When“Start”isselected,theVENDYS test will begin.
Thetemperature probeswill begin to measure thefingertiptemperature and the
applicationwill determine the temperature stability based onthe input value fromthe
TestSetup form. Once the fingertiptemperaturestabilizes, theocclusion cuffwill
inflate totheselectedsupra-systolic increment.The cuff inflatesinabout 4seconds,
andthepatient’sfinger temperatureshould begin to decline in about 30 seconds.

There are three phasesofthe test. During thefirststabilizationsection, the linesfor
both hands should displayastable,flat baseline. Inthe followingocclusionsection, the
red line for theright hand should displayalinear temperature drop, while the blue
(left hand)line should remainstable. Inthe third section, the red line should showa
quickreturn to the baseline temperature after occlusion.
