Abstract:
Transcranial Doppler ultrasonography is the only non invasive examination enabling the reliable measurement of the blood flow velocity in the intracranial arterial trunks. However, it cannot be constantly perfect. It is fully realized in about 10% of the patient. Even incomplete it remains a useful complementary exploration in the management of the cerebral vascular disease.

01:19Assessing Blood pressure using a doppler ultrasound
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Direct Method
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...
