title: Assessment of a bubble tonometer as a quality control system for blood gas analyzers (PO2 and PCO2).
abstract: A blood gas tonometer device, comprising an accurate gas mixer (Corning 192) associated with a dual channel bubble tonometer (Corning 184) was tested for reliability, accuracy and ease of use as a quality control system for pO2 and PCO2 blood gas analyzers. From our results it is apparent that this system can be used instead of older and more bulky tonometry devices, gas mixing systems or cylinders of fixed composition.
