Pressure Monitoring Rx information from Jenny Aveson, CVS / Pharmacy, Richmond, Virginia About 33% of Americans have hypertension (high blood pressure), and another 25% have "prehypertension" because their blood pressure is at the high end of normal. Good blood pressure control depends on good measurements. Experts now strongly encourage patients to monitor their own blood pressure in order to avoid the "white coat" effect and get more readings. The average blood pressure better predicts cardiovascular events (heart attack, stroke, etc.). Which type of monitor is best? A blood pressure monitor with a cuff that goes around the upper arm is more accurate than a wrist or finger monitor. Also, digital monitors inflate automatically and are easy to read. Be sure to get a cuff that fits - too small or too large can affect blood pressure by as much as 30mmHg. Some reputable monitor manufacturers are Omron, Lumiscope and LifeSource. Many store brands are made by these same companies and they cost less. Using proper technique to measure blood pressure is essential for an accurate reading. Have the arm rested and at heart level. Diastolic pressure (the "bottom" number) increases by up to 10% when the arm is not supported. Having the arm above or below heart level can throw the reading off by up to 10mmHg. Also, sit with your back supported, feet flat on the floor and upper arm bare (no shirt sleeve). It is best to rest at least 5 minutes before the reading or 30 minutes if you just exercised. Take three readings one minute apart and average them. Caffeine and nicotine can increase blood pressure. Take your reading before using these. Otherwise, wait 30 minutes after nicotine use and a coupe of hours after caffeine. _________________________ Thank you, Central Virginia Post-Polio Support Group, for sharing Jenny’s information.  |
