My 4 year kid has been suffering from asthma and every year we end up in the hospital with something that has been complicated by asthma. We have attended the asthma clinic and learned ways to prevent attacks, what triggers attacks etc. I thought I was on top of the asthma until our emergency visit and then I started thinking there was probably a lot more to learn than I knew. This is such a terrible thing for anyone to have, especially children.
Few days back we went to physician to check my kid's asthma level and he adviced us to take a test called exhaled nitric oxide(eNO) test to monitor my kid's asthma level. Even I am an asthma patient and I have not heard about this eNO test so far in my life. First time I have heard about this and I am not satisfied with the answer given by my doctor.
What is this eNO test for? Is it a similar kind of test like Pulmonary Function Test? Can you give me some information about this eNO test?
