Sleep studies, in a friendly community setting

Getting enough sleep is key to your health. Some sleep issues can affect your heart and blood pressure if not treated. That’s where we can help.

Sleep testing is available for adults 18 and older using state-of-the-art equipment and techniques. Our team of doctors, respiratory therapists and technologists will find out what’s causing your sleep problems and design a plan to help you sleep better. Together, we’ll help you get a good night’s sleep.

Your Care at its Best

About Sleep Tests

A sleep test is an overnight study to understand your body while you sleep - at our Sleep Lab or, in some cases, at home. During the test, we monitor your breathing, oxygen level, heart rate, movements, snoring and brain activity. 

After seeing test results, you will get follow-up visits and a treatment plan to help you sleep better. This may include:

  • Changes to your sleep habits
  • Behavioral techniques and cognitive behavioral therapy
  • Medication management
  • PAP (positive airway pressure) therapy

About PAP Therapy

If you have trouble wearing a PAP mask for obstructive sleep apnea, we can help. We hold “mask clinics” three times a month to help choose the right mask for your face and help you with mask fittings.

A Team of Sleep Experts

The CHA Sleep Medicine team includes board-certified physicians who help diagnose and manage sleep problems. These include obstructive sleep apnea, insomnia, restless leg syndrome and other conditions that keep you from getting the rest you need.

CHA has been doing sleep studies for more than thirty years. Our experienced staff is deeply committed to the local community and welcomes all patients, including those whose first language is not English. We provide interpreter services for all languages.
