A Versatile and Convenient Solution for Obtaining Respiration Rate

Available alongside clinically proven Masimo SET® pulse oximetry, RRp allows clinicians to seamlessly implement respiration rate monitoring without additional equipment. RRp provides visibility to an additional key vital sign in a comprehensive single-sensor solution that is well tolerated by patients.

  • Increased visibility of respiration status: By automating respiration rate monitoring, RRp trend data provides increased visibility to changes in respiration compared to periodic manual counting.
  • Single-sensor solution: The addition of RRp to SpO2 monitoring streamlines access to both oxygenation and respiration status without additional cables or sensors.
  • Available for multiple populations: RRp provides respiration rate continuously and noninvasively for both adult and pediatric patients.

Changes in the Plethysmographic Waveform During Breathing

Changes in the Plethysmographic Waveform During Breathing


RRp is a measure of respiration rate based on changes in the plethysmographic waveform.

Masimo - Advanced signal processing

Advanced signal processing is used to analyze baseline, amplitude, and frequency changes to the plethysmographic waveform over the respiratory cycle to calculate respiration rate.
