Dolphin TCD Machines for Brain Death Assessment – Available at MedTech Edge for AU & NZ
25 July 2025
MedTech Edge supplies Dolphin TCD machines in Australia and New Zealand, supporting fast and reliable brain death assessment for healthcare professionals.
Transcranial Doppler (TCD) technology is now an essential tool in neurocritical care, allowing clinicians a non-invasive way to assess cerebral blood flow. Dolphin TCD machines stand out among available solutions, delivering trusted, rapid brain death assessment to support vital clinical decisions in acute care. With advanced automation and established reliability, Dolphin TCD systems represent a benchmark in neurological diagnostics and are now utilised in neurocritical care, supported by MedTech Edge, throughout Australia and New Zealand.
What Is Brain Death Assessment and Why Is Speed Crucial?
Brain death assessment is a vital procedure in clinical and emergency contexts, used to definitively determine the irreversible loss of all brain function. This process is especially critical in ICUs, emergency departments, and neurology units, where fast, accurate diagnostics enable timely decisions and effective patient management. Leveraging technologies like TCD and transcranial Doppler systems allows clinicians to conduct brain death assessments efficiently, minimising delays and supporting urgent care workflows.
Speed and accuracy in brain death diagnosis matter because they:
• Enable prompt identification of organ donation candidates.
• Ensure legal criteria and complete medical documentation are met.
• Minimise uncertainty for families and offer clarity to care teams.
• Optimise the use of critical care resources.
• Align with national and international clinical standards and guidelines.
Role of TCD in Brain Death Diagnosis
Transcranial Doppler (TCD) ultrasound is a non-invasive, bedside method for measuring cerebral blood flow, using ultrasonic waves through the skull to gauge blood velocity in the brain’s main arteries. TCD gives clinicians a quick, real-time view of cerebral circulation, making it invaluable for brain death assessment.
Compared to ancillary techniques like EEG and CT angiography, TCD offers several advantages for intensive care and emergency settings:
• Delivers immediate, real-time bedside results
• Involves no radiation, contrast agents, or sedation
• Portable and usable in any clinical location
• Enables repeat assessments as patient condition changes
The Australian and New Zealand Intensive Care Society (ANZICS) Statement on Death and Organ Donation (Edition 4, 2019) recognises TCD as a valuable screening tool. According to the ANZICS guidelines, TCD helps determine the best timing for confirmatory brain perfusion imaging, reducing unnecessary procedures and streamlining care.
