperature of the sensors and fluids that come
into contact with the sensors to 37°C. This subsystem is activated automatically
when a cartridge containing tests which require thermal control at 37°C is inserted
into the analyzer.
Barometric Pressure
The analyzer contains a solid-state barometric pressure sensor, which determines
Sensor the ambient atmospheric pressure used for the PO

Cartridge Test Cycle

An operator starts a cartridge test cycle either by inserting a cartridge into the
analyzer or by selecting the i-STAT Cartridge option from the Test or Quality Tests
Menu.
