Operational Overview: Phases of the Measurement Cycle


temp perf thing


There are 3 phases of the measurement cycle:

  • Temperature Stabilization
  • tissue Calibration and
  • Perfusion Measurement

The BPM automatically cycles through these phases of measurement.

Tissue temperature stability criteria is assessed during the Temperature Stabilization Phase.



temp perf thing CALIGRAPH


When the system determines that the temperature stabilization criteria has been met, the BPM advances to the tissue Calibration Phase automatically. In this 10 second period, the K and PPA values are calculated.

Next is the Perfusion Measurement Phase:


The first two minutes after calibration are referred to as Blackout.

During Blackout, the thermal field is at the early stages of development and therefore no data is presented.

The next two minutes are referred to as Grayout.

The thermal field is more developed and the BPM presents a blinking perfusion value.

When the perfusion value stops blinking, the thermal field is sufficiently developed and the data will start to plot on the screen.

The BPM will then monitor perfusion for the selected period of time (default 30 minutes).





  • Set up and turn on BPM
  • Connect umbilical cord to BPM
  • Place and fix probe in region of interest
  • Connect probe to umbilical cord
  • Allow temperature stabilization and calibration phases to give tissue assessment
  • Use PPA and K values to evaluate probe placement
  • Monitor your patient
