尖峰流量計（peak flow meter）用於監測氣喘病人的肺功能變化。使用時需站立以擴大胸腔容積，深吸氣後快速用力吹氣以測得最大吐氣流速。重複測量三次取最高值是為了確保數據精確度。此外，將數據記錄在日記中以觀察長期趨勢，有助於醫師調整治療計畫。不建議在使用救急吸入劑後測量，因為那無法反映氣喘發作的基礎狀態。
Accurate peak flow measurement requires standing upright, inhaling deeply, and blowing out as hard and fast as possible. The test should be repeated three times to record the highest value, and results should be logged to track trends, ideally before using rescue medications.
