Respiration Rate

Acoustic Respiration Rate (RRa) provides noninvasive and continuous monitoring of respiration rate

Rainbow Acoustic Sensor

  • >  Adhesive Respiratory Acoustic Sensor (RAS) is applied to the neck, near the trachea, detecting the vibrations associated with respiration 
  • > Using acoustic signal processing that leverages Masimo Signal Extraction Technology® (SET®), the respiratory signal is separated and processed to display continuous respiration rate
