The purpose of this study was to evaluate and report on the Gas-STAP™ continuous blood gas and pH monitoring system. This system was tested for accuracy, stability and reproducibility during extracorporeal circulation when compared to intermittent blood gas sampling. The Gas-STAT was used in conjunction with 44 clinical cardiopulmonary bypass procedures. There were 261 arterial and 259 venous blood samples obtained for analysis.
Early results comparing Gas-STAT versus intermittent samples analyzed on an IL813 blood gas analyserb showed less than ideal correlation. With continued clinical experience and further system refinements, data agreement improved substantially. This system provides valuable information to the perfusion team. Continuous blood gas and pH readings give the perfusionist immediate visualization of the effects of therapeutic interventions. Changes in gas flows and mixtures, blood flow, perfusate temperatures, hemodilution and the effects of pharmacologic agents all can affect the acid base and blood gas status of the patient. This system can be calibrated and employed without any substantial increase in time required by the perfusionist.
Key words: Gas-STAT™ / continuous blood gas/pH monitoring / blood gas/pH / monitoring accuracy
