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