Polysomnography (Sleep Studies), and Home sleep testing
The Lung Center offers state of the art Polysomnography (Sleep Testing) to identify multitude of sleep disorders. We also offer home-based sleep testing services If you are unable to come into our center.
Whether referred by your primary care physician, or if your self-referred, call us to address any of your sleep/wake concerns to set up a consultation with our experienced team. Afterwards we will be able to decide if additional diagnostic testing is necessary. The final result of our practices is better sleep and better health.
One of the most common sleep disorders is sleep apnea. This is a sleep disturbance that happens when you wake up coughing or feeling a loss of breath. Another disorder we treat is when you are awake, but do not feel rested
We diagnose these issues and once identified, we set you up with whatever sleep testing you might need. After the final testing is carried out, we refer you if you need a CPAP and then do a follow-up.
Sleep studies or Polysomnograms are tests that record what happens to your body during sleep. The studies are done to find out what is causing your sleep problems.
Sleep studies can also determine whether you have a problem with your stages of sleep. The two main types of sleep are non–rapid eye movement (NREM) and rapid eye movement (REM). Normally, NREM and REM alternate 4 to 5 times during a night's sleep. A change in this cycle may make it hard for you to sleep soundly.
Sleep testing is non-invasive which means no needles are involved, nothing goes under your skin. Common sleep studies are:
- Polysomnogram. This test records several body functions during sleep, including brain activity, eye movement, oxygen and carbon dioxide blood levels, heart rate and rhythm, breathing rate and rhythm, the flow of air through your mouth and nose, snoring, body muscle movements, and chest and belly movement.
- Multiple sleep latency test (MSLT). This test measures how long it takes you to fall asleep. It also determines whether you enter REM sleep.
- Maintenance of wakefulness test (MWT). This test measures whether you can stay awake during a time when you are normally awake. During a Polysomnogram
- Sticky patches with sensors called electrodes are placed on your scalp, face, chest, limbs, and a finger. While you sleep, these sensors record your brain activity, eye movements, heart rate and rhythm, blood pressure, and the amount of oxygen in your blood.
- Elastic belts are placed around your chest and belly. They measure chest movements and the strength and duration of inhaled and exhaled breaths.
- Wires attached to the sensors transmit the data to a computer in the next room. The wires are very thin and flexible. They are bundled together so they don't restrict movement, disrupt your sleep, or cause other discomfort. There are over 90 sleep/wake disorders identified by the International Classification of Sleep Disorders. Below is a list of some of the more common and well know disorders.
- Sleep Apnea
- REM Behavior Disorder
- Sleep Phase Disorders
- Periodic Limb Movements in Sleep
- Restless Legs Syndrome (RLS) and Sleep
- Sleep walking (somnambulism)
- Sleep or night terrors
