The patient should not talk during BP measurements. The patient should be seated, standing
or lying down. If seated, the patient should have legs uncrossed, feet flat on the floor with back
and arms supported.
Starting the Study
Before the patient leaves with the monitor and cuff, verify that the monitor operates correctly. To verify
proper monitor operation, ensure that the monitor is on and start a BP reading by pressing the Start/Stop
button. The cuff will inflate and complete the brachial BP measurement. If CBP measurement has been
programmed, before the cuff is fully deflated, the monitor will hold pressure in the cuff for ten seconds to
capture the waveform data required to derive CBP values. The cuff will then be fully deflated. The clock icon
should appear on the display of the Oscar 2 indicating that the study is in progress. If problems occur, review
the setup and fitting of the system.
Replace the batteries (2 AA alkaline batteries) for every study with new batteries. Failure to do so may result
in incomplete 24-hour studies.
To record an event:
Press the Event button
The monitor sounds a long audible beep for confirmation, and "rcd : 01" appears on the display (Subsequent
recordings use 02, 03, and so on). The monitor can record up to 30 events. If the patient tries to record more
than 30 events, the monitor beeps four times, and "No rcd" appears on the display.
Note: If Event Marking is enabled, then the Dosage Response feature will be disabled.
To start a dose response sequence:
Press the Event button.
The monitor sounds an audible beep for confirmation and begins the first reading in the sequence. The Event
button is disabled until all readings in the sequence are complete.
Note: If Dosage Response is enabled, then the Event Marking feature will be disabled.
To manually set day (Awake) or night (Asleep) mode:
Press the Day/Night button.
The monitor beeps and displays either the sun or moon icon depending on the mode that it was switched to.
If switching to Night mode, the monitor will display a moon icon.
If switching to Day mode, the monitor will display a sun icon.
Finishing the Study
If you wish to finish the study before the patient returns, instruct the patient to turn off the monitor by holding
down the Start/Stop button for five (5) seconds. The Oscar 2 will beep five (5) times and the display will turn
off.
When the patient returns, take the cuff, monitor, and belt off and download the captured data to AccuWin Pro
4 for review.
