signal. See rainbow Acoustic Monitoring™ (RAM™) on page 25 of the Operator's Manual. When
the respiratory rate is determined by the acoustic signal, RRa alarms and RRa settings are
active, and the parameter label displays as RRa.
RRa is active under the following conditions:
• RRa is installed on Radius-7.
