Abstract:
Monitoring intracranial pressure (ICP) is important in a variety of neurologic conditions, including aneurysmal subarachnoid hemorrhage and traumatic brain injury. Monitoring and controlling ICP can mitigate secondary injury of the brain. Of the invasive methods of monitoring ICP, the external ventricular drain is still considered the gold standard. However, microtransducers have been shown to be a reliable option with significantly lower risks of complications. Due to their reproducibility, and their limitations, they are not ready to replace invasive ICP monitoring techniques. This article reviews the commonly used invasive and non-invasive methods of monitoring ICP.

This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
