Area of Science:

  • Biomedical Engineering
  • Physiological Measurement

Background:

  • Photoplethysmography (PPG) non-invasively detects tissue blood volume changes.
  • The PPG signal has pulsatile (AC) and baseline (DC) components.
  • The AC component reflects heartbeat-induced blood volume variations.

Purpose of the Study:

  • Investigate the AC pulsatile waveform of PPG.
  • Extract biomechanical properties of tissue and vasculature.
  • Assess PPG for diagnosing vascular complications.

Main Methods:

  • Analyzed PPG pulse rise time during diastole.
  • Used tissue-mimicking phantoms to measure Young's Modulus.
  • Employed a Windkessel model to simulate circulatory biomechanics.

Main Results:

  • PPG measured Young's Modulus changes with 4 KPa resolution (12-61 KPa range).
  • Pulse shape differentiation may aid in diagnosing upstream vs. downstream vascular issues.
  • Modeling confirmed in vitro findings and PPG waveform trends with altered compliance and resistance.

Conclusions:

  • PPG's AC component is valuable for assessing tissue and vascular biomechanical properties.
  • PPG shows potential for non-invasive diagnosis of vascular conditions.
  • Further research can leverage PPG for advanced physiological monitoring.
