Measurement of Oxygen Partial Pressure in the Brain

After primary cerebral damage to the brain caused by a traumatic event, there is a high risk of secondary damage to the brain tissue. One of the main causes is cerebral oxygen deficiency. In most patients, the elevated ICP (intracranial pressure) negatively impacts cerebral perfusion and can therefore cause cerebral ischemia. This temporary or permanent disproportion between the brain tissue's oxygen supply and oxygen demand can cause tissue damage and possible necrosis.

The RAUMEDIC NEUROVENT-PTO catheter provides information for three parameters: the ICP (intracranial pressure), the temperature, and the oxygen partial pressure, all in one catheter.

The NEUROVENT-PTO 2L provides the ability to measure ICP, oxygen partial pressure and temperature through a single catheter. The NEUROVENT-PTO 2L catheter can be implanted by tunneling using Spliceable Tunneling Sleeve CH8 or by BOLT using BOLT KIT PTO 2L.

Depending on the indication, it is also possible to use the NEUROVENT-TO catheter to measure the temperature and oxygen partial pressure in brain tissue.

In addition to the general advantages of the RAUMEDIC catheters NEUROVENT-PTO and NEUROVENT-TO, oxygen sensors do not change oxygen content during the measurement of the oxygen partial pressure. Documentation and data storage of the oxygen measurement values is accomplished easily and reliably at any time using RAUMEDIC's data acquisition device MPR2 logO DATALOGGER.
