Area of Science:

  • Cardiovascular Physiology
  • Biomedical Engineering

Context:

  • Growing demand for noninvasive cardiovascular assessment techniques.
  • Advancements in technology driving availability and interest in these methods.

Purpose:

  • To present photoplethysmography (PPG) and impedance cardiography (ICG).
  • To explain their principles, capabilities, and limitations for hemodynamic assessment.

Summary:

  • PPG and ICG offer new avenues for hemodynamic evaluation in conditions like shock, pulmonary edema, heart failure, hypertension, and eclampsia.
  • These techniques can optimize pharmacotherapy and stimulation in cardiac patients.
  • They aid in understanding the relationship between autonomic nervous system activity and hemodynamic changes.

Impact:
