| Abstract: | Purpose Cerebral tissue oxygenation (PbrO2) is most frequently monitored using a Licox CC1.SB system (LX, Integra Neuroscience, France) but recently a new probe—the Neurovent-PTO (NV)—was introduced by a different manufacturer (Raumedic, Germany). There are no prospective data on how these probes compare in clinical routine. We therefore compared both probes in comatose patients suffering from traumatic brain injury (TBI) or subarachnoid haemorrhage (SAH) during dynamic changes of inspirational oxygen fraction (FiO2) and mean arterial pressure (MAP). |
