Sleep Tests
Approximately 50 - 70 million Americans are reportedly affected by Sleep Deprivation. When a patient feels that they have some sleep problems or sleeping disorders they may consult a doctor or specialist for diagnosis. To confirm an initial diagnosis the patient may be referred to a sleep clinic for a sleep test.

A sleeping test is therefore used as a diagnostic tool in sleep medicine. A Polysomnography (PSG) is the most common multi-parametric test used in the study of sleep.

Sleep Tests
Sleep studies or tests are conducted to confirm and gain additional information about a patient's sleep problems. A sleep test might be used for any of the following conditions:

Sleep apnea
Obstructive Sleep Apnea
Insomnia
Narcolepsy
Periodic limb movement disorder (PLMD)
Excessive daytime sleepiness (EDS)
Hypersomnia
REM sleeping disorder
Excessive snoring
Heart rhythm problems
Shift work sleeping disorder
Circadian rhythm problems

Sleep Test Types
The different types of sleeping disorders and a varity of sleeping test equipment to help with the diagnosis and subsequent treatment. Descriptions of these sleeping test types are detailed below.

Sleep Test Types - Polysomnogram (PSG)
A Polysomnogram (PSG) sleep test is a recording of sleep usually performed in a sleep center. A Polysomnogram sleeping test involves linking a patient up to recording sensors that monitor breathing, heart rate, movement, brainwaves, etc. The most common sleeping test for diagnosing sleeping disorders. A Polysomnogram might be used to confirm or detect any of the following conditions:

Obstructive Sleep Apnea
Insomnia
Narcolepsy
Periodic limb movement disorder (PLMD)
Excessive daytime sleepiness (EDS)
Hypersomnia
REM sleeping disorder

A polysomnogram sleeping study will typically record a minimum of 11 channels requiring a minimum of 22 wire attachments to the patient.

Sleep Test Types - Maintenance of Wakefulness Test (MWT)
A Maintenance of Wakefulness Test (MWT) is used to prove whether a person can stay awake during the day. This sleeping test is usually conducted on people that have a job where vigilance is requires eg. truck drivers

Sleep Test Types - Multiple sleep latency test (MSLT)
A Multiple sleep latency test (MSLT) sleep test to monitor a series of four or five naps during the day after a nocturnal polysomnogram. The MSLT is used to help diagnose Narcolepsy and other disorders of excessive daytime sleepiness.

Sleep Treatment Device - CPAP
CPAP is an acronym for Continuous Positive Airway Pressure. A CPAP is a  device used to treat moderate to severe sleep apnea.

The machine sends air at a constant, continuous pressure to help keep a person's airway open, allowing the patient to breathe normally. This is a machine that creates a pneumatic split of a personís airway. A CPAP is generally interfaced with the patient by way of a nasal breathing mask; this mask is worn during sleep and delivers pressurized air to keep the patientís airway from collapsing as a result of Sleep Apnea.  A CPAP mask covering the nose and mouth, helps when patients on CPAP are mouth breathing.
