Technology—Principles of operation


The OPTI® CCA/CCA-TS  Blood Gas and Electrolyte Analyzers are microprocessor-based instruments that measure optical fluorescence from discreet 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 read into the analyzer by swiping the cassette package through the bar-code reader. The cassette is then placed into the measurement chamber.


The analyzer warms the cassette to 37.0°C (±0.1°C)/98.6°F (±0.1°F), and it performs a calibration verification on the sensors for PCO2 and PO2 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. When calibration is verified, the analyzer aspirates the blood sample into the cassette and across the optode sensors. After equilibrating with the blood sample, fluorescence emission is then measured.


The OPTI CCA/CCA-TS single-use patient cassette includes these features:

Calibration of cassette before sampling—eliminates losing sample if cassette calibration fails
Long cassette shelf life—6–12 months from the date of manufacture
Easy and safe maintenance
Safe disposal—waste is locked in the cassette
Maintenance-free operation—no electrodes
Zero standby cost—no reagents required
