Can pneumonia cause other severe illnesses in a child?

Hi doctor,

My child is 2 years and 11 months old. He was admitted to the hospital after being diagnosed with bacterial pneumonia. I would like to seek consultation here due to the language barrier with the local doctors. First, I would like to know if we got to the hospital too late. Eight months ago, my child began to cough mildly during the night and in the morning. However, the coughing became more severe the next day and lasted all day. The next day, he developed a high fever of 101.66 degrees Fahrenheit at its peak. We used Nurofen tablets to reduce the fever. However, it reappeared after a few hours. After that, we went to see our family doctor, who diagnosed my child with pneumonia and advised us to go to the emergency room immediately.

He had rapid breathing and a large belly movement on this particular day. He had a blood test and chest radiography, which determined that he had pneumonia. His oxygen level was 92 in the afternoon. He was exhausted all day and wanted to sleep constantly. The oxygen level was 95 after the first two IV antibiotic doses. The next day, his energy seemed to be fine. Not so sleepy as yesterday. He coughed now and then, not very violently. Though the doctor said, it was good to cough up the mucus to recover fast. Based on my description, I would like to know if this appears to be a serious case. Will this pneumonia make him more susceptible to other lung diseases in the future?

Hi doctor,

Thank you for the reply.

Among all the treatments, the doctor gives us an aerosol machine to breathe the vapor of saline water. But my child is adamantly opposed it. Do I have to force him? On the other hand, his breathing appears to be normal. Snores occasionally while sleeping. Mucus does not come out when he sneezes. So I am not sure how congested his nose is.
