The relatively heavy breath sounds are commonly associated with some diseases of the respiratory system, such as adenoid hypertrophy, deviated nasal septum, congenital nasal malformations, chronic rhinitis, sinusitis, etc. They are also seen in bronchitis. In this case, blood tests, cranial CT, nasopharyngoscopy, and X-ray or CT of both lungs can be taken to clarify the above possible diagnosis. For nasal polyps, deviated nasal septum and congenital nasal malformations, surgical treatment can be performed. For bronchitis, caused by viruses, interferon nebulization can be chosen. Anti-viral oral solution, ribavirin, oseltamivir, and cytarabine can be used appropriately. In addition, for bacterial infection, antibiotics such as amoxicillin, cefoperazone, clindamycin, levofloxacin and other drugs can be chosen.
