Resperate is a portable electronic device that's promoted to achieve slow, deep breathing. The device is approved by the U.S. Food and Drug Administration for reducing stress and lowering blood pressure. It's available without a prescription.
Resperate uses chest sensors to measure breathing, and then sends the real-time information to a small device worn on a belt. The device creates a melody to listen to and synchronize breathing. The melody is supposed to help the user slow breathing with long exhalations.
The computerized musical device called RESPeRATE helps people breathe slowly and lowers their blood pressure, research shows.
"I am happy to say that despite our original expectations, it worked," Elliott tells WebMD. Elliott and colleagues report their findings on the RESPeRATE device in the October issue of The Journal of Clinical Hypertension. InterCure Ltd. funded the study.
Research involving the device has shown that slow breathing (less than 10 breaths a minute) can cause a modest but significant decrease in blood pressure in some people. It's unclear how long the effects last, or if continued use lowers blood pressure even more.
Works in 15 Minutes a Day
RESPeRATE's patented guided breathing technology slows breathing and prolongs exhalation. It relaxes constricted blood vessels leading to lasting, all-day blood pressure reduction within a few weeks.
According to the Japanese Society of Hypertension, taking six deep breaths within 30 seconds significantly reduces blood pressure. This 30-second breathing exercise is a simple and easy way to help manage stress and promote relaxation.
Music, Breathing, and Blood Pressure
The RESPeRATE device has three components. One is a little computerized module the size of a personal CD player. The second is a standard set of earphones. And the third is a chest strap holding a breath sensor.
Patients put the elastic strap around their chest, put on the earphones, and sit in a chair. The device plays soothing music. Incorporated into the music are tones that represent the patient's actual breathing. Patients are instructed to match their breathing to the tones, which gradually slow until a person is breathing at the relaxing rate of 10 breaths per minute.
'Sneaky' RESPeRATE Device Study
Elliott and colleagues asked 149 patients with high blood pressure to use a home blood-pressure monitor. What they didn't tell them was that the study was really a test of the RESPeRATE device.
Along with their blood pressure monitor, about two-thirds of the patients unexpectedly got the RESPeRATE device. The very simple instructions implied that it would help measure and record their blood pressure. Elliott says the study's "sneaky" design limited unwanted influences on blood pressure often seen in other studies of blood pressure treatments.
So what happened? Nearly everyone who got the RESPeRATE device was able to use it correctly. Of the 89 patients who got the RESPeRATE device, 33 used it a lot. They achieved 180 minutes of deep breathing over the eight-week study. Because the RESPeRATE device only gradually lowers breathing rate, they actually used the device for about 15 minutes a day.
These frequent users got a 15 point drop in blood pressure. Even a small, sustained drop in blood pressure can have big health benefits.
In other studies, patients who aggressively monitor their blood pressure usually see a small but significant blood pressure drop. That happened here, too. Monitoring alone resulted in a 9.2 point drop in systolic blood pressure. Adding the RESPeRATE device lowered blood pressure even more.
"Those who got the device -- even though they were not expecting it -- used it correctly," Elliott says. "Those who did were able to lower their blood pressure."
Do You Really Need the RESPeRATE Device?
Why not just sit and breathe slowly while listening to relaxing music? It might work, and a portable CD player is less expensive than a RESPeRATE device. But Elliott says the RESPeRATE device does a lot more than play music.
"The reason the machine might be more helpful is that it is a method of biofeedback that allows you not to have to focus on lowering your breathing rate. It does that for you," Elliott says. "You just follow the tones and do the breathing. Because you don't spend much effort in your muscles or your brain, you will have a better relaxation response -- and some reduction in blood pressure. All those things are tied together."
If you have high blood pressure, see a doctor before trying any over-the-counter treatment, warns Laurence Sperling, MD, director of preventive cardiology at Atlanta's Emory University.
"It is important for anybody with high blood pressure to seek the advice of a doctor in addressing the causes and also treatment approaches," Sperling tells WebMD. "It seems it should be simple and easy - but actually, high blood pressure can be difficult to treat. But this device, for some people, could help them improve their blood pressure."
Sperling notes that he regularly refers high blood pressure patients to psychological services for stress reduction, including biofeedback training.
