The 4 stages of status asthmaticus are based on ABG progressions in status asthma. Patients in stage 1 or 2 may be admitted to the hospital, depending on the severity of their dyspnea, their ability to use accessory muscles, and their PEF values or FEV1 after treatment (>50% but < 70% of predicted values).
