The Systoe Toe Pressure Measurement Device- How Do You Use It?

Over the years, Ankle-Brachial Index (ABI) medical has been used by medical practitioners to diagnose Peripheral Artery Disease (PAD) in the legs. The health practitioners get this result by dividing the blood pressure of the ankle’s artery with that of the arm’s artery. Here, if the ratio is less than 0.9, it is safe to say that the person has PAD which is a convenient way to diagnose the disease.

However, there are cases where the method has proven to be ineffective in measurement for the diagnosis of PAD due to hindrance, necessitating the introduction and embracement of the systoe toe pressure measurement to help measure and produce the Toe Brachial Index(TBI). These situations include :

Diabetic patients- These patients often have abnormally high Ankle-brachial Index due to atherosclerosis that leads to plaque and calcification of the leg’s arteries.
Old patients- Medial calcification tends to occur in the personal arteries due to age.
Renal failure Patients- The effects of these underlying conditions make it difficult to measure the pressure using ABI accurately.

Systoe Toe Pressure Measurement System Explained

For several reasons, mainly because the toe arteries get affected by the calcium deposition that hinders measurement later in the stages, toe systolic pressure is a more productive way that practitioners can use to outmaneuver the relevant limitations.

The Systoe Toe Pressure Measurement device is a technologically advanced non-invasive device used to measure systolic toe pressure using infrared photoplethysmography (PPG). The machine uses photoelectric cells to determine skin blood volume changes via a unique algorithm obtained from the measurements. Healthcare practitioners can also use the device to measure systolic finger pressure as a procedure in arteriovenous (AV) graft or fistula assessment.


How to use the Systoe


The greatest advantage of using his machine is its ease of use and user-friendliness. The machine is battery-powered and lightweight; hence it can be carried around. To use the equipment effectively, follow the following steps :

Ensure the machine is functional with a charged battery.
Fit the occlusion cuff on the proximal phalanx of the patient’s finger or toe
Place the sensor together with the cuff.
Press the start button on the machine once you are ready to collect the readings. The cuff will then automatically begin to inflate and then deflate accordingly.
Observe the display and evaluate the blood pressure displayed on the machine as it provides accurate results. It is worth noting that the device is highly beneficial as it measures blood pressures as low as 20mmHg.

How to calculate the Toe-Brachial Index

To get the TBI, you need to divide the systolic toe pressure with the systolic brachial pressure. The normal TBI should be averagely higher than 0.7; any value below that indicates an underlying disease.


The Systoe is a highly effective means that is very important in diagnosing the PAD regardless of problems such as a clot, cholesterol, or medial calcification hindering the process. The process is quite simple and can be around by a vast variety of medical practitioners as it involves placing the cuff appropriately on the toe, pressing the start button, reading the results on the display as the cuff automatically inflates and deflates, and analyzing them later to get the outcome you require.
