The higher value determines the evaluation.
Example: If no shock, a blood pressure of 150/85 or 120/98 will
show as «blood pressure high».
4. Data Memory
This instrument automatically stores the last measured blood
pressure values.
Viewing the stored value
Hold down the ON/OFF button (the instrument must have been
switched off beforehand) until memory appears and then release
the button.
5. Battery Indicator and Battery charging
Low battery
- When the battery is almost empty the battery
symbol
AN
will flash as soon as the instrument is switched on
(partly filled battery displayed). The instrument will continue to
measure reliably, you should charge the battery after flat battery
symbol appear.
Flat battery – charge the battery
When the battery is flat, the battery symbol
AN
will flash as
soon as the instrument is switched on (flat battery displayed).
You cannot take any further measurements and must charge the
battery.
1. Connect the instrument to the 5 V USB power adapter or
computer using the USB cable.
The connected power adapter and computer need to
meet IEC60950-1 or IEC60601-1 standard.
The USB connection can't be used to transfer any data
between PC and device. It is used for charging the
battery only.
2. During the charging process, the charging indicator
AT
will light
up in orange.
3. When the battery is completely charged, the charging indicator
will light up in green.
5. During the measurement, the pulse indicator
AQ
flashes on
the display and a beep sounds every time a heartbeat is
detected.
6. The result, comprising the systolic
AK
, the diastolic
AL
blood
pressure value and the pulse rate
AM
is displayed and a
longer beep sound is heard. Also look at the explanations in
this booklet.
7. When the measurement is completed, remove the cuff from
the patient's arm.
8. Switch off the instrument. (The monitor does switch off
automatically after approx. 30 sec.).
3. Hypertension and Shock Indicator
Shock, due to bleeding or sepsis, can cause a change in blood
pressure and heart rate. Shock index is defined as heart rate
divided by systolic blood pressure.
When measurement is completed, the symbol
AO
and traffic light
9
may indicate that your blood pressure or shock index is higher
than the recommended range.
