7 Steps For Monitoring Your Blood Pressure At Home
(BlackDoctor.org) — Measuring your own blood pressure is a good way to take part in managing your own health and recognizing changes. Your doctor can use your record of measurements to see how well your medicine is working to control your high blood pressure.
Because blood pressure monitors are available widely and without a prescription, home monitoring is an easy step you can take to improve your condition. Before you get started, it’s important to know the right technique and to find a good home blood pressure monitor. This step-by-step guide for using a home blood pressure monitor can help.
Choosing a Monitor
You have the choice of a manual home blood pressure monitor or a digital one. Each has pros and cons, although digital blood pressure monitors are easier to use and to read because readings for both your systolic (when your heart is pumping) and diastolic (when it is at rest) levels flash on the screen. If you own a manual monitor with a manometer (the blood pressure gauge) and stethoscope, practice with a member of your medical team first. If you have a digital monitor, take it to your doctor’s office to make sure it’s calibrated properly.
Step 1: Relax
If you have hypertension, you may need to take your blood pressure at home twice a day — and you’ll want to be relaxed when you do it. Try to take your reading around the same time every day — an hour after you wake up and an hour before bed, for example. Just avoid any stimulants, such as caffeine, tobacco, or alcohol, for at least 30 minutes before a reading. You should also wait 30 minutes after exercising. Finally, empty your bladder before you begin.
Step 2: Take a Seat
Sit down in a comfortable chair next to a desk or table where you can place your home blood pressure monitor. Rest quietly, without talking, for 5 to 10 minutes before you start. Make sure your back is supported, and that your feet are comfortably on the floor with your legs uncrossed. Take your pressure on your non-dominant arm. Lift that forearm to heart level and support it on the desk so it stays comfortably elevated. Open your palm and face it up.
Step 3: Find Your Pulse
Locate your pulse by gently placing your index and middle fingers on the inside of the crease in your elbow. Press down gently and slide your fingers slowly over the area until you feel rhythmic pulsing. This is your brachial artery, the artery that runs from your shoulder to the bend in your elbow. Some digital home blood pressure monitors will tell actually you your pulse rate. If yours does, skip this step.
Step 4: Put on the Cuff
Wrap the cuff around your arm so it’s snug but not too tight. As a rule of thumb, you should be able to slip one finger under the cuff. Place the cuff against your skin, not over your clothing. Lloyd notes not to just push your sleeve up to the top of your arm — doing so forms a tight bend around the upper arm. The bottom of the cuff should be about one inch above the bend, or crease, in your elbow. Look for an arrow or line on the cuff that should be lined up with (or point to) the pulse from your brachial artery.
Step 5: Take Your Pressure
Hold the manometer, in your non-dominant hand. Most models have a built-in stethoscope, but if you’re using a detached one, place it over the spot where you located your pulse. With your dominant hand, hold the bulb and close the valve by turning the screw in a clockwise direction, then squeeze the bulb quickly to inflate the cuff until the indicator in the manometer is about 30 points higher than your expected systolic number — you shouldn’t be able to hear your heartbeat through the stethoscope at this point. Watch the gauge carefully as you slowly open the valve, and remember the number it reads when you hear your first beat; this is the systolic, or top, number of your blood pressure. As you continue to slowly let out the air, look for the number on the gauge at the moment when you no longer hear the beat; this is the diastolic, or bottom, number of your blood pressure. Finish deflating the cuff. A digital blood pressure monitor can be semiautomatic (you pump up the cuff with a bulb) or fully automatic (you press a button to inflate the cuff instead of using a bulb). Follow the manufacturer’s instructions to start the reading. A digital blood pressure monitor will usually beep when it reads your pressure and display the two numbers, your systolic and diastolic pressures, on its screen.
Step 6: Record Your Blood Pressure Numbers
To help you better manage your daily blood pressure readings, write down both your systolic and diastolic pressures and the date and time in a log. Organize your records so both you and your doctor can use them to treat and manage your condition. If a reading seems unusual, you may want to repeat it to be sure. Wait at least a minute, then take off the cuff and start over — don’t just re-inflate it. Some doctors recommend taking two to three readings each time.
Step 7: Store Your Monitor
Keep your home blood pressure monitor in a safe, dry, and cool place, and store it so the tubing isn’t twisted. Check your home blood pressure monitor periodically for cracks or leaks in the tubing. Once a year, take it to your health care provider to see if it needs recalibrating. With guidance and a little practice, you’ll learn how to use your home blood pressure monitor, making this part of managing your hypertension one of the easiest.
HIV Rates For Urban Black Women Five Times Higher Than Previously Estimated
(BlackDoctor.org) — AIDS experts at Johns Hopkins say they are surprised and dismayed by results of their latest multicenter study showing that the yearly number of new cases of HIV infection among black women in Baltimore and other cities is five times higher than previously thought. The data show that infection rates for HIV, the virus that causes AIDS, among this population are much higher than the overall incidence rates in the United States for African-American adolescents and African-American women.
The data come from an ongoing, larger series of studies supported by the HIV Prevention Trials Network, and reflect testing and analysis of at-risk women in six urban areas in the northeastern and southeastern United States hardest hit by the global AIDS epidemic. The so-called “hotspots” are Baltimore; Atlanta; Raleigh-Durham, N.C.; Washington, D.C.; Newark, N.J.; and New York City. Researchers plan to present their findings March 8 at the 19th annual Conference on Retroviruses and Opportunistic Infections in Seattle.
Specifically, the team found that among 2,099 women ages 18 to 44, 88 percent of whom were black, 1.5 percent (32 women) tested positive at the outset of the study, even though they all thought they were negative. Among those who initially tested negative for HIV, the rate of new infections was 0.24 percent within a year after joining the study. Some 215 study participants came from Baltimore.
Experts say this rate of infection, or seroconversion, is five times previous estimates from the U.S. Centers for Disease Control and Prevention overall for African-American women.
“This study clearly shows that the HIV epidemic is not over, especially in urban areas of the United States, like Baltimore, where HIV and poverty are more common, and sexually active African-American men and women are especially susceptible to infection,” says principal investigator for the Baltimore portion of the study, Charles Flexner, M.D., a clinical pharmacologist and infectious disease expert at Johns Hopkins.
“We, as care providers and policy makers, have our job cut out for us in devising HIV prevention programs targeted to sexually active men and women in Baltimore and other cities,” says Flexner. He says prevention tactics should include more counseling about sexually transmitted infections, distribution of condoms, and intensive education about safer sex practices. Flexner is a professor at the Johns Hopkins University School of Medicine and the university’s Bloomberg School of Public Health.
In Baltimore, the study conducted from May 2009 to July 2010 asked participating women about their safe sex practices and other health issues, then asked them to come to The Johns Hopkins Hospital for HIV testing at no cost. Those who tested positive were offered counseling and treatment, and followed for the duration of the study.
“While we have always known that African-Americans had a higher risk of HIV infection than other American racial groups, this study confirms it and underscores the severity of the national and local problem, especially in cities,” says study site leader was co-investigator Anne Rompalo, M.D., Sc.M., an infectious disease specialist and professor at Johns Hopkins.
Rompalo says women of all races account for a quarter of the 50,000 new HIV infections each year in the United States, which adds to the more than 1 million men and women already known to have tested positive. Sixty-six percent of the women newly infected each year are black, even though African-American women represent only 14 percent of the U.S. female population. The national age-adjusted death rate for black women in the United States is nearly 15 times higher than that observed for HIV-infected white women.
The new study, formally known as HPTN 064 Women’s Seroincidence Study, ended in February 2011 and was funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health.
