Thus, for brain saturations both ECMO regimens reached values exceeding 80% of baseline and similar ranges apply for IABP assistance.
For brain saturations, all regimens reached values exceeding 80% of baseline, none of the comparisons between respective treatment approaches differed significantly.
Cerebral oximetry, based on near-infrared spectroscopy (NIRS), provides a measure of brain oxygen saturation.
HBO has no effect on brain oxygen saturation, after HBO treatment.
Bilateral regional brain oxygen saturation (rSO2) trends, reflecting intraoperative brain oxygen imbalance, could warn of brain dysfunction.
The INVOS system was used for real-time monitoring of changes in regional brain oxygen saturation (rSO2) of blood flow in the frontal lobe of the brain (Somanetics Corp., Troy, MI) [ 10].
The objective of this work was to assess the usefulness of monitoring regional brain oxygen saturation (rSO2) in the identification of intraoperative episodes of cerebral ischemia during the surgical clipping of brain aneurysms.
From approximately 3000 mosaic brains and 800 VNCs, we obtained, on average, 28 images of each neuroblast clone in the central brain (reaching saturation; see Supplemental Data) and 6 in the VNC (where we have identified most clones).
Monitoring regional brain oxygen saturation on the operated side is a method hampered by a large percentage of false results, and thus is a monitoring tool of little prognostic value.
Based on multiple indices such as brain tissue O2 saturation, jugular venous oxygen saturation, transcranial Doppler and cerebral microdialysis studies, autoregulation threshold for CPP is thought to be around 50 60 mmHg [46, 47].
