There is a close relationship between emotional tensions and respiratory function, which makes it likely that many diseases of this apparatus have aetiology or are compromised by psychogenic factors, which occurs, for example, in allergic diseases such as rhinitis and asthma, as well as in certain inflammatory diseases. Asthma is diagnosed by the sensation of oppression in the chest, dyspnea that can evolve to cyanosis, discrepancy between the combined action of the diaphragm and the levator muscles of the ribs, which remove air through the narrowed bronchioles, and the weak exhalation force, which depends on the elasticity of the lungs, making breathing difficult and leading to emphysema during paroxysm. In the initial stages there may be simple cough; later, the expectoration of a thick, foamy phlegm begins. The temperature is normal and the pulse is tachycardic. Auscultation reveals crackling rales and wheezing. Asthmatics can improve with the various types of psychotherapy: supportive, cognitive behavioral techniques, counseling, relaxation techniques and mainly psychoanalytic therapy, either individual or in group. In conclusion, the treatment of asthma and allergic rhinitis, should be done by two specialists, the allergist and the psychotherapist.
