Telemetric ICP Measurement

Indications of Telemetric ICP Measurement

In addition to using catheters to measure intracranial pressure for acute indications, it may, depending on the clinical assessment, also be necessary to measure the ICP (intracranial pressure) for an extended period. One specific indication for longer pressure measurement is hydrocephalus. Hydrocephalus occurs when the production and absorption of CSF (cerebrosoinal fluid) is unbalanced.

In order to monitor the symptoms in hydrocephalus patients with a conventional catheter, the patient must remain in bed. This is a significant disadvantage for the study of hydrocephalus. Monitoring the ICP while the hydrocephalus patient is moving and changing her/his position provides important insights for the treatment of the symptoms.

Information about the ICP is crucial for treating hydrocephalus successfully and sustainably. It will be the decision-making basis for the type of therapy to be applied. For example, whether a patient needs a shunt valve, or how to best adjust the shunt valve for draining the CSF. Both too much and too little drainage should be avoided.

By evaluating the patient’s ICP during various activities the shunt valve can be optimally adjusted to the patient's requirements, which significantly reduces the number of procedures on the patient's shunt valve.

Noninvasive ICP Measuring

RAUMEDIC has developed an innovative and unique system based on telemetry, which offers an alternative to traditional cable bound ICP monitoring catheters which connect to a monitor. The telemetric pressure catheter NEUROVENT-P-tel is fully implanted below the scalp on the cranial bone and collects ICP measurements in the parenchyma.

The telemetric system measures the ICP using microchip technology which transfers the pressure values cable-free to a reader (Reader TDT readP) through the closed scalp using validated RFID principles. The data is captured and stored on the RAUMEDIC MPR 1 DATALOGGER. The light-weight and practical device does not limit the patient’s mobility.
