4.4 General Information on Ambulatory BP
Measurement
It is recommended to operate the device in the mode
„activated inflation measurement“. This mode
significantly shortens the measurement time of an
individual measurement and therefore offers greatly
increased comfort with significantly reduced stress for
the patient.
A manual measurement can be taken at any time between
the automatic measurements. Manual measurements are
marked with “+” in the measurement value table.
If unsuccessful, the device will repeat a measurement
after 2 minutes. An error code referring to failed
measurements is generated in PhysioPortWin only after
three consecutive unsuccessful measurements.
Error codes “E04” (battery depleted), “E07” (inflation
time over) and “E10” (400 blood pressure measurements
taken) do not lead to a second measurement. The next
measurement after error code “E07” occurs at the
selected interval.
After error codes “E04” and “E10”, the device enters the
power-save mode to prevent over-discharging of the re-
chargeable batteries. This mode can only be terminated
by turning the device off and on again.
Deflation Measurement Method:
If “activated inflation measurement” is not activated by
putting a checkmark, the PHYSIO-PORT device operates
in the conventional „deflation measurement method”. For
the first measurement, the cuff is inflated to a pressure of
160 mmHg (initial pressure). For subsequent measure-
ments, the device inflates the cuff to a pressure which is
25 mmHg above the systolic value of the previous
measurement (minimum inflation pressure: 120 mmHg).
The determination of the blood pressure values takes
place when the cuff pressure is gradually decreased.
If the measured value is above the inflation pressure, the
device will increase the cuff pressure another 50 mmHg.
Inflation Measurement Method:
For each measurement, the device inflates the cuff about
20 mmHg above the determined systole and then
immediately vents the cuff completely.
Pulse Wave Analysis
With the PHYSIO-PORT AS it is possible to combine
the pulse wave analysis with both blood pressure
measurement methods. The holding pressure after the
blood pressure measurement is equal to the measured
mean arterial pressure level (MAD).
4.5 Toggling Between Day and Night Phase
In the three measurement protocols, the day phase lasts
from 7 a.m. to 10 p.m. and the night phase from 10 p.m.
to 7 a.m. On the display, the two phases are represented
by the symbols (day) or (night).
Patients whose day and night phases are different from
these predefined periods can push the button twice
to change from one phase to the other.
4.6 Audio Signal
If enabled, the audio signal will be emitted in the
following situations:
shortly after the PHYSIO-PORT device has been
switched on
just before the PHYSIO-PORT device starts
inflating the cuff (during the day phase only)
after the PHYSIO-PORT device has detected an
erroneous measurement
Note
If the measurement protocol was created with
PhysioPortWin and only one BP period has
been specified, switching from one phase to
the other will leave the measurement intervals
unchanged. They will always be the same.
The information "day phase" and "night
phase" is only used to identify the measure-
ments.
