Measuring Vital Signs ​

  • Position your face in the center of the camera preview.
  • Click the Start button.
  • Pulse Rate vital sign values (this is an example of an "instantaneous" value) should be received after approximately 11 seconds.
  • After the measurement ends (either by tapping on the Stop button or at the end of the defined measurement duration), Pulse Rate (PR), Respiration Rate (RR), Stress Level (SL), SDNN and Blood Pressure (BP) results will be shown (this is an example of a "final" result).
  • The final results may be invalid if there was insufficient measuring time.
