血壓計主要分為水銀柱式、氣壓表式和電子式三種類型。傳統醫療機構主要使用水銀柱式血壓計，測量精確，但操作較為複雜，需要專業知識。氣壓表式血壓計使用氣壓表讀取數據，同樣需要專業操作，較少用於家庭使用。相比之下，電子血壓計操作簡單，測量結果以數字顯示，方便讀取和理解，更適合家庭使用。

在選擇血壓計時，還需要考慮臂式、腕式和手指式三種不同的測量方式。臂式血壓計測量結果最為準確，適合大多數人使用，尤其是有血液循環障礙的人群。腕式血壓計攜帶方便，但對於患有動脈硬化等血管疾病者，測量結果可能不太準確。手指式血壓計最不常見，測量精度最低，僅適用於特殊情況。

選擇顯示清晰、字體大的血壓計，特別適合老年人或視力較差的人使用。某些型號還配備背光顯示，方便在光線不足的環境下使用。

根據手臂的周長選擇合適的臂帶，確保測量的準確性。有些血壓計提供可調臂帶，適合不同體型的使用者。

質量好的血壓計在測量時噪音低，不會對使用者造成困擾。某些型號還具備靜音模式，適合在安靜環境中使用。

單組記憶適合個人使用，多組記憶適合家庭成員共同使用。某些血壓計可以記錄多次測量結果，並生成趨勢分析報告。

提醒用戶在操作過程中的不當行為，確保測量結果的準確性。當測量到異常血壓數值時，自動發出警告，提醒用戶注意健康狀況。

定期校準血壓計很重要，以確保測量數據的準確性。有些免校準型血壓計可以減少用戶的維護成本和麻煩。

1. 將手平放在桌面。若使用上臂式血壓計，應將臂帶圍繞手臂並綁好，臂帶與手肘位之間留有約 2 厘米距離；若使用手腕式血壓計，應將腕帶圍繞手腕並綁好，佩戴方向應能讓自己看見機身的按鈕及屏幕，腕帶與手掌底部之間留有約 1 至 1.5 厘米距離。

2. 臂帶或腕帶的位置，必須與心臟處於同一水平。若臂帶或腕帶的位置低於心臟水平位，血壓讀數將會顯示比實際的高。

3. 佩戴好臂帶或腕帶後，放鬆用來量度血壓的手，掌心向上，用另一隻手按鈕啟動血壓計。量度血壓期間，切勿移動身體或說話，如有其他人協助佩戴及操作將更理想。

Blood pressure monitors are mainly divided into three types: mercury column, aneroid, and electronic. Traditional medical institutions primarily use mercury column blood pressure monitors, which are highly accurate but more complex to operate and require professional knowledge. Aneroid blood pressure monitors use an aneroid gauge to read the data, also requiring professional operation, and are less commonly used in home settings. In comparison, electronic blood pressure monitors are easy to operate, display the measurement results digitally, and are more convenient to read and understand, making them more suitable for home use.

When choosing a blood pressure monitor, you also need to consider the three different measurement methods: arm, wrist, and finger. Arm-type blood pressure monitors provide the most accurate results and are suitable for most people, especially those with circulatory disorders. Wrist-type blood pressure monitors are more portable, but the measurement results may not be as accurate for those with arterial diseases such as arteriosclerosis. Finger-type blood pressure monitors are the least common and have the lowest measurement accuracy, suitable only for special circumstances.

Choose a blood pressure monitor with a clear, large-font display, especially suitable for the elderly or those with poor vision. Some models also have backlit displays, making them convenient to use in low-light environments.

Select a cuff size that fits your arm circumference to ensure the accuracy of the measurement. Some blood pressure monitors offer adjustable cuffs to accommodate different body types.

High-quality blood pressure monitors have low noise levels during measurement, which will not disturb the user. Some models also have a silent mode, suitable for use in quiet environments.

Single-user memory is suitable for individual use, while multi-user memory is suitable for family members to share. Some blood pressure monitors can record multiple measurement results and generate trend analysis reports.

Reminding users of improper operation during the process to ensure the accuracy of the measurement results. When detecting abnormal blood pressure values, it automatically issues a warning to alert the user to their health condition.

Regular calibration of the blood pressure monitor is important to ensure the accuracy of the measurement data. Some self-calibrating blood pressure monitors can reduce the user's maintenance costs and hassle.

1. Place your arm on a table. If using an upper arm-type blood pressure monitor, wrap the cuff around your arm and secure it, leaving about 2 cm of space between the cuff and the elbow. If using a wrist-type blood pressure monitor, wrap the cuff around your wrist and secure it, with the display facing you and about 1 to 1.5 cm of space between the cuff and the base of your palm.

2. The cuff or wrist strap must be at the same level as your heart. If the cuff or wrist strap is lower than your heart level, the blood pressure reading will be higher than the actual value.

3. After securing the cuff or wrist strap, relax the hand used for the measurement, with the palm facing up, and use your other hand to activate the blood pressure monitor. During the measurement, do not move your body or speak. Having someone else assist with the fitting and operation would be ideal.
