Obstructive Sleep Apnea Testing Pasadena Texas

Sleep Apnea Testing

Obstructive Sleep Apnea treatment includes a consultation with Dr. Nugent, a thorough sleep history review, physical exam and and a sleep test. This is the first step in screening for Obstructive Sleep Apnea. Then to get a diagnosis of sleep apnea you will need to take a sleep test called a polysomnogram. Dr. Nugent arranges to have the medical equipment sent to your house. You wear the device for two nights of sleep and simply put the equipment back in the pre-paid box. The data collected is studied by a Board-Certified Sleep Physician who writes a report and gives a diagnosis.

The home sleep test is easy to use and you are sleeping in your own bed. There are also sleep labs where you sleep in a strange bed with a plethora of wires attached to your body while a sleep technician watches you sleep.

You can have a home sleep test (HST) or go to a sleep lab, the choice is your.

Terminology of the Sleep Test:

An apnea event = a cessation of ventilation(breathing) for 10 seconds or longer.

Hypopnea = occurs when there is a partial obstruction somewhere in the airflow. It involves a decrease in oxygen levels in the blood (oxygen desaturation-uptake of greater than 4%).

RDI (Respiratory Disturbance Index ) / AHI (Apnea-Hypopnea Index) = average number of apneas plus hypopneas combined per hour of sleep.

UARS – Upper Airway Resistance Syndrome = this condition lies midway between benign snoring and true Obstructive Sleep Apnea. People with UARS suffer many of the symptoms of Obstructive Sleep Apnea but sleep testing results lack evidence demonstrating true apneas or oxygen desaturation.
