§ 868.1150 Indwelling blood carbon dioxide partial pressure (P 2 CO2 ) analyzer. (a) Identification. An indwelling blood carbon dioxide partial pressure P CO2 analyzer is a device that consists of a catheter-tip P CO2 transducer (e.g., P CO2 electrode) and that is used to measure, in vivo, the partial pressure of carbon dioxide in blood to aid in determining the patient's circulatory, ventilatory, and metabolic status. (b) Classification. Class II (special controls). The special control for this device is FDA's “Class II Special Controls Guidance Document: Indwelling Blood Gas Analyzers; Final Guidance for Industry and FDA.” [47 FR 31142, July 16, 1982; 47 FR 40410, Sept. 14, 1982, as amended at 52 FR 17735, May 11, 1987; 66 FR 57368, Nov. 15, 2001]
