How to Measure Blood Pressure Correctly

Measuring blood pressure accurately is essential for monitoring cardiovascular health and managing conditions like hypertension. Proper technique ensures reliable readings and helps avoid misleading results. Here are the key steps and best practices to follow when measuring blood pressure:

Choose the Right Placement for the Blood Pressure Cuff

Place the blood pressure cuff on the upper arm, just above the elbow joint, rather than on the wrist. This is especially important for elderly patients who may have more advanced arterial hardening. In such cases, the radial artery in the wrist may have weaker pulsations, making it less reliable for accurate readings. Measuring at the elbow provides a more consistent and precise result.

Follow a Consistent Daily Routine

According to the latest medical guidelines, individuals should measure their blood pressure twice a day for the most accurate tracking. The first measurement should be taken in the morning right after waking up but before getting out of bed. The second reading should be taken in the evening, ideally before dinner. Maintaining a consistent schedule helps capture a realistic picture of daily blood pressure fluctuations.

Ensure Proper Cuff Positioning and Device Alignment

When applying the cuff, position it approximately 1 cm above the elbow joint. It's also crucial to keep the blood pressure monitor at the same level as the heart during measurement. To achieve this, the patient should sit comfortably with their arm resting on a flat surface, ensuring alignment with the heart. If using an automatic device, allow it to inflate on its own. For greater accuracy, take two readings and calculate the average.

Address White Coat Hypertension and Anxiety-Related Spikes

Some individuals experience elevated blood pressure in clinical settings due to anxiety, a phenomenon known as "white coat hypertension." In these cases, 24-hour ambulatory blood pressure monitoring can provide a comprehensive overview of blood pressure throughout the day and night. Additionally, patients can learn to monitor their own blood pressure at home, where they feel more relaxed and comfortable, leading to more accurate and representative readings.
