A sleep test, also known as a polysomnography or PSG, evaluates how well a person sleeps at night and checks for any sleep issues. During a sleep test, technicians attach sensors to the patient to monitor biometric data like heart rate, breathing patterns, brain waves, oxygen levels, and eye and leg movements throughout the night. The results help doctors diagnose sleep disorders.

Types of Sleep Testing Services
There are different types of sleep tests that can be used depending on the suspected sleep issue:

Overnight Polysomnography in a Lab
The standard test is an overnight PSG in a sleep lab. Multiple sensors are attached to the patient and they sleep in the lab overnight while technicians monitor them. This test best evaluates sleep architecture and any disruptions. It can diagnose sleep issues like sleep apnea, insomnia, narcolepsy, and restless legs syndrome.

Home Sleep Testing Services
For less severe cases, a home sleep test may be recommended. Small portable monitors are used to track oxygen levels, heart rate, respiratory effort, and sometimes snoring levels. While more limited than a lab test, home tests can adequately diagnose sleep apnea in many cases.

Maintenance of Wakefulness Test
This test evaluates how well a patient can stay awake at scheduled times during the day. Sleep Testing Services is used to diagnose excessive daytime sleepiness and help differentiate narcolepsy from other fatigue issues. The patient must resist falling asleep during multiple trial periods in a monitored setting.

Multiple Sleep Latency Test
Like the MWT, this test measures daytime sleepiness but examines how quickly a person falls asleep rather than how long they can stay awake. Naps are scheduled two hours apart and the time to onset of sleep is recorded. Shorter latencies indicate higher sleepiness levels.

Things to Expect during a Sleep Testing Service

Preparation and Setup
Patients are advised not to drink caffeinated beverages or use electronics before bed. Setup typically takes 90 minutes with 25-35 sensors attached to monitor bodily functions. Patients are allowed to go about their normal pre-bed routine to get comfortable.

Overnight Stay
Patients sleep in a private, dark, soundproof room set up like a bedroom. There are no restrictions on position or comfort during sleep. Technicians remotely monitor all readings from an adjacent room. Bathroom access is available without disconnecting sensors.

Analysis and Report
The next day, a sleep specialist analyzes all the night's recordings and scores different sleep stages, events, and abnormalities. A full report is generated detailing things like total sleep time, wake after sleep onset, apnea-hypopnea index, leg movements, and more.

Understanding the Results
The medical report indicates if any sleep disorders were detected or explains normal, healthy sleep patterns. Abnormal findings help diagnose issues like obstructive sleep apnea, insomnia, restless legs syndrome, etc. Treatment options are then discussed based on the test results and patient symptoms.

Benefits of Sleep Testing
A sleep study provides an objective medical evaluation of a person's sleep quality and architecture. It can diagnose underlying sleep disorders not evident from symptoms alone. Knowing the specific issue helps target the most effective therapies instead of guessing treatments. Regular testing also tracks progress with things like CPAP compliance and response to medication or lifestyle changes. Overall, sleep testing helps properly diagnose and manage sleep problems.
