77617-9
ClinicalToe brachial index - left
Definition
The reading is derived in order to determine the severity of peripheral arterial disease present in a lower extremity. The test is performed using a small blood pressure cuff that is fitted around a toe along with a photoplethysmograph (PPG) infrared light sensor. The resultant toe brachial index (TBI) is generated using the systolic blood pressure readings from the arm and toe.
