Usually when patients have inflammatory infections, there will be out of breath are feverish, for example, in the bacterial infection and lead to an increase in body temperature, then out of breath will feel the clinical symptoms and manifestations of fever, because the body is infected with bacteria, viruses and other pathogenic microorganisms, at this time, there is the body’s antigen-antibody reaction, there will be an endogenous pyrogenic source of heat, the above mentioned factors will be released, such as tumor necrosis factor, interleukins These factors release substances such as tumor necrosis factor, bradykinin, leukotrienes, etc., which can lead to an upward shift in the neuronal tuning point of the body temperature center. As a result, there is a response of elevated body temperature on both outbreathing and panting. The reflexive increase in body temperature is a physiologic response and a pathologic reflex of the body to expel pathogenic microorganisms from the body, which results in clinical symptoms and manifestations of self-consciousness of warmth both on wheezing and on exhalation.
