Dr. Zhong Yuxun reply Cardiology

Hello Shean,
1.
Blood pressure monitors should be calibrated once a year, and this calibration must be performed by the Bureau of Standards, Metrology and Inspection.
There are specific times and locations for calibration each year, which can be inquired about through the health department.

2.
Blood pressure measures the pressure in the arteries during the contraction and relaxation phases of the heart, so hypertension generally refers to arterial hypertension.

3.
Blood pressure is determined by cardiac output and peripheral vascular resistance, and it is not related to topography.

4.
There are many causes of hypertension, which are related to diet, weight, exercise, and emotional factors; bloodletting may only be partially effective for hypertension.
Long-term management through a low-sodium diet, weight control, regular exercise, and adequate sleep is more effective.

Sincerely, Dr.
Chung Yu-Chuan, Director of the Cardiology Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Hypertension, commonly known as high blood pressure, is a prevalent health issue that affects millions of people worldwide. Understanding its causes, measurement, and management is crucial for maintaining overall health. Let's delve into your questions regarding hypertension.

1. Where to Calibrate a Blood Pressure Monitor?
Blood pressure monitors can be calibrated at various locations, including medical clinics, hospitals, or pharmacies that offer health services. It's essential to ensure that your device is accurate, as incorrect readings can lead to mismanagement of your blood pressure. Many pharmacies have trained staff who can assist in calibrating your device. Additionally, some manufacturers provide guidelines on how to check the accuracy of your monitor against a standard device.

2. What is Arterial Hypertension?
Arterial hypertension refers to the condition where the blood pressure in the arteries is persistently elevated. It is often categorized into two types: primary (essential) hypertension, which has no identifiable cause, and secondary hypertension, which results from an underlying condition such as kidney disease or hormonal disorders. The term "arterial hypertension" is often used interchangeably with "high blood pressure," but it specifically emphasizes the involvement of the arteries.

3. Does Blood Pressure Increase at Higher Altitudes?
Yes, blood pressure can be higher at elevated altitudes. When you ascend to higher altitudes, the body experiences lower oxygen levels, which can lead to physiological changes, including increased heart rate and blood pressure. This response is part of the body’s mechanism to ensure adequate oxygen delivery to tissues. If you are monitoring your blood pressure in mountainous areas, it is not uncommon to see elevated readings compared to those taken at sea level.

4. Is Bloodletting Effective for High Blood Pressure?
Bloodletting is an ancient practice that is not recommended for managing hypertension today. While it was historically believed to help with various ailments, modern medicine has shown that effective management of high blood pressure involves lifestyle modifications and medication rather than bloodletting. If your blood pressure exceeds normal levels, it is crucial to consult a healthcare professional for appropriate interventions. They may recommend dietary changes, increased physical activity, stress management techniques, and possibly antihypertensive medications.

Additional Management Tips for Hypertension:
- Lifestyle Modifications: Adopting a heart-healthy diet, such as the DASH (Dietary Approaches to Stop Hypertension) diet, can significantly lower blood pressure. This diet emphasizes fruits, vegetables, whole grains, and lean proteins while reducing sodium intake.

- Regular Exercise: Engaging in regular physical activity, such as brisk walking, swimming, or cycling, can help lower blood pressure and improve overall cardiovascular health.

- Weight Management: Maintaining a healthy weight is crucial, as excess weight can contribute to high blood pressure. Even a modest weight loss can have a significant impact on blood pressure levels.

- Limit Alcohol and Tobacco Use: Reducing alcohol consumption and quitting smoking can improve heart health and lower blood pressure.

- Stress Management: Chronic stress can contribute to hypertension. Techniques such as mindfulness, meditation, and yoga can help manage stress levels effectively.

Conclusion:
Hypertension is a manageable condition with the right approach. Regular monitoring, understanding the factors that influence blood pressure, and making lifestyle changes can significantly improve your health outcomes. If you have concerns about your blood pressure readings or management strategies, it is essential to consult with a healthcare provider who can offer personalized advice and treatment options.
