Review[Applications of the determination of brain tissue oxygen pressure (PtiO2)].
We review the basic aspects concerning the technique of measurement of partial brain tissue oxygenation (PtiO2) monitoring, and its indications in neurological patients. ⋯ Monitoring the PtiO2 of focal brain tissue is a safe and reliable method for regulating cerebral oxygenation. PtiO2 monitoring has some advantages over other established methods such as near infra red spectroscopy and SjO2 monitoring: 1) recalibration is not necessary, and 2) once inserted, it allows valid and stable measurement lasting hours and even days.
