Positive Airway Pressure (PAP) Therapy for Sleep Apnea

Years of Experience With Breathing Machines for Sleep Apnea

The Norton Sleep Center is a leader in providing positive airway pressure (PAP) therapy — breathing machines — for sleep apnea patients from Louisville and Southern Indiana.

PAP therapy via a mask you wear while you sleep is the most common treatment for sleep apnea. The breathing machine gently blows air through a small mask or less-intrusive nasal pillows that don’t cover your mouth.

Obstructive sleep apnea is a condition that causes the upper airway to collapse while you sleep. This prevents air from reaching your lungs. Providing positive air pressure through one of a variety of masks keeps the airway open.

Your board-certified and fellowship-trained physician will likely prescribe one of the following types of PAP therapy machines:

  • Continuous positive airway pressure (CPAP) is the most common device. This machine maintains the same level of air pressure whether you are exhaling or inhaling. You may wear a CPAP for part of the night at your diagnostic polysomnography to fine-tune the machine. Sometimes we’ll have to bring you back for a follow-up sleep study to adjust the machine for you.
  • Bi-level positive airway pressure (BiPAP) provides greater pressure while you’re inhaling than exhaling. This is an alternative for patients who have difficulty with conventional CPAP machines. BiPAP may also require fine tuning.
  • Auto-adjusting PAP devices — AutoPAP — automatically vary the pressure to the lowest level your body needs to keep airways open. After a month or so, we will examine data from the machine and set a regular pressure level without need for another sleep study. AutoPAP devices can be more expensive than conventional CPAP or BiPAP machines.

Does Insurance Cover the Cost of a Sleep Apnea Machine?

Virtually every insurance plan provides some coverage for AutoPAP, BiPAP or CPAP. The questions for your insurer include how much is the copay and how long will you have to pay regular copays before the insurer pays to purchase the machine.

At Norton Sleep Center, we have extensive experience with insurance questions surrounding PAP therapy and can help you navigate the complexities.
