- COnly measure peak flow when feeling shortness of breath僅在有呼吸困難時測量尖峰呼氣流量
- DUse the device immediately after taking rescue inhaler在使用急救吸入器後立即測量

尖峰呼氣流量計（Peak Flow Meter）是氣喘病人居家監測病情的重要工具。正確的使用方式是每日固定時間（通常在起床後）進行測量，連續測量三次並記錄最高值（Personal Best），以建立個人基線。若數值下降至黃燈區（個人最佳值的 50-80%）或紅燈區（<50%），需依據行動計畫採取行動或尋求醫療協助，而非僅在症狀出現時才測量。
Accurate peak flow monitoring requires the client to measure their peak expiratory flow rate at the same time daily, typically upon waking, and record the highest of three attempts to establish a reliable personal baseline. Consistent tracking allows for early detection of airflow obstruction, enabling timely intervention based on established asthma action plans rather than waiting for symptom onset.
