What is OSA?

Obstructive Sleep Apnea (OSA) affects 22 million Americans.  OSA occurs when soft tissues in the airway collapse during sleep and block the flow of oxygen to the brain.  The brain senses a lack of oxygen and wakes the body up just long enough to take a breath, then the body falls back asleep.  This cycle repeats throughout the night and causes poor, disruptive sleep.  When left untreated, OSA can cause vehicle and workplace accidents, worsening mood and memory, stroke, heart attack and even death.

Treatments & Services

Continuous Positive Airway Pressure (CPAP)

Continuous Positive Airway Pressure (CPAP) is the most commonly used treatment for OSA.  CPAP is a mode of respiratory ventilation that uses a mask and hose to blow pressurized air into the airway to keep it open during sleep.  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 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 ill 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.

Upper Airway Stimulation 

Upper Airway Stimulation may be an option for patients who:

  • Have moderate to severe obstructive sleep apnea
  • Are unable to use or get consistent benefit from CPAP
  • Are not significantly overweight
  • Are over the age of 22

Upper Airway Stimulation is an FDA-approved implantable treatment option for obstructive sleep apnea patients.  While patients sleep, the implantable device monitors the patient’s every breath.  Based on the patient’s unique breathing patterns, the system delivers mild stimulation to the hypoglossal nerve, which controls the movement of the tongue and other key airway muscles.  By stimulating these muscles, the airway remains open during sleep.  The device is fully implanted and consists of a breathing sensor lead and a stimulation lead, powered by a small battery.  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 502-583-3687 or go to

Other Alternatives to CPAP Therapy

  • 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.
