What does ASTD stand for? Definition of ASTD in the Abbreviations.com acronyms and abbreviations directory.
The most certain way to diagnose asthma is with a lung function test, a medical history, and a physical exam. However, it's hard to do lung function tests in children younger than 5 years. Thus, doctors must rely on children's medical histories, signs and symptoms, and physical exams to make a diagnosis. Doctors also may use a 4â6 week trial of asthma medicines to see how well a child responds.
A control pause of 10 seconds denotes severe asthma. Like I said before, his controlled pauses seem like a long time to me and I can't do 60 seconds! The other method to check for hyperventilation is to do a forced test of over breathing. Sit and breathe deeply through your mouth, as if you are running.
