Obstructive Sleep Apnea

Obstructive Sleep Apnea (OSA) is a prevalent health hazard with serious health consequences. These include excessive daytime sleepiness, depression, cognitive disturbances, cardiovascular disease, cerebrovascular disease, and hypertension. People with OSA have almost three times more risk of developing Type II Diabetes.

Obstructive Sleep Apnea is a frequent partial or complete collapse of the airway during sleep. The muscles in the chest relax, making the airway more susceptible to collapse during inspiration. With the airway blocked breathing ceases (apnea), oxygen levels drop, heart rate may increase or decrease, and blood pressure increases. In order to breathe again, you briefly awaken, and sleep is non-restful.


Symptoms of Obstructive Sleep Apnea

  • Excessive daytime sleepiness
  • Loud snoring
  • Increased night time urination
  • Observed apnea events
  • Choking or gasping while sleeping
  • Feeling sleepy while driving
  • Feeling sleepy while reading
  • Morning headaches
  • Dry mouth upon awakening
  • Excessive sweating at night
  • History of high blood pressure
  • History of stroke
  • History of heart attack
  • History of heart arrhythmia
  • Tiredness upon awakening


Polysomnography (Sleep Study)

If you have evidence of Obstructive Sleep Apnea you may be scheduled for an overnight sleep study (polysomnogram). The study consists monitoring of multiple parameters, including continuous overnight oximetry, electrocardiography (EKG), electroencephalography (EEG), electromyelography (EMG), oculography, a flow sensor, and a snoring detector. We also monitor your chest and abdominal movements.

Once you arrive at our center, you will be directed to one of our comfortable rooms, designed to make you feel as if you were at home. You will then have multiple sensors placed on your head and body in order to effectively monitor your sleep. The information obtained from the sleep study allows an accurate diagnosis.
