尖峰呼氣流速計（Peak Flow Meter）是用於評估氣喘控制程度的關鍵居家工具。正確測量需確保儀器歸零，受試者採取站姿，深吸氣至肺部飽和後，迅速且用力地吐氣至儀器。測量需重複三次，並記錄「最高」數值，而非平均或最低，因為最高值代表病人當下的最佳肺功能。長期記錄能建立個人基準線，幫助病人識別氣喘惡化前兆，及時調整藥物或就醫。
To ensure accurate measurements, the nurse should instruct the client to zero the peak flow meter, take a deep breath, and blow out as hard and fast as possible. The procedure requires repeating the action three times and recording the highest value, as this represents the client's best lung function, while also documenting results in a daily log to track trends.
