Ankle and Toe Pressure (ATP) Kit Guide

Assemble the Tubing

  • When you first get your ATP Kit if you want to use the toe pressure component you will need to assemble that piece.
  • Please insert the batteries in the Doppler. They may need charging for the first use (if using rechargeable batteries).

Testing the Patient - Toe Pressure

This video is about 2 minutes long; below are step by step instructions.


Step by Step Instructions

Patient Testing - Toe Pressure

Place Toe Cuff and PPG Sensor

Once you have the Dopplex PPG system connected. The next two steps are taping the PPG sensor to the toe, and wrapping the toe cuff.

The hole in the strip goes over the protrusion on the PPG sensor.

Wrap the toe; the black side should face the skin.

When securing the toe sensor make sure it is not applied too tight, as well too loose is also a problem.

Start Doppler - wait for Waveform

Power on the DMX and wait for the signal to appear and stabilize.

Pump up Toe Cuff

Increase the pressure in the toe cuff to progressively restrict blood flow.

Images below of what the screen will look like.

Your headphones should always look amazing! Pick your preferred color.

Start pumping; after a screen of normal waveforms


As you pump the trace will go flat (blood flow is cut off)


This shows blood flow is completely restricted. (20-30mmHg above systolic)

Release pressure - controlled; using the built in indicator

Release pressure being guided by keeping the white bar in the green band.

Identification of Systolic Pressure

The system will identify systolic pressure.
If the identification line is not positioned where the waveform indicates pulsations returned, you may adjust the "white marking line" by using the arrows at the left and right.

As you move the line, the systolic pressure will change.

The "green" check mark is used to move to the next step.

Release all Pressure

Use the trigger to release all pressure.

Patient Testing - Standard ABI - Arms and Ankles

Testing the Brachial Systolic Pressure

The standard ABI traditionally starts with testing the brachial systolic pressures of both arms. The higher of the two brachial systolic pressures is used in the calculation.

Testing the Other Brachial Systolic Pressure

Step by Step Instructions

Testing the Ankle - Dorsalis Pedis

Testing the Ankle - Posterior Tibial Artery

The higher of the two readings between the Dorsalis Pedis and Posterior Tibial Artery is used for the calculation.
