SLEEP SERVICES

Valley Sleep Center provides sleep studies in Arizona

Valley Sleep Center Sleep testing suites offer a homelike atmosphere and include a private bathroom, Cable Television, Wireless internet, and most rooms offer a motorized bed for convenience/comfort.

The treatment and testing equipment utilized in the sleep center exceeds American Academy of Sleep Medicine recommendations to provide patients with top tier sleep recordings for analysis by our Sleep Physicians.

All Valley Sleep Centers are Accredited by the American Academy of Sleep Medicine and are staffed primarily by Board Certified Sleep Physicians and Registered Polysomnographic Technologists.

Valley Sleep Center offers a wide range of options for sleep testing as well as Treatment options like Inspire Therapy, Continuous Positive Airway Pressure (CPAP), Mandibular Advancement Devices (Dental Appliances), and other Technologies as they are available.

 

Listed below are the current Testing Options available at Valley Sleep Centers

Adult Polysomnography

An adult Polysomnography (PSG) is a gold standard sleep test that uses: small electrodes on the head to monitor brain waves to determine sleep, eye movements, and chin activity; flexible Velcro belts are placed over the stomach and chest to monitor breathing;  a small nasal cannula and thermal sensor will be placed by the nose to monitor airflow;  electrodes will be placed on the legs to monitor limb movements and placed near the heart to record the heartbeat signal; a pulse oximeter will be placed on your finger to monitor heart rate and Oxygen level; a snore microphone will be placed on the neck to monitor any snores.

This study is performed without the initiation of Positive Airway Pressure (PAP) therapy during the night.  This study may include analysis of Inspire Therapy, Mandibular Advancement Therapy, and other non-PAP Treatments.

Pediatric Polysomnography

An Pediatric Polysomnography (PSG) is a gold standard sleep test that uses: small electrodes on the head to monitor brain waves to determine sleep, eye movements, and chin activity; flexible Velcro belts are placed over the stomach and chest to monitor breathing;  a small nasal cannula and thermal sensor will be placed by the nose to monitor airflow;  electrodes will be placed on the legs to monitor limb movements and placed near the heart to record the heartbeat signal; a pulse oximeter will be placed on your finger to monitor heart rate and Oxygen level; a snore microphone will be placed on the neck to monitor any snores.

EtCO2 monitoring is generally performed on Pediatric Polysomnography Tests. This study is performed without the initiation of Positive Airway Pressure (PAP) therapy during the night

.

Split Polysomnography

An Split Polysomnography (PSG) is a gold standard sleep test that uses: small electrodes on the head to monitor brain waves to determine sleep, eye movements, and chin activity; flexible Velcro belts are placed over the stomach and chest to monitor breathing;  a small nasal cannula and thermal sensor will be placed by the nose to monitor airflow;  electrodes will be placed on the legs to monitor limb movements and placed near the heart to record the heartbeat signal; a pulse oximeter will be placed on your finger to monitor heart rate and Oxygen level; a snore microphone will be placed on the neck to monitor any snores.

This Study Type is unique in that it monitors the patient in the first half of the night (Baseline) and then allows for the initiation of Positive Airway Pressure (PAP) to be initiated and Titrated in the second half of the night to treat Sleep Apnea. Most sleep testing is ordered as a Split Night Polysomnography.

Titration Polysomnography

A titration polysomnography (PSG) is the gold standard study performed to determine the necessary Positive Airway Pressure (PAP) required to alleviate apnea and/or snoring. This study monitors the same body functions as the Adult/Pediatric PSG while the patient is using Positive Airway Pressure (PAP) Therapy all night during testing.

This test is ordered once a patient has already qualified for PAP therapy and needs additional time to obtain an optimal Titration or has a re-occurrence of symptoms and needs adjustments made to the PAP therapy levels during monitored sleep.

Multiple Sleep Latency Testing

Multiple Sleep Latency Testing (MSLT) is the gold standard daytime nap study that measures the ability of a person to fall asleep. This study must be performed in conjunction with a PSG/Titration Study the night before. This test is used assess how quickly a person is able to fall asleep during periods during the day after a typical night of sleep.  A typical MSLT consists of 5 Nap opportunities spaced 2 hours apart and requires a full day to complete. Evaluation for Narcolepsy and Hypersomnia’s are reasons this test may be ordered. Drug Screening is part of this test.

Maintenance of Wakefulness Testing

The Maintenance of Wakefulness Test (MWT) is the gold standard test used to measures the ability of a person to stay awake.  The Patient is hooked up with electrodes like the Adult Polysomnogram to determine how awake the person remains during each trial period. The typical MWT requires a patient to stay awake during four 40-minute trials while seated in a bed with the back and head supported by a bolster pillow for comfort. During testing, the room is dark and quiet except for a 7.5-W nightlight used as a light source and patients are instructed to avoid extreme behaviors to stay awake.   This test is typically ordered on Pilots, Drivers, or any patient treated for a Sleep Disorder needing to document they can remain awake even during the toughest circumstances.  Drug Screening is part of this test.

This test is used to monitor a patient’s oxygen levels and heart rate at night. This test may be ordered to assess current oxygen use in the home or to evaluate the need for oxygen at night.

 

Home Sleep Testing

Home Sleep Apnea Testing (HSAT) is used to determine if a patient with a high probability of Obstructive Sleep Apnea based on examination and questionnaires does in fact have Sleep Apnea.  The HSAT device is a limited channel device that monitors Breathing effort, Airflow, Heart rate, Snoring, and Oxygen levels and more channels depending on the device. The HSAT provides enough data to look for sleep apnea, however does not usually provide enough data to monitor sleep type and duration, arousals, limb or body movements, body sleep positions, your Heart Beat signal pattern, and other parameters available in the Polysomnogram.

The Home Sleep Apnea Test if very effective and looking for the typical snoring and breathing pauses seen with Sleep Apnea and is less expensive and convenient as it is performed in the patient’s home.

An in-lab test may be required for patients with other Sleep Disorders or those who have Heart, Respiratory, and/or Neurological medical conditions.

ApneaLink is used to monitor a patient’s oxygen levels and heart rate during the night. An ApneaLink is similar to a nocturnal oximetry; however, the ApneaLink provides doctors with additional screening signs that indicate the possibility of sleep apnea at night.
