Pulmonary Disease and Sleep Medicine

Memphis Sleep Specialists

Our accreditation is through the American Academy of Sleep Medicine. We perform diagnostic and therapeutic polysomnograms as well as multiple sleep latency and maintenance of wakefulness tests. Along with in-lab, overnight testing, we offer home sleep testing when medically appropriate.

Our sleep center staff is proficient in advanced titrations to treat more progressive sleep disorders including central apnea and sleep and obesity-related hypoventilation.

Sleep Disorders

We specialize in the treatment of many sleep disorders in patients age 13 and up, including:

Sleep Apnea/Obstructive Sleep Apnea

Sleep apnea is a disorder of interrupted breathing during sleep. It is usually associated with snoring, choking or gasping, and excessive daytime sleepiness.

Hypoventilation Disorders

Hypoventilation disorders are disorders of shallow breathing during sleep resulting in low oxygen or high carbon dioxide levels. It can be associated with obesity, COPD, and certain neuromuscular conditions such as ALS.


Parasomnias are unusual behaviors that occurring during the sleep period such as sleep walking, night terrors, confessional arousal, sleep eating disorder, REM behavior disorder, and nightmare disorder.


Narcolepsy is neurologic sleep disorder of excessive daytime sleepiness and in some cases is accompanied by the involuntary loss of muscle control know as cataplexy. Cataplexy can occur with emotional stimulus such as laughter, stress, fear, or anger.


Insomnia is a persistent inability to initial and/or maintain sleep. Insomnia can be a result of many factors including poor sleep habits, diet, stress, medical conditions, behavioral and mental health disorders, and even certain medications.

Pulmonary Diseases

Along with sleep disorders, we also treat pulmonary diseases. Listed here are just a few of the respiratory disorders we treat in adult patients age 18 and up.


Asthma is a disease of the lungs in which the airways become blocked or narrowed causing breathing difficulty.


COPD, or chronic obstructive pulmonary disease, is a long-term lung disease that refers to both chronic bronchitis and emphysema.

Shortness of Breath

Shortness of breath is a common symptom of allergy, infection, inflammation, injury, or certain metabolic conditions. Most cases of shortness of breath are due to heart or lung conditions.
