Do I Need a Sleep Study?

Sleep studies exist because sleep apnea — and many other sleep disorders — cannot be reliably diagnosed from symptoms alone. Symptoms like fatigue and snoring have multiple potential causes, and the only way to determine whether obstructive sleep apnea is present is to objectively measure what is happening during sleep.

A sleep study provides the clinical data required to confirm a diagnosis, determine severity, and guide the selection of appropriate treatment. Without a physician-interpreted sleep study, neither CPAP nor oral appliance therapy can be prescribed for sleep apnea.

A sleep study measures the number and type of breathing events per hour (apnea-hypopnea index or AHI), blood oxygen saturation trends, breathing effort, heart rate patterns, and sleep position. Together these data points allow a physician to determine whether obstructive sleep apnea is present and classify it as mild (AHI 5–14), moderate (AHI 15–29), or severe (AHI 30+).

This classification directly informs treatment selection. Patients with mild to moderate sleep apnea and those with CPAP intolerance at any severity are typically excellent candidates for oral appliance therapy through a dental sleep medicine provider like Houston Sleep Associates.

The first step is taking the Sleep Apnea Assessment to gauge your risk level, or scheduling a consultation directly with Houston Sleep Associates. Our team can help coordinate home sleep testing and guide you through the diagnostic process from start to finish.
