Capnography
The Capnotrainer is a non-invasive biofeedback assessment device that provides us with information about breathing physiology by showing the partial pressure of carbon dioxide in exhaled air.
A common feature of breathing pattern disorders is chronic hyperventilation causing a drop in CO2, raised PH leading to smooth muscle contraction and decreased oxygenation.
Capnography shows us the shape of the breathing ‘wave’, the breathing rate and level of exhaled CO2.
A mechanics training mode can then help patients to understand and experience the correct rate of breathing as well as experience the sensations associated with restoring normal CO2 levels.
The mismatch of subjective experience and ‘normal’ is often a reason for perpetuating over breathing.
