氣喘（Asthma）的改善指標主要反映呼吸道阻力的降低與氣體交換的恢復。治療目標為緩解支氣管痙攣與減少發炎分泌物。當呼吸輔助肌不再使用，代表呼吸功（Work of breathing）下降；肺部囉音減少代表氣道通暢；SpO2 上升直接反映氧合改善；尖峰呼氣流量（Peak flow）的提升則是客觀評估氣道阻塞緩解的數據指標。
Indicators of improvement in asthma primarily reflect reduced airway resistance and restoration of gas exchange. The treatment goals are to relieve bronchospasm and reduce inflammatory secretions. Decreased use of accessory muscles indicates reduced work of breathing; clearer lung sounds reflect a patent airway; rising SpO2 directly reflects improved oxygenation; and an increase in peak expiratory flow is an objective measure of relieved airway obstruction.
