Is there a nebulizer suitable for pneumonia?

Pneumonia is very troublesome. After I feel better from pneumonia, I will have phlegm in my bronchial tubes every time I catch a cold. It feels like it will relapse if I am not careful. My second child has been in the hospital for pneumonia since last year. Like this, the pneumonia was a bit serious at that time, and the inflammation indicators were more than ten times higher. At first, it was a cough. After taking the medicine for two or three weeks, the bronchial tubes were also atomized, but suddenly it became violent one night. See I was in low spirits and sleepy but couldn't sleep because of crying. Then I got a fever in the middle of the night. My intuition was not right and I rushed to the hospital. The doctor said that I had to be hospitalized for pneumonia? Then I did various examinations, injections, atomization, and hospitalization. It took a week before he was discharged from the hospital. When I was discharged from the hospital, I still had phlegm, and the doctor told me to atomize it when I went home, and to take care of it carefully, because many children with pneumonia relapsed if they were not properly cared for at home. Then I bought a nebulizer machine of the same type used in medicine, which is from Germany. At first, I wanted to buy Parry's children's nebulizer from Omron. Because I had a cough, I borrowed it from a friend. But the doctor said that the best model would be better for my child's condition, so I bought it without thinking too much. But the effect of this atomizer is really better than that of my friend. I have atomized it many times before but there is still so much phlegm. With Parry's atomizer, I feel that the phlegm loosens after two or three days of atomization and I can cough up phlegm. It is slower afterwards. Slowly, the phlegm becomes thinner and less, and you can feel the obvious effect. I have had bronchitis, colds and phlegm several times since then, but the effect is still guaranteed. I have been using it for more than a year and it is still good
