Sleep Laboratory and CPAP Program

About the Program
The Audie L. Murphy VA Sleep Disorders Center provides full service diagnostic sleep testing for veterans. The Sleep Laboratory includes 6 testing beds and performs diagnostic polysomnograms, CPAP, BiPAP, and ASV titration studies, as well as daytime testing such as multiple sleep latency tests (MSLT) and maintenance of wakefulness tests (MWT).
Patients referred to the sleep laboratory for testing have a variety of disorders including sleep disordered breathing, such as obstructive sleep apnea, central apnea, and hypoventilation syndromes. Many other sleep disorders such as a narcolepsy, sleep related movement disorders, parasomnias, and sleep stage disorders are also commonly identified during testing. The Sleep Laboratory follows the accreditation standards of the American Academy of Sleep Medicine and is committed to conducting the highest quality testing possible.
Sleep Medicine is a multidisciplinary specialty and the Audie L. Murphy VA Medical Center is fortunate to have a broad range of clinicians who provide ongoing care to patients with sleep disorders, including Board Certified Sleep Specialists, Pulmonologists, Neurologists, Psychiatrists, Psychologists, Otolaryngologists, and Dentists. For patients with obstructive sleep apnea and other sleep related breathing disorders, ongoing care and treatment with CPAP, BiPAP, or ASV is provided through the Sleep Medicine Department in the CPAP Clinic.

Commonly Asked Questions

1) Does the VA provide So clean or other PAP therapy device cleaners?
    At this time, the VA does not provide device cleaners.  We recommend that you use the current recommended strategies for cleaning as outlined during your visit

2) Does the VA provide TRAVEL CPAPs?

3) What alternatives  are there to PAP therapy?
    PAP therapy is the Gold-Standard for the treatment of OSA and studies have shown that the below listed therapies are not as successful as PAP Therapy. Our service will first attempt to help you use PAP therapy for your sleep apnea.
    Referrals for alternate therapies will only be submitted if the following eligibility criteria are met: 

TAP device (also known as mandibular repositioning device or dental device)
Must have a certain number of your own teeth
Must have mild or moderate OSA or have a special circumstance
 • To be eligible for the VA to provide the device, you currently must be 100% Service Connected or otherwise eligible for VA Dental care
 Inspire
 • Patient ineligible when BMI is >32 because the device does not work as well when patients are overweight.  There are other indications and contraindications that must be met and should be discussed with your referring provider.
 Surgery – there are potential surgical options if you are unable to use PAP therapy.  ENT asks that all referrals for surgery for Sleep Apnea be referred by the Sleep Medicine Specialist.
    In many cases, patients will continue to need CPAP therapy as well.
