Obstructive Sleep Apnea versus Central Sleep Apnea
Obstructive sleep apnea is when the airwaybecomes narrowed or obstructed and you're making the effort to breathe but we do notsee any flow in air movement coming from your nose or mouth. Where central sleep apnea occurswhere your brain forgets to tell your body to breathe. If we're looking at it from avery simplistic term and so we do not see the drive to breathe. So the first step isto come into the and be seen by one of our physicians in the sleep medicine .We'll go through a questionnaire and try to determine what risk factors we think you havefor sleep apnea such as obesity, snoring, daytime sleepiness and then if we think thatyou have a high risk for meeting those criteria
then we would set you up for a sleep studyeither in your home to do an overnight sleep study or in our laboratory, depending on yoursituation. The CPAP can be used to treat both conditions and, in some patients, that isenough. However, there are some patients that have more complex types of central sleep apneathat require more complicated types of machines to treat that condition. Obstructive sleepapnea actually has been linked to a lot of other problems such as high blood pressureand then, you know, difficulty functioning during the day. If it goes untreated for along period of time there's an increased risk of early heart problems and those types ofthings.
ApneaApp on NSF Science Now
NARRATOR: Sleep apnea is a disease that affectsmore than 25 million Americans, left untreated, can lead to high blood pressure, stroke, heartproblems and diabetes. Current testing for the disease requires a person to wear a tangleof wires, can be costly and often requires sleeping overnight in a strange bed.That's why researchers at the University of Washington have developed ApneaApp, a smartphoneapp that wirelessly tracks changes in a person's breathing movements. To detect the telltalepauses in breathing, the smartphone's speaker sends out an inaudible sound wave, which bounceoff a sleeping person's body and are picked back up by the phone's microphone.
NATHANIEL F. WATSON: The thing about is thatmost people that have it don't know that they have it. ApneaApp is something a person canuse on their phone, in their home sleeping environment, that can give them an indicationto whether or not they may be stopping breathing during their sleep. DENA HEADLEE: The team tested the app on 37patients undergoing sleep apnea studies at a sleep . Researchers put aSamsung Galaxy S4 on a corner of the bed. During nearly 300 hours of testing, the apptracked respiratory events including central apnea, obstructive apnea and hypoapnea with9599 percent accuracy. Tests in a home bedroom
showed ApneaApp works efficiently at distancesof up to 3 feet, in any sleeping position, even when a person is under blankets. By providinga convenient, wireless, noninvasive way for the average person to test at home over thecourse of several nights or weeks, the team feels the ApneaApp could provide a more completepicture of reallife sleeping patterns and lead to treatment. NATHANIEL F. WATSON: ApneaApp is still inthe developmental stages at the moment but we do believe that ApneaApp has a lot of potential.We feel that a very simple way for people to indicate whether or not they have sleepapnea in their home sleeping environment has
tremendous potential to help people live happier,healthier lives. DENA HEADLEE: For more information about thesestories, visit us at NSF.gov. This is NSF Science Now, I'm Dena Headlee. â™ª MUSIC â™ª.

breathing in their sleep when we measure sleep nowwe have people coming to the sleep laboratory typically for one night youcome in your spending about 12 to 14 hours here you get hooked up toa lot of different equipment we put electrodes on patients heads we alsomeasure breeding at the nose and mouth we measure their heart rate measure legmovements we measure respiratory effort you arekinda hooked up to a lot of equipment in a bedroom thing you could think of aperson who's going just going to sleep
he can just done on our at presidentcard but then and then leave the phone on his leg side boardlike just regular how he wouldn't leave it for charging and then keep that that the atoning the Forney Glen active sonarthe concept of them like I've hollaback works for me and make an indictablesignal using the phone speaker and the signals would get reflected ofthe body and its to cart it by the microphone itactually monetize your abdominal breathing motion
and then a guy for defects ideasemotions like leg movement overall body movement except rap men there to people yet actually at different distances fromthe phone so I think no actually could work each have thisdistant into a unique frequently back then in the phone in Article best apnea at be actuallywork at the you'd up high above your sleep lab so be actually place the phone running I apneaat on
like one corner of the back and then becompared to decide which we obtained using I apnea at and or Asian qualify McAfeebest be connected this test for around like40 people and got an activity of about 98 percentand the app is still in the developmental stages at the moment but we do believe that atthe app has a lot of potential we feel that a very simple way forpeople to
indicate whether or not they have sleepapnea in their home sleeping environment has tremendous potential to help peoplelive happier healthier lives.
