Overview of RRp
Respiration rate can be determined by the plethysmographic waveform (RRp) using a SpO2
sensor. Respiration rate monitoring, derived from the plethysmographic waveform,
measures a patient's respiratory rate based on amplitude changes that correspond to the
respiratory cycle.
Inaccurate measurements may be caused by:
Low arterial perfusion
Motion artifact
Low arterial oxygen saturation
Excessive ambient or environmental noise
Improper sensor placement
The device can display respiration rate derived from the plethysmographic waveform under
the following conditions:
Respiration rate parameter installed on the instrument
Active optical channel
Dual Rainbow cable is disconnected
RRp Alarms
From the Alarms screen, change any of the following options:
