General Information on Ambulatory BP
Measurement
These are the buttons on TONOPORT VI used during an
ambulatory blood pressure measurement:

Deflation measurement method:
For the first measurement, the cuff is inflated to a
pressure of 160 mmHg (initial pressure). For subsequent
measurements, the device inflates the cuff to a pressure
which is 15 mmHg above the systolic value of the
previous measurement (minimum inflation pressure:
120 mmHg).
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 to a
pressure just above the expected systolic pressure.
A manual measurement can be taken at any time between
the automatic measurements. Manual measurements are
marked in the tabular BP data in CardioSoft.
If unsuccessful, the device will repeat a measurement
after 2 minutes. An error code referring to failed
measurements is generated in CardioSoft only after three
consecutive unsuccessful measurements.
Error codes E02 (battery depleted), E06 (inflation time
over) and E08 (maximum number of pressure
measurements taken – 200 or 400) do not lead to a second
measurement. The next measurement after error code
E06 occurs at the selected interval.
After error codes E02 and E08, the device enters the
power-save mode to prevent over-discharging of the
rechargeable batteries. This mode can only be terminated
by turning the device off and on again.

Application
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
Patients whose day and night phases are different from
these predefined periods can push the
to change from one phase to the other.
If the measurement protocol was created with
CASE/CardioSoft and only 1 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 measurements.
Audio Signal
If enabled (see page 18), the audio signal will be emitted
in the following situations:
– shortly after TONOPORT VI was switched on
– just before TONOPORT VI starts inflating the cuff
(during the day phase only)
– after TONOPORT VI has detected an erroneous
measurement
TONOPORT VI
(day) and (night).
