Accuracy and Precision of Three Different Methods to Determine Pco2 (Paco2 vs. Petco2 vs. Ptcco2) During Interhospital Ground Transport of Critically Ill and Ventilated Adults

Abstract

During interhospital transport Paco2(IRMA) and Ptcco2 provide the best accuracy when compared with the reference measurement. Patients who either require a tight control of Pco2 or endured lengthy transportation could benefit greatly from the combination of expiratory capnography with mobile arterial blood gas analysis or the transcutaneous measurement of Pco2.

Use of Non-Partitioned Ventilator Tubing Results in Dead-Space Ventilation Hypercarbia

“…6 Capnography, which is cost-effective and is the standard of care in the operating room, has also been adopted, but not widely, in some intensive care units and during patient transport. 7,8 The key component is how to use the information capnography provides. 9 In our patient, if we had used capnography, the high inspired CO 2 level could have been detected early and provided earlier management of the problem.…”

The Revised Digital Transcutaneous PCO2/SpO2 Ear Sensor Is a Reliable Noninvasive Monitoring Tool in Patients After Cardiac Surgery

“…However, sensor preparation, positioning, taping, and the necessity for repeated calibration and repeated changes of the sensor's location because of drifting of the PtcCO 2 signal made handling cumbersome [4]. Additionally, the results of recently performed studies in neonates, infants and adults are controversial in terms of the reliability of these devices [6,[11][12][13]. In adults, clip sensors at the earlobe are routinely used because of its intense capillary perfusion.…”

“…Currently, combined assessment of PtcCO 2 and partial oxygen tension using a single earlobe clip sensor is increasingly used in adult patients during noninvasive mechanical ventilation [5], transportation of critically ill adults [6], bronchoscopy [7], sleep studies [8,9] and pulmonary stress testing [10]. However, sensor preparation, positioning, taping, and the necessity for repeated calibration and repeated changes of the sensor's location because of drifting of the PtcCO 2 signal made handling cumbersome [4].…”
