Sleep Care

The Oklahoma Heart Institute Sleep Care at Hillcrest Hospital Cushing is located in a state-of-the-art facility and is one of the finest centers of its kind in the state of Oklahoma. Our full-time staff of physicians and sleep specialists utilize the latest technology for diagnosing and treating sleep disorders in both children and adults.

Evaluation and diagnosis should only be performed by a team of professionals led by a physician with specialized training in sleep disorders. The Hillcrest Hospital Cushing Sleep Study Center recognizes the importance of the unique specialty of Sleep Medicine and offers a full range of evaluation and treatment resources for patients of all ages.

Sleep specialists from the fields of Pulmonary Medicine, Internal Medicine, Neurology, ENT Surgery and Psychiatric resources are available through Oklahoma Heart Institute Sleep Care.

The sleep test most patients undergo is called a Polysomnogram. This test determines whether there are any abnormalities in the patient’s quality of sleep, including breathing abnormalities or limb movements. In most cases, the test is performed during a 10-12 hour, overnight period.

For some patients, a daytime procedure that measures the degree of sleepiness (the Multiple Sleep Latency Test) may also be necessary.

Referral Procedures

Typically, patients schedule appointments, for initial consultation, with their primary care physician, who orders necessary testing through our sleep study staff.

Private consultations are available by appointment with Dr. Jeremy Cole, Board Certified in Sleep Medicine, on Fridays.

For appointments call 918-747-5337 (Option 1)

Sleep Disorders We Treat

Sleep Apnea

Periods of uninterrupted breathing during sleep. Often associated with loud snoring, snorting and gasping for breath. Sleep apnea can result in daytime sleepiness (leading to difficulties at work or even 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.

Restless Legs Syndrome/Periodic Limb Movement Disorder

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.


A brain disorder that causes uncontrollable bouts of excessive sleepiness. Patients with narcolepsy may lose muscular strength suddenly when emotionally upset or when laughing. In addition, they may experience vivid hallucinations as they fall asleep.

Disorders In Children

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. At the Hillcrest Hospital Cushing Sleep Study Center, 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.


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.
