If tracheitis is suspected, a physical examination can be carried out, including auscultation and percussion of the lungs. Additionally, blood tests should be conducted for routine blood work, mycoplasma, chlamydia, C-reactive protein, as well as auxiliary examinations such as chest X-rays or CT scans to confirm the presence of tracheitis. For symptoms caused by this condition, mild cases can be relieved with oral antibiotics, antipyretics and analgesics, and medications that thin mucus; severe cases may require oxygen therapy combined with intravenous medications to control the infection and provide symptomatic treatment. (Medications should be used under the guidance of a doctor, based on the specific situation.)
