New Device Helps Obstructive Sleep Apnea

UMC published the following story authored by Ruth Cummins.

Susan Walters didn’t realize how much sleep she wasn’t getting until her University of Mississippi Medical Center specialist team gave her the therapy to get a full night of restful slumber.

Since the late 1990s, Walters said, “I was waking up several times a night, gasping for breath and snoring. I didn’t think there was anything to it, and that everybody snores.”

Her sister thought otherwise. “She was using a CPAP mask, so I got tested for one,” Walters said of continuous positive airway pressure, a ventilator therapy for sleep apnea patients that uses mild air pressure delivered through a mask to keep airways open.

The CPAP wasn’t for Walters; much newer technology offered by an implant that uses a gentle electric pulse to open up her airway was. “I thought I was sleeping, but I’d get up and feel like I hadn’t rested at all,” she said of the CPAP. “The machine cord was inconvenient when I turned over in the bed. I used a chin strap, and I had to keep my mouth closed and breathe through my nose. It was difficult.”

Walters coped with obstructive sleep apnea, a condition in which a person suffers disrupted sleep and low blood oxygen levels because their tongue is sucked against the back of their throat. That blocks their upper airway, often causing the patient to snore, be unusually sleepy during the day, and sometimes suffer cardiovascular problems, depression or loss of concentration.

Trying to better troubleshoot the problem, 77-year-old Walters underwent a sleep study conducted by Dr. Allen Richert, division chief in the UMMC Department of Psychiatry and Human Behavior and medical director of UMMC’s Sleep Center, located at Select Specialty Hospital in north Jackson.

The majority of studies involve patients spending the night at the Sleep Lab so that their breathing, snoring, movement and oxygen levels can be monitored. Some patients, though, take part in an in-home study that records air flow, oxygen levels and chest movement.

Richert said that the large majority of the sleep studies performed at UMMC are to determine if a patient has obstructive sleep apnea. The most common treatment is CPAP or a newer version of that machine that adjusts during the night. “If the machine notes apnea, it will increase the air pressure on its own,” Richert said.

Richert suggested Walters visit Dr. Andrea Lewis, an associate professor in the Department of Otolaryngology and Communicative Sciences. Lewis determined that Walters was a candidate for a sleep therapy device that delivers mild stimulation to the hypoglossal nerve that controls movement of the tongue and some airway muscles. How much stimulation can be controlled by up and down buttons on a small, hand-held remote control.

Lewis implanted the small device in Walters’ chest as an outpatient procedure, then activated it about a month later after giving the three small incisions time to heal. Walters said she felt immediate relief.

“I was surprised the first time that it worked,” Walters said. “I felt so different when I got up in the morning. I was rested and could stay up later without being drowsy the next day. I realized what I hadn’t been getting all those years.”

The FDA-approved device, designed to provide long-term relief, has a battery life of about 11 years. It works inside the body to address the root causes of obstructive sleep apnea, Lewis said. An electrical impulse delivered to the tongue via a coil running from the hypoglossal nerve to a battery acts much like a pacemaker, she said. A sensor placed between the muscles in the rib area detects when the patient takes a breath, activating a gentle pulse that opens the airway.

“The patient uses a remote control to turn the device on before they go to sleep, and off again after they get up,” Lewis said. “It takes about 30 minutes for it to start working,” which gives the patient time to fall asleep, she said.

The patient hears two beeps when they turn on the remote and a green light shows to indicate it’s been activated, Lewis said. “The patient feels a single pulse on their tongue when it connects,” she said. Patients turn off the device by pressing a gray button, then listening for two beeps. “A status ring on the remote will turn white,” Lewis said.

Walters is among the first patients to receive the implant surgery from Lewis, who began performing it in 2017. Lewis works with patients to find the right setting to give them the best sleep. “You can step up the setting by one level to increase the stimulation, or you can step down if it feels uncomfortable,” she said.

Most patients tend to slowly increase the stimulation during the first two months of use “until they aren’t snoring, or feel that they are sleeping better,” Lewis said. “Some people feel like they get so much benefit that they don’t turn it any higher, but when they have a follow-up sleep study, the find that they could use more.

“The purpose is to find the setting that gives you comfortable sleep,” Lewis said.

UMMC’s sleep team strives to find a solution for all patients, whether it’s the device implanted by Lewis; surgery ranging from removal of tonsils to the more uncommon breaking of the patient’s jaw to move it forward and stretch the face; to CPAP or the use of mouthpieces that hold the mandible forward and mouth closed.

And, weight loss is an important treatment, Richert said. “As the body mass index goes up, the incidence of sleep apnea goes up,” Richert said. “It’s becoming more common. We’re more aware of it.”

Lewis has performed 30-plus procedures, more than any other provider in the state. Lewis has served on the American Academy of Otolaryngology’s national sleep committee and holds certification in sleep medicine from the American Board of Sleep Medicine. UMMC is an ABSM-accredited sleep center.

She’s collecting data at the Medical Center as part of her committee duties. “I was on staff at the University of Pittsburg when this device was originally researched,” said Lewis, who also is a member of the American Academy of Sleep Medicine.

Walters said the device, manufactured by Inspire Medical Systems Inc., has helped her both physically and mentally. The mother of three grown daughters, Walters retired to Clinton after working for 21 years at an insurance company in Ohio.

“I’d fall asleep, but I’d be back up about an hour and a half later with the CPAP,” she said. “Then I’d fall asleep in my chair. This was such a big change.

“I should have done this long ago. I mostly did it to please my sister, but once I found out what a difference it made … She was right.”

I think I just as soon snore-

@3:33Pm. Not if you had obstructive sleep apnea. Unless you have it you don't know.

I love my cpap would be nice to think a simple medical device could replace it and allow me to be untethered. thanks for the post

I don't mind her snoring that much. It's the sleep farting that bothers me. A lot. Is there an implant for that???

Bill Dees is right. My CPAP is 'bout dang my best friend.

@3:33 p.m.- yeah, until your left ventricle enlarges and you develop atrial fibrillation as a result and end up in the ER with congestive heart failure and an ejection fraction of 10%. Keep snoring though

Hasn't it be proven time after time that most of these sleep related issues are due to the fact we are "fat-asses"? For heavens sake people...make better choices!

Doctur Payne said...

As with cancer and hundreds of thousands who would be put out of work if a cure were to be found (so they spin wheels and ask for donations), I'm surprised these people actually WANT to find a simple fix. Think of the people in factories, clinics and other assorted venues who would lose their jobs. This is medical related, people! Do you actually believe people working in hospitals and medical research actually want to discover cures or cheaper, less intrusive treatment methodology? Think. Think.

And they've just now invented a device that will rid your CPAP of mold, snot and mildew and keep it dry and sparkling for your nightly entrapment protocol.

@ 5:30 - I gotta pee three times a night any way. I'd just as soon be awake when I do that, so the 'getting woke' don't bother me none.

The 'Fart Comment' @ 4:38 for the win. There ain't nothin' worse than a bed-made who farts all night 'cept for getting up and peein' but not in that order.

There’s also an old device for sleep apnea that works. It’s called exercise.

Anonymous said...

This device is not new, its about 10 years old. It cost around $20,000 and insurance will fight tooth and nail to not pay for it. You also have to have tried and failed CPAP before they will begin looking at this device. CPAP is the best choice for 90% of the people suffering from sleep apnea. Most people love their CPAP, I know I love mine.

@7:50 a.m.- Negative, you cannot exercise away obesity- it is 90% diet. Does exercising have benefits? Of course, however weight loss isn't one of them. If we stuck to unprocessed, real foods(meat and veggies and even minimally processed grains in metabolically healthy persons) and eliminated sugar, most of our obesity(and chronic health issues encompassing obesity) would be a thing of the past.

Leech Salesman said...

Bull Shit! I know many skinny, fit people who either use CPAP or their mate complains that they snore. Just as I know 30 year old marathon runners who have heart stents.

Teaching hospitals teach many things...among them, how to prepare a resume if cures make your job obsolete.

I love my CPAP! Its been a game changer for me, and I am not obese. I am not fat by any measure. I just started snoring in my mid 40s, got diagnosed and got my CPAP.

I am not overweight at all. But I broke my nose as a teenager playing football. Since then I just don't breathe through my nose very well. So when I get horizontal, I really struggle. The CPAP machine opens my airways and allows me to breathe nice and easy. It has been wonderful and has been life-changing. I wouldn't want to live without it.

10:37 Stupidity should be painful. The spouse has lost and kept off about 150 pounds since hitting the gym regularly about 5 years ago. What excess calories you don't burn get stored as fat, unless they have repealed the Second Law of Thermodynamics.

Trollfest '09

Trollfest '07 was such a success that Jackson Jambalaya will once again host Trollfest '09. Catch this great event which will leave NE Jackson & Fondren in flames. Othor Cain and his band, The Black Power Structure headline the night while Sonjay Poontang returns for an encore performance. Former Frank Melton bodyguard Marcus Wright makes his premier appearance at Trollfest singing "I'm a Sweet Transvestite" from "The Rocky Horror Picture Show." Kamikaze will sing his new hit, “How I sold out to da Man.” Robbie Bell again performs: “Mamas, don't let your babies grow up to be Bells” and “Any friend of Ed Peters is a friend of mine”. After the show, Ms. Bell will autograph copies of her mug shot photos. In a salute to “Dancing with the Stars”, Ms. Bell and Hinds County District Attorney Robert Smith will dance the Wango Tango.

Wrestling returns, except this time it will be a Battle Royal with Othor Cain, Ben Allen, Kim Wade, Haley Fisackerly, Alan Lange, and “Big Cat” Donna Ladd all in the ring at the same time. The Battle Royal will be in a steel cage, no time limit, no referee, and the losers must leave town. Marshand Crisler will be the honorary referee (as it gives him a title without actually having to do anything).

Meet KIM Waaaaaade at the Entergy Tent. For five pesos, Kim will sell you a chance to win a deed to a crack house on Ridgeway Street stuffed in the Howard Industries pinata. Don't worry if the pinata is beaten to shreds, as Mr. Wade has Jose, Emmanuel, and Carlos, all illegal immigrants, available as replacements for the it. Upon leaving the Entergy tent, fig leaves will be available in case Entergy literally takes everything you have as part of its Trollfest ticket price adjustment charge.

Donna Ladd of The Jackson Free Press will give several classes on learning how to write. Smearing, writing without factchecking, and reporting only one side of a story will be covered. A donation to pay their taxes will be accepted and she will be signing copies of their former federal tax liens. Ms. Ladd will give a dramatic reading of her two award-winning essays (They received The Jackson Free Press "Best Of" awards.) "Why everything is always about me" and "Why I cover murders better than anyone else in Jackson".

In the spirit of helping those who are less fortunate, Trollfest '09 adopts a cause for which a portion of the proceeds and donations will be donated: Keeping Frank Melton in his home. The “Keep Frank Melton From Being Homeless” booth will sell chances for five dollars to pin the tail on the jackass. John Reeves has graciously volunteered to be the jackass for this honorable excursion into saving Frank's ass. What's an ass between two friends after all? If Mr. Reeves is unable to um, perform, Speaker Billy McCoy has also volunteered as when the word “jackass” was mentioned he immediately ran as fast as he could to sign up.

In order to help clean up the legal profession, Adam Kilgore of the Mississippi Bar will be giving away free, round-trip plane tickets to the North Pole where they keep their bar complaint forms (which are NOT available online). If you don't want to go to the North Pole, you can enjoy Brant Brantley's (of the Mississippi Commission on Judicial Performance) free guided tours of the quicksand field over by High Street where all complaints against judges disappear. If for some reason you are unable to control yourself, never fear; Judge Houston Patton will operate his jail where no lawyers are needed or allowed as you just sit there for minutes... hours.... months...years until he decides he is tired of you sitting in his jail. Do not think Judge Patton is a bad judge however as he plans to serve free Mad Dog 20/20 to all inmates.

Trollfest '09 is a pet-friendly event as well. Feel free to bring your dog with you and do not worry if your pet gets hungry, as employees of the Jackson Zoo will be on hand to provide some of their animals as food when it gets to be feeding time for your little loved one.

Relax at the Fox News Tent. Since there are only three blonde reporters in Jackson (being blonde is a requirement for working at Fox News), Megan and Kathryn from WAPT and Wendy from WLBT will be on loan to Fox. To gain admittance to the VIP section, bring either your Republican Party ID card or a Rebel Flag. Bringing both and a torn-up Obama yard sign will entitle you to free drinks served by Megan, Wendy, and Kathryn. Get your tickets now. Since this is an event for trolls, no ID is required. Just bring the hate. Bring the family, Trollfest '09 is for EVERYONE!!!

This is definitely a Beaver production.
