My son who is 2.5 years old had fever which passed two days back, pediatrician prescribed azithral and montair lc kid which we are giving him but from today he has started coughing, we went to the doctor and he prescribed budesal and mucomix and asked it to mix it with normal saline, now I do not understand how am I supposed to mix normal saline to budesal and mucomix. I was told to nubulise him separately with both. Please help me to understand the process of nebulization and how am I supposed to mix them in what quantity?
