Description
Diaphragmatic Breathing (DB) involves a slow, deep inhalation through the nose using the diaphragm while lying on your back, with one hand resting on your chest and the other on your abdomen. It is essential to keep movement of the chest to a minimum and concentrate on the stomach pushing against the hand, involving the diaphragm. Typically, practitioners breathe in and out for around six seconds each.
Innovation
This technique is the basis of breathing exercises and should be combined with other techniques. However, when used individually, it can reduce the work of breathing.
Evaluation System
To assess whether this technique has been effective, the following aspects should be evaluated: Respiratory rate, respiratory amplitude, respiratory rhythm, the ability to dissociate and control respiratory times and peripheral O2.
Assessment
RD can be beneficial for reducing physiological and psychological stress and can improve respiratory function and the strength of the respiratory muscles; conscious use of the diaphragm during breathing increases lung capacity; RD increases blood pressure and heart rate variations by encouraging slow breathing and movement of the diaphragm. Consequently, it increases baroreflex sensitivity, heart rate variability and blood pressure fluctuations.
