Cerebrovascular Reactivity Assessments in Traumatic Brain Injury,. Classically, these metrics have been derived from the intra-cranial pressure (ICP) pulse waveform, in relations to pulsatile changes in arterial blood pressure (ABP) or cerebral perfusion pressure. Recent advancements in signal processing for transcranial Doppler (TCD) flow velocity signals, devel

Transcranial Doppler Protocols and Procedures: Vasomotor Reactivity, It is relatively easy to perform, reliable, safe, inexpensive, and well-tolerated. While there is no significant change in the large vessel diameter with increased PCO2, the arterioles dilate or contract as needed to maintain constant brain blood flow. CO2 inhalation or breath-holding are used to e

Optic Nerve Sheath Diameter for Increased Intracranial Pressure,arrest or brain death. Rapid assessment of intracranial pressure is essential in the diagnosis and management of acute intracranial insults. A recent review of the literature concluded that optic nerve sheath diameter (ONSD) and transcranial Doppler are the most superior non-invasive tools clinicall

Cranial Ultrasound,computed tomography and magnetic resonance imaging. With increasing acuity of critically ill patients placed on supportive devices like continuous renal replacement or extracorporeal therapy that may be high risk for transport for computed tomography, ultrasound use can be a surrogate imaging modali

Applications of Transcranial Doppler Ultrasonography in Sickle Cell Disease, Stroke, and Critical I by identifying those at high risk who benefit from blood transfusion. In this chapter, we will review the literature related to this topic. Beyond SCD, other potential roles for TCD in pediatrics include as a point of care ultrasound (POCUS) or as a neuromonitoring strategy in the pediatric intensi
