Spirometry/ Lung function
Testing
When you attend your outpatient appointment you
may be asked to carry out a lung function test. Lung
function tests measure how well your lungs are
working.
.
You will be taken to
the lung function room
which has all the
special lung function
testing equipment in.
The cubicle that you
will be asked to sit in
looks a bit like a
shower cubicle.
The respiratory
technician will then
explain how the test is
carried out and give
you the chance to have
a practice at blowing
through the filter.

After your practice
blow you will be
asked to sit in the
cubicle and carry out
the test.
 You will be asked to
blow out as fast and as
long as you can

There are some
incentive games to
play while the test is
being carried out.
 The test will not take
long and we aim to
make them as fun as
possible.
