PHYSIOLOGICAL BACKGROUND
The physiological background of the
pulmonary parameters.
The lungs are made up of airways,
bronchi, bronchiole and millions of
alveoli. The diameter of the smallest
bronchiole is very small compared to
the large bronchi and the airways.
The one second capacity (FEV1)
measures in the first second the ma-
ximum exhaled lung volume. This
measurement predominantly mirrors
a narrowing of the large airways. The
six second capacity in contrast is
the standard for the measurement of
changes to the small airways.
Unlike to the bronchi, the bronchio-
le are not stabilized by cartilage, but
rather, held open by elastic draws in
the lung tissue. When inhaling deeply
these draws cause the bronchiole to
expand. When exhaling the draw of
the lung tissue lets up due to the shrin-
king lung volume which narrows the
bronchiole even more.
The Six Second Capacity (FEV6)
measures the “rest” breathing volume
after 6 seconds of exhaling. That is, at
a point in time at which the retraction
power of the lung volume, as descri-
bed above, is significantly diminished.
COPD is an illness which besides the
larger airways (mucous buildup, nar-
rowing) primarily effects the smallest
airways and the pulmonary alveoli.
This results in dissolution of the setting
of the smallest airways and thereby
causing a diminished holding open of
these bronchial parts during exhaling.
The FEV6 mirrors therefore the distur-
bances in the pulmonary periphery si-
gnificantly better than the FEV1. From
the ratio FEV1/FEV6 the narrowing of
the smallest airways can be determi-
ned.
With illnesses such as pulmonary fi-
brosis (an airway restricting illness)
the fibrosis affected lung tissue of the
bronchiole is pulled apart, so that with
a generally diminished FEV1 (due to
diminished lung volume with pulmona-
ry fibrosis) the FEV6 is in comparison
significantly increased.
With COPD we observe disturbances,
which can be (partially) rectified with
medicine and other changes which are
caused by physical disturbances of the
lung tissue and thereby cannot respond
to medicine.
Here the physical therapy, for example
with the RC-Cornet (basic cornet), can
help. This respiratory therapy device
loosens mucous, stabilizes and expands
the small bronchi and reduces shortness
of breath of the patient.
