Transcranial Doppler Monitoring of Intracranial Pressure Plateau Waves, Danilo Cardim et al. Transcranial Doppler ultrasonography in neurological surgery and neurocritical care, Robert H. Short-term cerebral monitoring is instrumental during Cerebral Vasomotor Reactivity Testing (VMR), determination of Patent Foramen Ovale with the PFO test (“Bubble Study”), Breath Holding assessment for cerebral reserve, or emboli detection over a selected period of time. While the Dolphin TCD monitoring abilities are designed for long-term monitoring in the Neuro-ICU or the operating room, short-term bilateral monitoring is also available.
Technicians can place event markers or alerts during the monitoring session to better identify and mark various clinical procedures and patient perturbations.

The user-friendly and sophisticated Dolphin monitoring software allows continuous bilateral trending of multiple Doppler parameters, including blood flow velocities, pulsatility indices, and heart rate. For users who are more accustomed to the traditional monitoring headset, the Dolphin TCD equipment offers the dedicated headset with the special quick-lock solution for simple locking of the probes in place.
The advanced Dolphin/XF TCD robotic probe is considered the best TCD robot for cerebral monitoring and clinical assessment, with high speed scanning technology and various other unique features. The Dolphin TCD Machine is ideally designed for optimal and simple TCD cerebral monitoring of bilateral blood flow. The TCD equipment typically includes a dedicated headset or headgear that can hold two TCD probes and manually fix the probes to the monitoring region of the right or left regions of the temporal windows. This diagnosis has clinical value in detecting cerebral vasospasm, doppler monitoring during carotid endarterectomy and carotid endarterectomy stroke, symptomatic carotid stenosis, intraoperative transcranial doppler, intraoperative monitoring, stroke and transient ischemic patients, embolic events, shunt surgery, and more neuro clinical applications. Transcranial doppler TCD monitoring in patients is particularly useful in detecting MCA velocity. It is actually the only modality that allows non-invasive bedside monitoring of cerebral flow. Transcranial Doppler is ideally designed for short-term monitoring and long-term monitoring of MCA velocity. Relative and/or sudden changes in MCA velocity, for example, can become a powerful diagnostic tool and affect the immediate clinical intervention. Monitoring of blood flow in the brain can be critical for the identification of neurological complications. Unilateral monitoring reflects following the changes in the velocity on one side of the brain.īilateral monitoring is the simultaneous measurement of flow on both the right and left sides of the brain, typically the middle cerebral artery and the ipsilateral MCA.ĭuring Transcranial Doppler ultrasonography monitoring in the middle cerebral artery, the focus is on following the trends in velocities over time, timely detection of changes in Intracranial Pressure (ICP), or identifying special events during the monitoring session such as embolic events. Using transcranial doppler is well recognized by many clinical international societies, including the American Heart Association (AHA).Ĭerebral monitoring can be either unilateral or bilateral. TCD Monitoring is an important tool for detecting cerebral ischemia as well as following symptomatic carotid stenosis or monitoring during Carotid Endarterectomy, coronary artery bypass graft surgery (CABG), and other surgeries that require anesthesia.
