RRp Settings
When using a pulse oximetry or pulse CO-Oximetry sensor with Radius-7, respiration rate can
be determined by the plethysmographic waveform (RRp). This method measures a patient's
respiratory rate based on plethysmographic amplitude changes that correspond to the
respiratory cycle. When using a pulse oximetry or pulse CO-Oximetry sensor, RRp alarms and
RRp settings are active and the parameter label displays as RRp.
Note that the Radius-7 can monitor RRa or RRp but not both simultaneously. RRp is active
under the following conditions:
• RRp is installed on the Radius-7.
• Pulse oximetry or pulse CO-Oximetry sensor is connected.
• Acoustic sensor is not connected.
