Adults with coughing pneumonia and a 2+ positive mycoplasma result are generally considered to have community-acquired pneumonia, mycoplasma infection, also known as Mycoplasma pneumonia. A combination of impaired consciousness, age greater than 65 years, respiratory rate greater than or equal to 30 breaths, blood pressure below normal, and blood urea nitrogen greater than 7 mmol per liter in three of the five items suggests that severe pneumonia is more likely. Mycoplasma pneumonia is one of the most common types of pneumonia in the clinic, mostly seen in children. Whether it is severe pneumonia needs to be judged by the combination of whether there is unconsciousness, age greater than 65 years old, respiratory rate is greater than or equal to 30 times, blood pressure is lower than normal, and blood urea nitrogen is greater than 7 millimoles per liter. Mycoplasma infection is recommended to be treated in time to avoid complications such as encephalitis, meningitis, pericarditis, etc. Clinically used antibiotics generally include erythromycin, azithromycin, doxycycline, etc., and the specific use of medication needs to be followed by the doctor’s instructions.
