What is an intraparenchymal monitor?
What is an intraparenchymal monitor?
A variety of intraparenchymal monitoring devices have been. used for several years to monitor intracranial pressure (ICP) and more recently for measuring cerebral oxygenation and. temperature in patients with traumatic brain injury (TBI) and. subarachnoid haemorrhage (SAH).
What does an ICP monitor do?
Intracranial pressure (ICP) monitoring is a diagnostic test that helps your doctors determine if high or low cerebrospinal fluid (CSF) pressure is causing your symptoms. The test measures the pressure in your head directly using a small pressure-sensitive probe that is inserted through the skull.
What is a Codman monitor?
Introduction: The Codman MicrosensorTM measures intracranial pressure via a strain gauge microchip located at the tip of the catheter. Pressure is reflected as an electrical voltage that is transmitted to the proximal end of the catheter through nylon encapsulated copper wires.
What’s Cushing’s triad?
The Cushing reflex (vasopressor response, Cushing reaction, Cushing effect, and Cushing phenomenon) is a physiological nervous system response to acute elevations of intracranial pressure (ICP), resulting in Cushing’s triad of widened pulse pressure (increasing systolic, decreasing diastolic), bradycardia, and …
What is normal ICP?
For the purpose of this article, normal adult ICP is defined as 5 to 15 mm Hg (7.5–20 cm H2O). ICP values of 20 to 30 mm Hg represent mild intracranial hypertension; however, when a temporal mass lesion is present, herniation can occur with ICP values less than 20 mm Hg [5].
When do you remove ICP monitor?
The ICP monitoring devices get removed once the ICP is normalized with sustained or improved clinical neurology (motor score at least 5) for at least 48 to 72 hours without the use of any interventions.
What are the symptoms of intracranial pressure?
These are the most common symptoms of increased ICP:
- Headache.
- Blurred vision.
- Confusion.
- High blood pressure.
- Shallow breathing.
- Vomiting.
- Changes in your behavior.
- Weakness or problems with moving or talking.
What is Licox?
The Licox® Brain Oxygen Monitoring System measures intracranial oxygen and temperature and is intended as an adjunct monitor of trends of these parameters, indicating the perfusion status of cerebral tissue local to sensor placement.
How do you zero a ICP Transducer?
Zeroing
- The ICP only requires ‘zeroing’ if requested by the Codman™ monitor.
- Codman™ monitor should be connected to the Phillips™ monitor via the ICP monitor cable into the transducer.
- Turn the Codman™ monitor on and press ‘0’
- On the Phillips™ monitor, press the ‘Zero’ button.
When to use an intracranial pressure monitor?
Invasive intracranial-pressure monitoring is often used in patients with suspected increases in intracranial pressure, especially those with traumatic brain injury.

How does displacement of brain parenchyma cause ICP?
Substantial displacement of brain parenchyma may cause elevation of intracranial pressure (ICP) and potentially fatal herniation syndromes . Clinical manifestations of intraparenchymal hemorrhage are determined by the size and location of hemorrhage, but may include the following:
How is an intraparenchymal drainage catheter inserted?
Figure 1.01: Insertion of an intraparenchymal catheter. This catheter is similar to a conventional fluid filled ventricular drainage catheter.
What are the clinical manifestations of intraparenchymal hemorrhage?
Clinical manifestations of intraparenchymal hemorrhage are determined by the size and location of hemorrhage, but may include the following: Lobar – Contralateral hemiparesis or sensory loss, contralateral conjugate gaze paresis, homonymous hemianopia, abulia, aphasia, neglect, or apraxia
