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


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.
