Principle of operation
3.1
Introduction
The
SysToe
inflates the occlusion cuff up to the preset occlusion pressure.
Then, it deflates the occlusion cuff slowly until the pressure in the cuff
reaches 10 mmHg.
The pressure in the cuff and the PPG (Photo PlethysmoGraphy) signal are
recorded during deflation. The pressure at the time of resumption of arterial
inflow is the systolic pressure.
Resumption of arterial inflow is detected by the PPG sensor.
