Preparing and educating the patient
When conducting blood pressure measurements, including hypertension blood
pressure measurements, with an oscillometric NIBP device, it is important to follow
suitable procedures to ensure valid, accurate results. Preparing your patient for
the ABP study is the most important step to achieving a successful test. Review the
following instructions with your patient.
• When the pressure in the cuff increases, the patient should avoid excess movement
during measurements. Let the cuffed arm hang loosely, slightly away from the body with
the middle of the cuff at heart level. Avoid flexing the muscles or moving the hand and
fingers of the cuffed arm.
• The patient can stop a measurement in progress by pressing the Start/Stop button.
• If the keypad is enabled when programmed, the patient can start a measurement at any
time by pressing the Start/Stop button.
• Between BP readings the cuff should not be removed.
• While sleeping, the patient should make sure that the hose is not kinked.
• The batteries can be replaced during a study without the data being lost or interrupting
the monitor’s program. Alternatively, the monitor can be turned off without losing its
data.
• Instruct the patient on how and when to fill out the patient diary.
• Ensure the patient knows how to care for the monitor. Keep the monitor dry and do not
drop it.
• If the monitor or cuff causes extreme pain or pain not normally associated with blood
pressure measurement, the patient should remove the cuff and turn off the monitor.
• The patient should not talk during the BP measurements.
• The patient should be seated, standing or lying down. If the patient is seated, they should
have their legs uncrossed, feet flat on the floor with their back and arms supported.
Starting the study
Before the patient leaves with the monitor and cuff correctly instrumented, verify that
the monitor operates correctly.
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 5 seconds. The
Opti
will beep
5 times and the display will turn off. When the patient returns, take the cuff, monitor,
and belt off.
Notes on blood pressure data
Any blood pressure reading can be affected by the measurement site, the position
of the patient, exercise, or the patient’s physiologic condition. Environmental or
operational factors which can affect the performance of the device and/or its blood
pressure reading are common arrhythmias such as atrial or ventricular premature
beats or atrial fibrillation, arterial sclerosis, poor perfusion, diabetes, age, pregnancy,
pre-eclampsia, renal diseases, patient motion, trembling, and shivering.
Before retrieving data from the monitor, ensure that the monitor is disconnected from
the patient before connecting the ABP monitor to any piece of hardware such as your
personal computer.
To retrieve the data:
1. Click on the Retrieve
toolbar button, or pull
down the Monitor menu
and select Retrieve Data.
2. Communication starts
automatically. The dialog
box on the screen shows
the progress as the
data is transferred.
3. After completion, a dialog
box asks if this is a new
patient. If you click No, a
list of current patient files
will appear (Fig. 8). Select
the patient file to save the
retrieved data.
4. If you click Yes, the Patient
information dialog box
(Fig. 9) will appear. Enter
patient information in the
data fields.
5. Click the OK button to
save the data.
The patient’s BP data is now
saved as a file on your computer. The
ABP Data
tab displays the retrieved data.
The patient’s name, ID#, test date, file name and its location are displayed in the
status line located at the bottom of the display area.
NOTE
: If you do not retrieve data from the monitor, this data will be lost
when you program it for the next study.
