SA Series Ambulatory Blood Pressure Monitor User Manual Conducting an Ambulatory BP Study
- 22 -
WARNING
Prolonged non-invasive blood pressure measurements in Auto mode may be associated
with purpura, ischemia and neuropathy in the limb wearing the cuff. When monitoring a
patient, examine the extremities of the limb frequently for normal color, warmth and
sensitivity. If any abnormality is observed, stop the blood pressure measurements.
5.3 Preparing the Patient
To ensure measurement readings are valid, provide your patient with the following instructions.
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. It is better to lie flat when asleep.
It is expected that the patient may experience some mild to moderate discomfort during a
blood pressure measurement. Instruct the patient to turn off the device, remove the cuff, and
notify the doctor if they are experiencing pain, swelling, redness or numbness in the limb
where the cuff is placed.
Wear a loose and comfortable shirt for the ABP study. Do not go swimming or bathing.
Do not operate heavy machinery or power tools. Vibration may compromise the performance
of monitor.
Avoid car driving or bus taking. Try to keep the monitor dry and do not drop it.
Do not use the monitor if accidental wetting, drop or damage occurs to it or its parts. Please
power off and return it to EDAN.
Before sleeping, the patient should make sure that the hose is not and will not become
kinked.
The patient can stop a measurement in progress by pressing the Start/Stop button.
The batteries can be replaced during a study without the data being lost or interrupting the
monitor’s program. Alternatively, the monitor can be turn off without losing its data. The
study will go on as programmed.
If cuff fails to deflate within two and a half minutes, instruct the patient on manual removal
of cuff.
5.4 Measurement Limitations
Measurements are impossible with pulse rate extremes of less than 40 bpm or greater than 240
bpm, or if the patient is on a heart-lung machine.
The measurement may be inaccurate or impossible in the following situations:
A regular arterial pressure pulse is hard to detect.
Patients with cardiac arrhythmias.
