Could status asthmaticus be the first presentation of asthma in child?

Possibly: Asthma is a chronic inflammatory condition of the lung. Typically the symptoms consist of cough, shortness of breath and wheezing. These symptoms can be mild and intermittant or severe and life threatening. There is no way to predict who and when the symptoms of asthma could be life threatening.

Yes: A severe asthma attack (status asthmaticus) could certainly be the first presentation of asthma in a child.

Sometimes: Yes a child can present for the first time in status but most often they present mildly.
