Sleep Medicine


Many of us have experienced trouble sleeping at some point in our lives. But, if sleep problems are a regular occurrence and interfere with your daily life, you may be suffering from a sleep disorder. Our UofL Physicians understand that poor quality sleep can have a negative impact on all areas of your life. Sleeping well is essential to your physical health and emotional well-being. Even minimal sleep loss can take a toll on your mood, energy, efficiency and ability to handle stress. Ignoring sleep problems and disorders can lead to a variety of health ailments, accidents, impaired job performance and relationship stress. If you want to feel your best, stay healthy and perform up to your full potential, sleep is a necessity, not a luxury.

The sleep specialists with UofL Physicians are nationally regarded for their expertise in the diagnosis, treatment and care of sleep disorders. Our mission is to deliver outstanding, state-of-the-art medical care to our patients, with the goal of improving quality of life, as well as preserving and restoring your health. Those sleep problems that manifest as chronic ailments are approached from a chronic disease management standpoint, integrating the social, behavioral, environmental and clinical aspects of chronic disease control.

Treatments & Services

We use a multi-disciplinary approach to sleep disorders, integrating sleep medicine, pulmonary medicine, psychology, neurology, otolaryngology, oral maxillofacial surgery, dental sleep medicine and bariatric surgery. Our specialists are board certified in sleep medicine by the American Academy of Sleep Medicine. We evaluate and treat a wide variety of sleep complaints and disorders.

Diagnostic testing includes:

  • Nocturnal polysomnography with end tidal CO2 monitoring
  • Multiple sleep latency testing
  • Maintenance of wakefulness testing
  • Titration of positive airway pressure as treatment for sleep disordered breathing
  • Nocturnal oxygen titration
  • Actigraphy
  • Initiation and titration of non-invasive mechanical ventilation for patients with chronic respiratory failure including patients with neuromuscular disorders

Treatments we provide include:

Positive Airway Pressure (PAP)

PAP is a mode of respiratory ventilation used in the treatment of sleep apnea. A continuous positive airway pressure (CPAP) machine was initially used mainly by patients for the treatment of sleep apnea at home, but now is in widespread use across intensive care units as a form of ventilation. Obstructive sleep apnea occurs when the upper airway becomes narrow as the muscles relax naturally during sleep. This reduces oxygen in the blood and causes arousal from sleep. The CPAP machine stops this by delivering a stream of compressed air via a hose to a nasal pillow, nose mask, full-face mask or hybrid, splinting the airway (keeping it open under air pressure) so that unobstructed breathing becomes possible, therefore reducing and/or preventing apneas and hypopneas. CPAP treatment can be highly effective in treatment of obstructive sleep apnea. For some patients, the improvement in the quality of sleep and quality of life due to CPAP treatment will be noticed after a single night’s use. Often, the patient’s sleep partner also benefits from markedly improved sleep quality, due to the alleviation of the patient’s loud snoring.

Alternatives to PAP therapy

  • Upper Airway Stimulation: Upper Airway Stimulation is an FDA-approved implantable treatment option for obstructive sleep apnea patients who are unable to use or get consistent benefit from Continuous Positive Airway Pressure (CPAP).  While patients sleep, the implantable device delivers mild stimulation to key airway muscles, allowing the airway to open during sleep.  The patient uses a small handheld remote to turn the device on before bed and off when they wake up.  No mask, no hose, just sleep.  To find out whether you might be a candidate for Upper Airway Stimulation, call the UofL Physicians Sleep Center at 502-588-0480, UofL Physicians – Ear, Nose & Throat at 502-583-3687 or go to
  • Bilevel positive airway pressure (BPAP): Unlike CPAP, which supplies steady, constant pressure to your upper airway as you breathe in and out, BPAP builds to a higher pressure when you inhale and decreases to a lower pressure when you exhale. The goal of this treatment is to assist the weak breathing pattern of central sleep apnea. Some BPAP devices can be set to automatically deliver a breath if the device detects you haven’t taken one after so many seconds.
  • Oral appliances: These are portable devices designed to keep your throat open. PAP is more effective than oral appliances, but oral appliances may be easier for some patients to use. Some are designed to open your throat by bringing your jaw forward, which can sometimes relieve snoring and mild obstructive sleep apnea.
  • Supplemental oxygen: Using supplemental oxygen while you sleep may help if you have central sleep apnea. Various forms of oxygen are available as well as different devices to deliver oxygen to your lungs.
  • Adaptive servo-ventilation (ASV): This more recently approved airflow device learns your normal breathing pattern and stores the information in a built-in computer. After you fall asleep, the machine uses pressure to normalize your breathing pattern and prevent pauses in your breathing. ASV appears to be more successful than CPAP at treating central sleep apnea in some people.
  • Surgery: The goal of surgery for sleep apnea is to remove excess tissue from your nose or throat that may be vibrating and causing you to snore, or that may be blocking your upper air passages and causing sleep apnea. Our Sleep Medicine specialists can refer you to a qualified surgeon in the UofL Physicians network.

Pharmacologic (medication) therapies

A variety of medications can be used to alleviate sleep problems. Our team performs a complete evaluation to determine if this course of treatment is best for you.

Cognitive and behavioral therapies, with a special focus on insomnia

These treatments focus on re-learning how to sleep better. The premise of cognitive behavioral therapy is that changing our thinking leads to change in affect and in behavior. CBT helps individuals replace ineffective coping skills, cognitions, emotions and behaviors with more adaptive ones, by challenging an individual’s way of thinking and the way that he/she reacts to certain habits or behaviors.
