Vascular Technologists or vascular sonographers assist physicians in the diagnosis of disorders affecting the circulation. They use ultrasound equipment to record vascular blood flow, blood pressure, limb volume changes, and oxygen saturation. These tests are generally performed during or immediately after surgery.
Vascular technologists complete patients’ medical history, evaluate pulses and assess blood flow in arteries and veins by listening to the vascular flow sounds for abnormalities, and assure the appropriate vascular test has been ordered. Then they perform a noninvasive procedure using ultrasound instruments to record vascular information such as vascular blood flow, blood pressure, oxygen saturation, cerebral circulation, peripheral circulation, and abdominal circulation.
Vascular technologists provide a summary of findings to the physician to aid in patient diagnosis and management.
