Spaulding Sleep Center

The Spaulding Sleep Center uses the latest technology to diagnose and treat sleep disorders, with a focus on patients with cardiac and/or pulmonary disease.


Treating a Broad Range of Sleep Disorders

Many doctors affiliated with Massachusetts General Hospital refer patients with suspected sleep disorders to the Spaulding Sleep Center.

Directed by Mass General pulmonologist and sleep medicine specialist James Mojica, MD, the Sleep Center evaluates and treats patients with a broad range of respiratory and neurologic sleep disorders, including:

  • Sleep-disordered breathing (e.g. obstructive sleep apnea, central sleep apnea)
  • Hypoventilation syndromes (e.g. alveolar- or obesity-related, or central hypoventilation syndromes)
  • Circadian disorders (i.e. disruptions to the body's circadian clock)
  • Movement disorders (e.g. periodic leg movement disorder)
  • Parasomnias (e.g. sleepwalking, sleep-talking)
  • Hypersomnias (e.g. narcolepsy or other forms of central hypersomnia)
  • Insomnia

A Veteran Staff & Sophisticated Technology

Dr. Mojica leads a veteran staff that includes a chief technologist and five sleep technicians, each of whom has worked in the field for at least 15 years.

All of the center's sleep technicians are respiratory therapists, which makes them well equipped to address breathing problems that might occur overnight. Their experience helps them put patients at ease and ensure high-quality test results.

The Sleep Center's labs feature state-of-the-art technology that enables superior diagnostic testing. By gathering very precise details about breathing, movements and behaviors during sleep, we can detect even mild forms of sleep disorders.

What to Expect

Once you have secured a referral, please call the Sleep Center at 617-952-6871 to book your study.

Upon arriving at the Sleep Center on the evening of your evaluation, you will meet with one of our sleep technicians. He or she will discuss your medical history, preview what will happen overnight and answer any questions you may have.

During the night, your sleep technician will carefully monitor your sleep patterns and may treat you with positive airway pressure (PAP) therapy or oxygen therapy. You can expect to leave by 7 a.m. the next morning after showering and dressing.

Following your stay, a technician will score your recorded data. Dr. Mojica will interpret this information, send test and evaluation results to your doctor and formulate an individualized treatment plan based on your medical history and particular sleep disorder. Where applicable, Dr. Mojica may recommend referrals to other specialists (e.g. ear, nose and throat surgeons or sleep dentists) for further evaluation.
