In-Lab or At Home Diagnostics

We offer both in-lab sleep studies and at-home sleep tests. The test of choice is determined based on sleep symptoms, underlying medical comorbidities, age, and insurance criteria.
HomeLab

Home Sleep Test

A home sleep test is used for the evaluation of suspected sleep apnea only, and is done with a small device that records airflow, breathing pattern, heart rate, breathing effort and oxygenation. If a home sleep test is suggestive of sleep apnea, treatment can be initiated based on home sleep test results. If the home sleep test has inadequate data, or does not reveal sleep apnea diagnosis, an in-lab polysomnogram is required for further evaluation.

We use very small and convenient ResMed ApneaLink Air and CleveMed SleepView home sleep testing devices at our sleep lab.

Diagnostic Polysomnogram (In-lab Sleep Study)

Diagnostic polysomnogram is the gold standard test used for the evaluation of suspected sleep apnea, REM behavior disorder (dream enactment), and periodic limb movement disorder.

Overnight diagnostic polysomnogram is done in the sleep lab and conducted by experienced sleep technicians. Multiple electrodes are placed to monitor brain waves (EEG), eye movements, muscle activity, heart rate, heart rhythm, leg movements, and other sleep parameters.

Titration Study

Titration study is used to determine the effective treatment pressure from CPAP or BiPAP for the treatment of sleep apnea. We use nasal pillows, nasal masks or full-face mask during titration study, and the pressure setting from CPAP or BiPAP is gradually adjusted by the sleep technician based on airflow recording in monitored setting in the sleep lab. Multiple electrodes are also placed to monitor brain waves (EEG), eye movements, muscle activity, heart rate, heart rhythm, leg movements, and other sleep parameters. We also conduct titration studies using oral appliance to determine effective setting on the oral appliance to treat sleep apnea effectively.

Multiple Sleep Latency Test (MSLT)

This study is performed for the evaluation of excessive daytime sleepiness if there is a strong clinical suspicion for narcolepsy or idiopathic hypersomnia. MSLT is done on the day after an overnight polysomnogram. After the polysomnogram, the patient is given an opportunity to nap for 15-20 minutes. During this time, brain activity is monitored to find out how quickly you are falling asleep and how quickly you are going into REM sleep.

CPAP/BiPAP & ACCESSORIES

We provide medical equipment from reputed brands such as Resmed, Fisher & Paykel, and Philips Respironics.
