如何正確量血壓

以下依台灣高血壓學會推廣的「722原則」整理，供居家量測參考。本頁為一般衛教資訊，不能取代醫師的專業判斷。

什麼是 722

連續 7 天
每天早晚各 2 回
每回量 2 次，中間間隔約 1 分鐘，取平均

量測前

前 30 分鐘不要抽菸、進食、喝酒、咖啡或茶
不要運動或洗澡
先上廁所排尿

量測姿勢

坐在有靠背的椅子上，背靠著椅背
雙腳平放著地，不要翹腳
靜坐休息 5 分鐘，過程中不說話
手臂放鬆置於桌面，與心臟同高
壓脈帶鬆緊約可伸入一根手指

量測中

不說話、不移動
每回量 2 次，間隔約 1 分鐘，取平均值記錄

什麼時候量

早上：起床後、服藥與早餐之前
晚上：睡前
早晚各一回，連續量測多天

其他注意事項

固定使用同一隻手臂。若兩手數值差異大，固定用數值較高的那一隻
血壓計需要定期校正
單次數值偏高不代表有高血壓，趨勢比單筆數字更重要

How to Measure Blood Pressure Correctly

The following is based on the "722 principle" promoted by the Taiwan Hypertension Society, as a reference for home measurement. This is general health information and cannot replace professional medical advice.

What 722 means

7 days in a row
2 sessions each day, morning and evening
2 readings per session, about 1 minute apart, then take the average

Before measuring

No smoking, food, alcohol, coffee, or tea for 30 minutes beforehand
Do not exercise or bathe beforehand
Empty your bladder first

Posture

Sit in a chair with a backrest, with your back against it
Keep both feet flat on the floor; do not cross your legs
Rest quietly for 5 minutes, without talking
Rest your arm on the table, relaxed and level with your heart
The cuff should be snug enough that one finger fits underneath

While measuring

Do not talk or move
Take 2 readings about 1 minute apart, and record the average

When to measure

Morning: after getting up, before medication and breakfast
Evening: before going to bed
One session each morning and evening, over several consecutive days

Other things to keep in mind

Always use the same arm. If the two arms differ noticeably, always use the one with the higher readings
Blood pressure monitors need to be calibrated periodically
A single high reading does not mean you have hypertension — the trend matters more than any one number
