Application
2001589-085 Revision G TONOPORT V 19
Initiate a Trial Measurement
Turn on TONOPORT V and place it in the carrying
pouch. There is an aperture in the pouch to accommo-
date the cuff connection tube.
Attach the pouch to the patient (shoulder strap, belt).
For reasons of hygiene, it is not advised to carry the
pouch on the bare skin.
Guide the pressure tubing around the patient's neck as
a strain relief and connect it to the blood pressure cuff
port on the TONOPORT V (1, Fig. 2-1). Advise the
patient to avoid kinking the tubing during the mea-
surement.
Check that the display indicates the time of day. If the
memory contains data from a previous procedure, the
letter "M" will appear on the display when you turn on
the device. If you still try to initiate a measurement,
the message "LLLL" prompts you to clear the memo-
ry. Push twice to delete the data. If you do not
wish to delete the data, turn off the device instead of
pushing .
To avoid erroneous measurements, ensure that the
patient does not move during the trial measure-
ment. The patient may stand or sit.
Push to initiate the first measurement.
Within a few seconds, the device starts inflating the cuff.
When the inflation pressure has been reached, the cuff
will gradually be deflated. The changing cuff pressure is
indicated on the display and the letter "M" appears with
each detected oscillation. At the end of the measurement
the measured data appears in the following order
– the systolic reading (S in mmHg or kPa)
– the diastolic reading (D in mmHg or kPa)
– the pulse rate (HR/min
-1
).
If an error code, such as "E 29" (insufficient number of
oscillations detected) is displayed after the measurement,
tighten the cuff a little and push again (see also
chapter 6 "Error Codes").
If the trial measurement has been successfully completed,
the device is ready for automatic measurements.
Patient Information
Advise your patient
– not to move while a measurement is being taken to
avoid motion artifacts that may lead to erroneous
readings and to keep the cuff inflation time as
short as possible
– to place TONOPORT V on the night stand while in
bed
– how to switch the device manually from the day to the
night phase (see page 21)
– that events considered important should be noted
down in a diary and that intermediate measurements
can be initiated with
– that the measurement can be stopped at any time with
(the cuff will be deflated)
– not to open the battery compartment
– about the audio signal and its meaning.
Warning
Risk to persons —
Instruct your patient
– to terminate the measurement with ,
whenever the cuff is not deflated within about
2minutes,
– to remove the cuff if it is not deflated after
activation of the button. This could be due
to kinked tubing. The cuff must be reapplied as
described earlier before additional
measurements can be taken.
