Performing arterial occlusion
After a stable period of the required baseline signal recording (5-6min.), prepare for the
occlusion:
1.
Select Max Gain button
of the occluded arm (either probe A or probe B)..
2.
Inform the patient you are about to inflate the blood pressure cuff, stressing the
importance of remaining still during the test.
3.
Rapidly
inflate the blood pressure cuff to a supra-systolic level (the recommended
pressure is at least 60mmHg above systolic blood pressure and no less than 200mmHg).
Verify total cessation of blood flow to the hand ( as reflected by a total absence of PAT™
signal from the occluded hand). If the appearance of any PAT™ signal is noted, increase
cuff pressure by an additional 50 mmHg and up to 300mmHg (See Figure 43).
Warning
Inflating the BP cuff might cause some stress and discomfort to the
patient. Pay attention to the patient’s well-being.
4.
Maintain the arterial occlusion for exactly five minutes – periodically check the pressure
in the occluding cuff is maintained; increase pressure if required.
NOTE
Once the occlusion has been performed the test should not be re-started.
It is recommended to wait at least 2 hours prior to performing a new
study.
