尖峰流速計（Peak flow meter）是用於監測氣喘控制狀況的簡易工具。使用流程的準確性至關重要，若未將指針歸零（Reset to zero），前一次的讀數會殘留，導致測量誤差，無法正確評估病人的肺功能變化。護理師需確認病人能正確操作，並理解該數據在氣喘行動計畫（Asthma Action Plan）中的意義。
Accurate peak flow measurements require resetting the indicator to zero before each attempt to ensure precise readings. Failure to reset the device results in residual data from previous efforts, leading to inaccurate assessments of lung function and potential errors in managing the asthma action plan. Proper technique includes standing upright, taking a deep breath, and blowing out as hard and fast as possible.
