Dear Customer,
Thank you for choosing Accutension. Before you use the product,
please read the manual carefully and follow the instructions. This
kit is not an automatic blood pressure monitor, so some practice
may be needed to make it work properly. Please contact us if you
encounter any problem.

Setup the kit
Figure 1 shows how the parts are connected together and how
the kit is operated. The cuff tube is connected to the pressure
sensor module, then to the slow deflation vent and then to the
hand pump with quick release valve. You can use the short rubber
tube we provided to make the connection. Three slow deflation
vents with different deflation rates are provided.
provided You need to
choose the right one after you learned your rough blood pressure
value and the right cuff size with the aid of App that will be
introduced later. You need to choose the right cuff size. The cuff
has an index and please make sure it is within the OK range when
you wear it.

and deflation. No. 5 and 6 are the systolic and diastolic BP marking
lines respectively. You can move No. 5 to the first sound of blood
flow pulse and No. 6 to the last. These two lines can be moved by
scrolling No. 8. When you scrolling up and down No.8, the numbers

INDEX needs to be within the OK range as printed in the cuff,

Start measurement. Quickly pump the cuff to the pressure
30mmHg higher than the estimated blood pressure value. For
example, if your systolic blood pressure is 120mmHg, you need
to pump the cuff to at least 150mmHg. Then stop pumping, the
cuff will start self deflation. You can see the sound signals on the
phone screen. The Korotkoff sound signal will appear when the
systolic blood pressure is reached. Then the sound signal will
continue on the screen until the diastolic blood pressure is
reached. Then yyou need to p

quick release button on the
manual pump to quickly deflate the cuff. Please make sure the
cuff air is fully released when you release the button. Now the
phone should display the blood pressure value. Please be noted
that the blood pressure value is not the final value because this is
not an automatic blood pressure kit. You might need to playback
the sounds to double confirm.
confirm
Choose the right slow deflation vent. There are three slow
deflation vents in grey, white and blue respectively. The grey one
has the fastest deflation while the blue one has the slowest
deflation. The deflation speed will be showed after each
measurement. The best deflation speed is 2 ‐ 4mmHg/s, so if it is
higher than that,
that please select a slower deflation valve.
valve The ideal
range of deflation speed is 2mmHg‐4mmHg to balance accuracy
and comfort.
Playback the sounds. Touch Playback in the App to playback the
sounds. You need to use headphone to listen clearly because the
iphone speaker is not good at playing low frequency (bass)
sounds.
Adjust the reading if necessary. You can scroll the blood
pressure number picker to adjust the blood pressure marking
line location.
Interpret the sounds curve. Figure 3 shows various sounds
strength curves. Please note noise such as friction can induce a
peak in the sounds curve, so the features of blood flow sounds
can help you recognize the noise sometimes.
(a) is the most common curve. It shows regular heart beat, there
is clear first sound and last sound of blood flow pulse. ① is
systolic BP and ② is diastolic BP.
((b)) shows there is a gap
g p between regular
sounds signals.
For this
case, you need to listen to confirm whether the first part ① ‐ ②
are the blood flow pulse sounds or noise. If they are the former,
the gap is called auscultatory gap and it happens to some people.

Accutension can help you find out this kind of irregular heart beat.
You need to consult your doctor when you find this phenomenon. It
could be linked to some diseases.
Turn off the pressure sensor module. Please do not forget to turn
off the pressure sensor module after use!

Others:

The sound quality determines the measurement quality. So
g.
please do your best to avoid noise. For example, find a quiet
place to do the measurement. Ask others not to talk during
measurement. Keep the tube of the stethoscope clear from
the cuff tube to avoid unnecessary noise. Don’t touch the
tube of the stethoscope during measurement.
Please do not use when you charge your phone because of
heavy electrical noise.
If you have questions on the sounds or the number, you can
send the sounds to your doctor or medical professionals
through
g email. You doctor can open
p the measurement data
in his/her phone to find the BP readings for you.
Follow all the normal blood pressure measurement
requirement. For example, take a rest before measurement,
be seated on a chair with back support, put two feet on the
floor, keep the cuff on the same level of the heart, etc.
The pressure sensor module can be cross‐calibrated with
most of the upper arm automatic blood pressure monitors
or traditional blood pressure kit, so if you find any abnormal
of the pressure number, you can do this by finding another
blood pressure monitor.
You can use the micro USB cable to charge the pressure
sensor module.

You can use Accutension Stetho App to check the algorithm
accuracy of an automatic BPM. That App requires a QR code
to register. Here is the code to scan. In the future,
Accutension App may also need this code. So Please keep
this manual.
