4 Connect the ClearSight Finger Cuff to the Pressure
Controller.
 Do not rotate the cuff after application. The hook located
on the outside of the finger cuff should be situated on the
back of the finger at all times.
5 If continuous monitoring is expected to last longer than 8
hours, or to increase patient comfort, repeat cuff sizing
and steps 1-4 to apply an additional cuff to a second finger
on the same hand.
Single Patient Use The ClearSight Finger Cuff is
designed for single patient use. Upon starting a measurement,
the Finger Cuff will expire after 72 hours for a single patient.
Double Cuff Application. The EV1000 NI allows two
ClearSight Finger Cuffs to be connected simultaneously to
alternate the measurement between two fingers. This feature
allows for continuous monitoring for durations of up to 72
hours and is required for measurements that take longer than
8 hours. This feature can also be used to increase patient
comfort. Accumulated monitoring on one finger is limited to
8 hours.
