Operation Manual
The patient should then be comfortably seated or allowed to lie down in the study room and
relax for at least 15 minutes or a sufficient period to reach a relaxed cardiovascular steady-
state and to adjust to the room temperature.
6.1.4
Patient blood pressure measurement
The blood pressure measurement procedure may affect the vascular conditions of the patient.
Therefore, if blood pressure measurement needs to be taken prior to the EndoPAT
TM
study,
the following should be considered:
The blood pressure should be measured from the patient’s control arm (the arm that
is not occluded during the EndoPAT
TM
study).
It is recommended to allow 30 minutes between the time of the blood pressure
measurement and commencement of the EndoPAT
TM
test.
6.1.5
Positioning the patient
The patient should sit in a reclining chair or lie down comfortably. In either case the patients’
hands must be supported at approximately heart level.
6.1.6
Preparation of fingers and hands before a study
The finger should be inspected for any deformities or injuries that could affect the study. The
probe should not be used on a finger that is cut, injured or unusually sensitive. Fingernails
should be trimmed and filed if necessary to avoid damaging the internal membranes of the
PAT™ probes & displacing the finger from the sensing region of the probe, resulting in a
smaller PAT™ signal and inaccurate results. The index finger is the recommended finger for
the study, however if this finger is too large to comfortably fit into the probe or is otherwise
unsuitable (see above), a different finger (except the thumb) may be used, as long as it is the
same finger in both hands.
WARNING
Long nails may cause distorted PAT™ signals and may cause the
study to fail.
Before inserting the fingers into the probes, ensure all heavy clothes, tight fitting sleeves,
rings, watches, and jewelry were removed from patient’s hands and arms.
