The regional air PCO2 (aPrCO2) showed good agreement with the steady-state saline regional PCO2 (ssPrCO2). Intraperitoneal measurements may be an alternative method of monitoring intestinal perfusion after abdominal surgery.

The care and handling of the animals was in accordance with legislation by the Swedish Board of Agriculture.

In contrast to the results of previous investigations, the sigmoid colonic pulse oximetry was not useful because the method proved to be overly sensitive and non-linear in relation to regional blood flow.

In this experimental model of aortic crossclamping, continuous CSF oxygen tension monitoring allows rapid detection of alterations in spinal cord circulation.
