OBSTRUCTIVE SLEEP APNEA
UNDERSTANDING OBSTRUCTIVE SLEEP APNEA, SNORING, SYMPTOMS & TREATMENTS
WHAT IS OBSTRUCTIVE SLEEP APNEA (OSA)?
Welcome to our practice. We are committed to helping patients improve their sleep, breathing, and overall health through accurate diagnosis and treatment of snoring and obstructive sleep apnea (OSA).
Obstructive Sleep Apnea occurs when the airway becomes partially or completely blocked during sleep, causing breathing to slow down or stop temporarily. These pauses in breathing are called “apneas” and may lower oxygen levels and disrupt sleep quality.
WHAT ARE SYMPTOMS OF OSA?
Common symptoms of OSA include:
-
Loud snoring
-
Gasping or choking during sleep
-
Pauses in breathing
-
Poor or restless sleep
-
Daytime fatigue or sleepiness
-
Morning headaches
Often, a bed partner or family member notices these symptoms first.
In adults, more than 5 breathing interruptions per hour may indicate sleep apnea. In children, more than 1 episode per hour may be considered abnormal. Children with OSA may also experience hyperactivity, difficulty concentrating, or ADHD-like symptoms.
Please take time to read more about OSA, potential costs, and what our practice does every day to diagnose and treat patients with Obstructive Sleep Apnea.

Sleep Apnea Evaluation & Treatment Guide
What Is Obstructive Sleep Apnea (OSA)?
Obstructive Sleep Apnea occurs when breathing repeatedly stops or becomes partially blocked during sleep due to obstruction in the nose or throat area. Patients may experience:
-
Loud snoring
-
Choking or gasping during sleep
-
Pauses in breathing
-
Poor-quality sleep
-
Daytime fatigue or sleepiness
OSA can range from mild to severe. Determining the severity is important because untreated moderate to severe sleep apnea has been associated with significant long-term health risks. The goal of our practice is to ensure that our patients are getting sufficient oxygen during the day and night. Each recommendation that we make is to improve your nasal airways to help you be healthy and improve your quality of life.
Why Sleep Testing Is Important
Studies spanning more than 30 years have shown that untreated moderate to severe OSA may increase the risk of:
-
High blood pressure
-
Heart disease
-
Stroke
-
Heart attacks
-
Diabetes
-
Dementia
-
Daytime fatigue and poor concentration
-
Motor vehicle and workplace accidents
The at-home sleep study administered by our office measures airway resistance, oxygen saturation, brain activity, and the number of times a person stops breathing per hour. The combination of these results determines whether a patient has:
-
Primary snoring only
-
Mild OSA
-
Moderate OSA
-
Severe OSA
The health risks associated with mild OSA are generally much lower than those associated with moderate or severe disease.
Our Sleep Study Protocol
Our standard recommendation is to perform 2–3 nights of home sleep testing whenever possible. We recommend multiple nights because many patients experience moderate night-to-night variation in their breathing patterns, and additional data helps us more accurately assess risk and severity.
Insurance Coverage
Insurance coverage for home sleep studies varies by plan. Our staff will verify authorization requirements and potential costs based on your specific insurance plan.
Common scenarios include:
-
Some insurance plans approve 2–3 nights of testing
-
Some plans approve only 1 night
-
Additional nights not covered by insurance may become the patient’s responsibility
Potential Out-of-Pocket Costs
Costs vary widely depending on insurance coverage, deductible status, and equipment provider. Typical estimates may include:
-
Home sleep study (covered by insurance): Often subject to deductible, copay, or coinsurance
-
Additional self-pay home sleep study night: Approximately $150–$300 per night
-
CPAP/AutoPAP device: Often covered partially by insurance after deductible requirements
-
CPAP supplies (mask, tubing, filters, cushions): Usually replaced every 3–6 months and may involve copays or coinsurance
We strongly encourage patients to contact their insurance carrier directly to verify:
-
Sleep study coverage
-
Deductible and coinsurance amounts
-
CPAP coverage requirements
-
Compliance requirements for ongoing supply coverage
-
