Quick start guide

• Ensure that the NObreathFloTM 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 NObreathFloTM.
• 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 NObreathFloTM.
