Sleep Care

Oklahoma Heart Institute Sleep Care

Oklahoma Heart Institute Sleep Care is a premier comprehensive sleep medicine program that follows the standards for practice and accreditation set forth by the American Academy of Sleep Medicine. Our physicians are board-certified in sleep medicine and our testing facilities have state-of-the-art sleep diagnostic testing equipment for diagnosing and treating sleep disorders in both children and adults. We are committed to improving your health and life through the highest quality of sleep services available.

According to the National Heart, Blood, and Lung Institute (NHLBI), approximately one in six, or 40 million Americans, suffer from a sleep disorder. Symptoms of certain sleep disorders include persistent loud snoring, trouble falling asleep, daytime sleepiness, hypertension, restless sleep and gasping for breath during sleep. Untreated sleep disorders can have serious consequences including death, heart attack/stroke, diabetes, depression, reduced quality of life and sexual dysfunction.


Sleep Disorders We Treat

Sleep Apnea

Often associated with loud snoring, snorting and gasping for breath, these are periods of uninterrupted breathing during sleep. Sleep apnea can result in daytime sleepiness which can lead to difficulties at work, cause automobile accidents, memory and other intellectual difficulties and depression. Sleep apnea can lead to worsening high blood pressure and is associated with a higher incidence of heart attacks and strokes.

Are You at Risk for Sleep Apnea?

Sleep apnea can affect anyone at any age, even children. Risk factors include:

  • Being male
  • Being overweight
  • Being over age 40
  • Having a large neck size (17 inches or greater in men and 16 inches or greater in women)
  • Having large tonsils, a large tongue or a small jaw bone
  • Having a family history of sleep apnea
  • Gastroesophageal reflux or GERD
  • Nasal obstruction due to a deviated septum, allergies or sinus problems

Do You Suffer from Sleep Apnea?

  • Most people who have sleep apnea do not know they have it because it only occurs during sleep and it often goes undiagnosed.
  • Sleep apnea is a condition where the airway collapses during sleep, causing pauses in breathing or shallow breaths.
  • Sleep apnea cannot be detected in a routine office visit and there are no blood tests for the condition. This is why your physician may order a sleep study.
  • More than half of the people who have this condition are overweight. There are serious health conditions related to sleep apnea.
  • Treatment for sleep disorders usually improves your overall health and happiness as well as your quality of sleep.

Uncomfortable sensations in the legs near sleep time, leading to an irresistible need to move the legs and interference with falling asleep. Legs and arms may move or jerk involuntarily during sleep. Patients may complain of excessive sleepiness or insomnia, or both.

Nightmares are frightening dreams that arise during REM sleep. They can be caused by stress, anxiety and some drugs.

Circadian rhythm disorders include jet lag, adjustments to shift work, delayed sleep phase syndrome (you fall asleep and wake up too late) and advanced sleep phase syndrome (you fall asleep and wake up too early).

At least 15 percent of the population suffers from insomnia – difficulty falling or staying asleep – every year. Insomnia can be caused by a number of medical or behavioral factors such as stress, anxiety, depression, sleep apnea, restless legs/periodic limb movements during sleep, alcohol, caffeine, drugs or poor sleep habits.

Care for children with sleep disorders demands special expertise. Insomnia, sleepwalking, nightmares, snoring and other sleep-related symptoms are not only a problem for the young patient but for the entire family. Our multidisciplinary approach ensures that the physiological and psychological needs particular to childhood are given thorough and expert attention. For infants, children and adolescents we provide effective diagnostic, treatment and counseling services to aid in the management of sleep problems.


What to Expect at a Sleep Study

When you arrive at one of our sleep clinic locations, you are welcomed by our highly qualified technicians and shown to your comfortable bedroom. The sleep study process will be explained and you will have an opportunity to ask questions. Before the study starts, you will be guided through every step so you are comfortable with the process and your surroundings. As you enter sleep, we will monitor you with our state of the art equipment. A sleep specialist will observe your sleep patterns, brain waves, eye movements, breathing, oxygen levels, heart rate, muscle activity and more with leads attached to your body. While sleeping with multiple sensors might seem difficult, most patients find they fall asleep very easily. If a sleep disorder is discovered, we will work with your referring physician to provide on-going treatment and support.


Contact Information & Locations

Patients should schedule an initial appointment with their primary healthcare provider. If needed, the primary healthcare provider will order the necessary testing through our sleep care staff. We have several sleep lab locations in northeastern Oklahoma.
