A sleep study (polysomnography) is the gold standard test for diagnosing sleep disorders. If your sleep doctor suspects you have a sleep disorder, a sleep study provides the objective data needed for accurate diagnosis.
Types of Sleep Studies We Offer
- In-lab polysomnography (PSG) — comprehensive overnight monitoring in a sleep lab
- Home sleep apnea testing (HSAT) — portable device you use at home
- Split-night study — diagnosis and CPAP titration in one night
- CPAP titration study — determines your optimal CPAP pressure
- MSLT (Multiple Sleep Latency Test) — evaluates for narcolepsy
What a Sleep Study Measures
During an in-lab sleep study, we monitor:
- Brain waves (EEG) — sleep stages and quality
- Eye movements (EOG) — REM sleep detection
- Muscle activity (EMG) — limb movements
- Heart rhythm (ECG)
- Breathing effort and airflow
- Blood oxygen levels (SpO2)
- Body position and snoring
Who Needs a Sleep Study?
A sleep study may be recommended if you experience:
- Loud snoring with witnessed breathing pauses
- Excessive daytime sleepiness despite adequate sleep time
- Suspected sleep apnea
- Unusual behaviors during sleep (sleepwalking, acting out dreams)
- Suspected narcolepsy
