Types of Sleep Studies

NPSG (Nocturnal Polysomnogram)

During the test, various sensors are attached to your body in order to record essential information while you sleep, such as brain waves, breathing, heart activity, leg movements and oxygen levels. The sensors usually do not affect your sleep and can easily be removed if you need to get up during the night. 

In most cases, the sleep study begins around 10:30 p.m. and continues until you are awakened between 5 and 6 a.m. However, daytime sleep studies are available for those who work nights. A sleep technologist will monitor you throughout the study. 

CPAP (Continuous Positive Airway Pressure)

Continuous positive airway pressure (CPAP) machines are a standard treatment for obstructive sleep apnea. The equipment used in CPAP therapy has three main parts:

  • An air pump;
  • A mask to cover the nose, and often the mouth as well; and,
  • A tube that links the air pump and the mask.

CPAP increases pressure in the lungs and holds open collapsed alveoli, pushes more oxygen across the alveolar membrane, and forces interstitial fluid back into the pulmonary vasculature. This improves oxygenation, ventilation and easer of breathing.

Split Night

A split night sleep test is done when severe Obstructive Sleep Apnea is found during the first few hours of the sleep test. When it is clear that severe apnea is present, treatment with continuous positive airway pressure (CPAP) will be started halfway through the night of the test. Thus, the first half of the night is used to establish the diagnosis of obstructive sleep apnea while the second half is used to determine how much pressure will be needed to treat the apnea.

Sleep is a vital ingredient needed for the body and mind to function. Most of our lives will be spent in slumber, recharging our batteries for the day ahead. Regardless of the cause, interrupted or poor quality of sleep can be extremely problematic. The brain which functions as the "battery" of your body, needs adequate sleep to be able to perform its many functions correctly.

  • Have you been told you snore loud enough to be heard through a closed door?
  • How often do you feel tired or fatigued after your sleep?
  • Do you know if you stop breathing, or has anyone witnessed you stop breathing while asleep?
  • Do you have high blood pressure or are you on medication for high blood pressure?
  • Have you ever nodded off or fallen asleep while driving a vehicle?

If you answered "Yes" to two or more questions, you may have a sleep disorder. Please consult with your physician and schedule an appointment with us.


Sleep Apnea

Sleep Apnea is a sleep disorder that occurs when a person’s breathing is interrupted during sleep. The pauses can last from a few seconds to minutes and can occur more than five times per hour, to as high as 100 times per hour. (Fewer than five times per hour is normal). Sometimes when you start breathing again, you make a loud snort or choking sound.

The chronic sleep deprivation caused by sleep apnea can result in daytime sleepiness, slow reflexes, poor concentration, and an increased risk of accidents. Sleep apnea can cause moodiness, irritability, and even lead to depression, as well as serious physical health problems such as diabetes, heart disease, liver problems, and weight gain. With the right treatment and self-help strategies, however, you can control your snoring and the symptoms of sleep apnea, get your sleep back on track, and feel refreshed and alert during the day.

Often the first signs of OSA are recognized not by the patient, but by the bed partner. Many of those affected have no sleep complaints. The most common signs and symptoms of OSA include:

  • Snoring;
  • Daytime sleepiness or fatigue;
  • Restlessness during sleep, frequent nighttime awakenings;
  • Sudden awakenings with a sensation of gasping or choking;
  • Dry mouth or sore throat upon awakening;
  • Cognitive impairment, such as trouble concentrating, forgetfulness, or irritability;
  • Mood disturbances (depression or anxiety);
  • Night sweats;
  • Sexual dysfunction; and,
  • Headaches.


Insomnia is commonly referred to as a difficulty initiating or maintaining sleep or as a non-refreshing sleep. The most common signs and symptoms of Insomnia include:

  • Difficulty falling asleep at night;
  • Waking during the night;
  • Waking earlier than desired;
  • Still feeling tired after a night's sleep;
  • Daytime fatigue or sleepiness;
  • Irritability, depression, or anxiety;
  • Poor concentration and focus;
  • Being uncoordinated, an increase in errors or accidents;
  • Tension headaches (feels like a tight band around head);
  • Difficulty socializing;
  • Gastrointestinal symptoms; and,
  • Worrying about sleeping.


Narcolepsy is exemplified by excessive daytime sleepiness, and may cause a person to fall asleep at inappropriate times or have sudden loss of muscle control.
