The OPTI CCA analyzer is a microprocessor-based instrument that measures 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° ±0.1°C (98.6° ±0.1°F), and 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.

OPTI CCA-TS Single Use Patient Cassette Features:

• Room temperature storage eliminates time consuming equilibration, logistics and storage issues
• Calibration of cassette before sampling eliminates losing sample if cassette calibration fails
• Long cassette shelf life of 6-8 months from the date of manufacture
• Easy and safe to maintain
• Waste is locked in the cassette for safe disposal
• No electrodes provides maintenance-free operation
• No reagents for zero standby cost
