Step 1: Use the stepwise classification of chronic asthma, where escalating symptom burden moves a patient from intermittent up to severe persistent.
Step 2: This patient reports multiple daytime episodes plus night-time attacks, indicating symptoms essentially throughout the day with daily nocturnal awakenings.
Step 3: That degree of frequency matches severe persistent asthma, where reliever use is several times daily, daily activity is markedly restricted, and spirometry shows FEV1 under 60 percent predicted with a reduced FEV1/FVC.
Step 4: The lower categories simply do not reach daily-and-nightly frequency, so mild intermittent, mild persistent, and moderate are all eliminated.
