Evaluation of capnography to predict arterial PCO 2 in neurosurgical patients

J Neurosurg Anesthesiol. 1992 Oct;4(4):241-4. doi: 10.1097/00008506-199210000-00002.


This study was designed to see if capnography could be used to predict PaCO 2 so as to adjust ventilation to maintain PaCO 2 within the desired range in head-injured patients undergoing prolonged mechanical ventilation. It was further designed to see if P ETCO 2 could accurately predict PaCO 2 based on only one arterial blood gas (ABG) measurement or if more frequent, i.e., daily, ABG measurements were required.
