New York: Accurate blood pressure measurement is critical for diagnosing and managing hypertension, yet many patients, nurses, and even doctors often skip essential steps that ensure precise readings. Factors such as sitting posture, arm positioning, recent caffeine consumption, and even casual conversation during the measurement can significantly impact results, leading to higher or lower-than-normal readings, according to a report by The Wall Street Journal, citing experts and the Xinhua news agency.
Dr. Tammy Brady, a pediatric nephrologist at Johns Hopkins Children's Center, told IANS the importance of precise measurements to improve cardiovascular health outcomes. "To make a meaningful impact on people's cardiovascular health, we need to screen and treat hypertension accurately," Dr. Brady stated. Proper blood pressure readings are vital to preventing severe conditions such as heart attacks and strokes.
The American Heart Association (AHA) offers detailed guidelines for accurate blood pressure measurements. Patients should sit with their feet flat on the ground, legs uncrossed, back straight, and their arm supported at heart level on a stable surface. The cuff should be placed on a bare arm, and the patient should avoid talking, using a phone, or having a full bladder during the measurement. Additionally, blood pressure should be taken multiple times during a single sitting to ensure consistency.
In related developments, recent research highlights the role of exercise in managing hypertension. A study published by the Prospective Physical Activity, Sitting and Sleep (ProPASS) Consortium, led by the University of Sydney and University College London, suggests that as little as five minutes of daily physical activity, such as stair climbing or walking uphill, can help lower blood pressure.
Replacing 20 to 27 minutes of sedentary behavior with moderate-to-high intensity exercise was found to significantly reduce blood pressure, with potential reductions in cardiovascular disease risk by 28 percent. Emmanuel Stamatakis, Director of the ProPASS Consortium, underscored the importance of even brief periods of activity. "The finding that just five extra minutes of exercise daily could lower blood pressure readings highlights the power of short, higher-intensity movements for blood pressure management," he said.
This highlights the dual importance of accurate blood pressure measurement and incorporating physical activity into daily routines for effective hypertension management.
