the Radical-7 Pulse CO-Oximeter .

3D Alarm System Overview

The Radical-7 Pulse CO-Oximeter includes user-selectable High and Low alarm limits for

SpO

and pulse rate to provide audible and visual indication of specific levels of these vital

signs that the clinician has determined merits their attention as described in Section 4 of

interacting factors to provide an additional level of vigilance and flexibility to manage their

patients.

The following is a summary of each of the 3D Alarm System features:

DESAT INDEX ALARM

The Desat Index Alarm is a user-selectable feature which allows a clinician to request an

audible and visual alarm if a patient experiences a specified number of desaturations over

a specific period of time.

PERFUSION INDEX (PI) DELTA ALARM

The PI Delta Alarm is a user-selectable feature which allows a clinician to request an

audible and visual alarm if perfusion at the monitored site decreases by a specified level

(delta) over a specific period of time.
