Coordinated care

What to expect: Our specialists will listen to your story and evaluate you for a sleep disorder.

If you have a disorder, they will work with you to decide the best treatment. Your plan will most likely include:

  • A consultation to evaluate your sleep concerns.
  • An at-home sleep study or an overnight sleep study in one of our comfortable sleep labs, in Portland and in Hillsboro.
  • Home medical equipment if you have sleep apnea.

The latest technology

Home testing: Our home sleep tests can measure moderate to severe sleep apnea. Smartphone apps, bedside monitors and wearable items such as bracelets and smart watches can collect and analyze data about your sleep patterns.
