1 INTRODUCTION
1.1 Intended Use
The OPTI ™ CCA-TS Critical Care Analyzer is intended to be used for the measurement of
hydrogen ion concentration (pH), carbon dioxide partial pressure ( P CO
2
), oxygen partial pressure
( P O
2
), sodium (Na
+
), potassium (K
+
), ionized calcium (Ca
++
), chloride (Cl
-
), glucose (Glu), blood
urea nitrogen (BUN/urea), lactate (Lac), total hemoglobin concentration (tHb) and hemoglobin
oxygen saturation ( S O
2
) in samples of whole blood, and pH, sodium, potassium, ionized calcium,
chloride, glucose and BUN (urea) in serum and plasma, in either a traditional blood gas, clinical
laboratory setting or point-of-care locations by personnel minimally qualified to perform and
report these results.
The table below provides important information regarding supported sample types, available
reporting units and analyzer measurement ranges for each parameter.

1.2 Principles of Operation
The OPTI CCA-TS is a microprocessor-controlled medical instrument measuring optical
fluorescence from discrete sensors called optical electrodes (optodes).
A disposable, single-use cassette contains all of the elements needed for calibration, sample
measurement and waste containment. Specific calibration information from the cassette is
scanned into the analyzer by holding the cassette package in front of the bar code scanner.
The cassette is then placed into the measurement chamber.
The analyzer warms the cassette to 37.0 ± 0.1 °C (98.6 ± 0.1 °F), and performs a calibration
verification on the sensors for P CO
2
and P O
2
by passing a precision calibration gas mixture
across the optode sensors. The pH and electrolyte channels are calibrated with precision buffer
solution contained in the cassette. The tHb and S O
2
channels are factory-calibrated.
