The TM-ABI system is indicated for use on adult subjects at risk of having or developing peripheral arterial disease(PAD).
TM-ABI system is intended for the rapid measurement of ankle-brachial pressure index (ABPI), or ankle-brachial index(ABI), and pulse volume recording (PVR)/ volume plethysmography in adults.
It is suitable for use in wound care assessment, for assessing symptomatic PAD, and as a screening device for PAD. It may also be used on patients with venous or arterial ulcers prior to the application of compression therapy.
The TM-ABI is based on volume plethysmography at brachial and ankles.
The blood pressure on the upper and lower extremities is measured simultaneously, resulting in the calculation of the ankle-brachial index (ABI).
A toe sensor assess the dorsalis pedis arteries and calculate the Toe Brachial Index (TBI).
The volume plethysmography analysis at the arm provides the peripheral Augmentation Index (pAIx) Which is a marker of aortic stiffness and allows us to calculate Central Aortic Systolic Pressure (CASP).
The volume of plethysmography analysis at the arm and ankles provides the brachial ankle Pulse Wave Velocity (baPWV) which is a marker of lower extremity artery stiffness.
