upright at all mes during a test.
To start a breath test,
touch the or
icon. The unit will beep
once.
The or icon will

,
ensuring that the ball in the ow
indicator is held in the middle of the
band on the NObreathFlo

The exhalaon me is approximately
12 seconds for an adult and 10
seconds for a child; a progress bar is
shown at the boom of the screen.
Paents should connue to exhale
unl the progress bar has reached
its limit. A double beep will sound

Aer a paent test has been
completed, remove the

from the NObreath®.
Remove and dispose of the
mouthpiece safely. This should be
done in accordance with local waste
disposal guidance.
The icon shall appear at the

the reading is displayed. This allows
me for the sensor to sele to zero

Quick start guide
• Ensure that the NObreathFlo
TM
and mouthpiece are
ed correctly to the front of the monitor.
• The NObreath® device should be held upright, this helps
the paent to maintain the correct ow rate by keeping
the ball elevated in the centre of the marked area on
the NObreathFlo
TM
.
• Two measurements, within 10% dierence of each
other, must be achieved before making a nal result.
• Paents should wait 3-5 minutes between tests in order
to allow NO levels to stabilise.
• Paents should not hold their breath before exhalaon,
they should take a deep breath in and then a long slow
exhalaon at 50ml/s as indicated on the NObreathFlo
TM
.
