What is the preferred technique for measuring an adult's blood pressure?

The preferred technique for measuring an adult's blood pressure is to do so manually with a sphygmomanometer and stethoscope. This method provides the most accurate readings and is the gold standard in clinical practice.

When using a manual sphygmomanometer, the healthcare provider can carefully observe the sounds of the blood flow through the artery, known as Korotkoff sounds, which allows for precise determination of both systolic and diastolic pressures. The ability to hear and interpret these sounds is critical to accurately gauge blood pressure, especially in cases where the patient may have conditions that affect blood flow or in non-standard situations.

While digital monitors and automatic inflate devices are convenient and can yield accurate results, they may not always perform as reliably in all patient populations or conditions, such as in patients with arrhythmias. Additionally, digital devices might require calibration or have limitations under certain circumstances. Measuring in a sitting position is helpful but is not as critical as the technique used; blood pressure can also be measured accurately when the patient is lying down or standing, as long as appropriate positioning is ensured.

Thus, the manual technique is preferred for accuracy, allowing for better clinical assessment and management of blood pressure in adults.
