DIAGNOSE YOUR HEALTH

At the Insomnia and Sleep Institute of Arizona, you will receive a consultative evaluation during your first visit with us, which includes a comprehensive review of health and symptoms, such as questionnaires and sleep diaries, to properly diagnose your disorder. From there, a treatment will be recommended to help you gain control and get a better night’s rest.

If further information is needed to provide a proper diagnosis, a sleep study may be required. Using polysomnograhy, the sleep specialist will monitor and measure brain activity, eye activity, heart activity, muscles contractions, chest and abdominal movements, breathing, oxygen levels, and sleeping position. The specialist will monitor you overnight in the sleep center and will analyze compiled information upon completion.

 

Once your sleep condition has been determined, the specialist will then make a treatment recommendation. Many sleep disorders require only behavioral strategies. Other conditions require additional methods, such as medical devices or medication. For example, individuals with sleep apnea may need CPAP therapy or an oral appliance.

 

The sleep specialists at The Insomnia and Sleep Institute of Arizona have years of experience successfully treating hundreds of patients with a wide variety of sleep disorders and will find an effective solution for you. Say goodbye to sleepless nights by making an appointment with us today.

 

LCT (LIMITED CHANNEL TEST/HOME SLEEP STUDY)
Overview Of Limited Channel Test / Home Sleep Study

The only use of a Home Sleep Study is for diagnosing obstructive sleep apnea (OSA) but carries a high false negative rate and often is required as the initial screening tool by certain insurance companies today. A patient is given a device to take home and monitor their sleep, which they return the next day for review and analysis. Breathing and airflow is monitored through heart rate and oxygen levels throughout the night.

Preparation For Limited Channel Test / Home Sleep Study

A home sleep study is designed only for screening for obstructive sleep apnea (OSA) only as the sensitivity of a home sleep study is far less than that of the in laboratory sleep study (PSG). An initial meeting with a sleep specialist to determine who is eligible is required. Once a patient has met the requirements, they are given a device to take home and use during sleep to monitor breathing. As breathing is the only area being monitored, less sensors are required, hence the convenience to a home study.

Limited Channel / Home Sleep Study Testing

A sleep specialist instructs patients on how to use the devices and return the next day for results. All the patient must to do is set up the devices properly, sleep as usual and return the next day with the equipment for review.

Limited Channel Test / Home Sleep Study Follow Up

A sleep professional will review and analyze the breathing patterns and problems of the patient and determine a treatment plan.

 

MATRIX IN-LAB ORAL APPLIANCE TITRATION
Overview Of MATRx In-Lab Oral Appliance Titration

Obstructive sleep apnea (OSA) is a serious disorder in which a person experiences breathing interference during sleep. Tissue collapsing in the back of the throat or the tongue blocking the airway limits the amount of air to the lungs. The brain and body can become oxygen deprived and cause a panicked and breathless attack anywhere from a couple to a few hundred times a night. To treat this severe sleep disorder, patients are fitted with a MATRx device. This device is fitted orally and used to predict a patient’s target sleep position for optimal airway flow and breathing efficiency.

Preparation For MATRx In-Lab Oral Appliance Titration

To fit the MATRx device, a sleep specialist must define the patient’s mandibular range of motion using three significant measurements. These dimensions are determined using impression trays that are trimmed and unique for every patient. This information is calculated to define each patient’s distinctive bite position, maximum protrusion and full retrusion of the mandible.

MATRx In-Lab Oral Appliance Titration Testing

Once the patient is fitted with the device and their distinctive mandibular range of motion is determined, treatment can begin in a polysomnographic sleep study (PSG). The patient’s measurements are put into the system software for patient safety. A sleep technologist remotely controls and advances the mandible to increase breathing efficiency and oxygen intake during sleep. The ultimate goal of the device and PSG is to find and implement the patient’s optimal protrusive position and effectively treat OSA.

MATRx In-Lab Oral Appliance Titration Follow Up

The patient’s target protrusive position should then be determined for an effective OSA treatment. Regular follow ups may be necessary if OSA continues.

 

MWT (MAINTENANCE OF WAKEFULNESS TEST)
Overview Of Maintenance Of Wakefulness Testing

The Maintenance of Wakefulness Test (MWT) is a sleep study used to measure and patient’s ability to stay awake. Multiple times throughout the day, the patient is asked to try and sleep. Electrodes and monitors track and record body function as the patient sleeps in an incremented pattern throughout the day.

 

Preparation For Maintenance Of Wakefulness Testing

Like Multiple Sleep Latency Test (MSLT), Polysomnography (PSG) is typically required the night before an MWT. This ensures more accurate results. In this case, testing would begin the night before with a monitored, continuous sleep followed by shorter, periodic naps.

Maintenance Of Wakefulness Testing

Following the PSG, the patient is set up with monitoring devices and asked to try and sleep four separate times, about two hours apart.

Maintenance Of Wakefulness Testing Follow Up

All the information recorded regarding body function of the brain, eyes, heart, muscles, etc. is reviewed and analyzed by a sleep specialist.

ACTIGRAPHY
Overview Of Actigraphy

Actigraphy is a sleep monitoring technique that uses a device called an actimetry sensor to monitor motor activity during sleep. The unit records and saves patient’s movements and patterns. The most common actigraphy device is similar to wrist watch size and is usually worn for multiple days and nights to determine a patient’s sleep patterns, light intensity, movement, naps, etc. The information is then reviewed for analysis.

Preparation For Actigraphy

 

Actigraphy has only minimal affects on regular sleep patterns and is relatively simple, patients of all ages can generally sleep out of lab and receive accurate results. An initial consultation with a sleep professional and further instruction of the device is all that is needed to begin actigraphy.

 

OVERNIGHT POLYSOMNOGRAPHY (PSG)
Overview Of Overnight Polysomnography

The most common test in diagnosing obstructive sleep apnea (OSA) is Polysomnography (PSG). Using electrodes, PSG monitors brain function, eye movement, muscle activity, heart rhythm, respiratory airflow and other body functions involved in sleep patterns. Usually one night of sleep is adequate to receive sufficient information for a diagnosis.

Preparation For Overnight Polysomnography

An initial meeting with a sleep professional to determine the main areas of concern and past medical history is important. If a seizure disorder is suspected, more electrodes will be added in specific areas to also detect seizure activity. Other unique medical histories are determined so each PSG can be most effective to each individual patient. Because the test is overnight in a lab, patient’s generally come in early evening and are introduced to the process and prepared with EEG, EOG, EMG, EKG and respiratory and heart monitors.

Overnight Polysomnography Testing

During overnight PSG testing, the patient is wired with a minimum of 12 channels with 22 wires that are attached to a single system for recording, displaying and saving the results. After the patient is set up and falls asleep, a sleep technician observes through a video monitor.

Overnight Polysomnography Testing Follow Up

The electrodes and monitors gather data that is analyzed by a scorer. The reviews are studied in 30 second epochs, or ‘wavelengths’ of data produced by the EEG electrodes. The areas studied include sleep latency, efficiency, stages, breathing regularities, arousals of brain activity, heart rhythm, leg movement, body position and oxygen levels. The sleep professional reviewing these results looks for abnormalities and oddities that may be causing sleep problems. A treatment plan will be created based on PSG results to increase patient sleep health.

 

CPAP TITRATION
Overview Of CPAP Titration

CPAP titration is a method of study used to record and analyze continuous positive airway pressure. This study is recommended when a patient suffers from sleep breathing disorders such as obstructive sleep apnea (OSA), hypoventilation and hypoxemia. A pressurized mask is placed over the nose, mouth or both and regulated throughout the night to increase airflow. A sleep technician monitors the patient as they sleep overnight in a lab.

Preparation For CPAP Titration

The CPAP titration is an in-lab, overnight study. The patient comes in early evening and is set up and introduced before the sleep study begins. Prior to coming into the lab, a patient should follow their normal routine throughout the day, not consume caffeine after lunch time and not nap.

CPAP Titration Testing

CPAP titration is similar to PSG testing in the way it is executed. The patient is fitted with a mask and other sensors to monitor body functions. A sleep technician monitors the patient and brain, heart, respiratory and motor activity is recorded for later analysis.

CPAP Titration Follow Up

A sleep physician will review the results of the CPAP titration study and move forward with a treatment as necessary. Often the patient will be instructed to use a home CPAP mask for nightly home use.

 

MSLT (MULTIPLE SLEEP LATENCY TEST)
Overview Of Multiple Sleep Latency Testing

The Multiple Sleep Latency Test (MSLT) is a method of sleep study that identifies the causes of excessive sleepiness. Polysomnography (PSG) testing is required the night prior to the MSLT. Following the PSG, the patient is asked to take several periodic naps throughout the day. The patient is monitored with sensors to record body function patterns and activity.

Preparation For Multiple Sleep Latency Testing

A PSG must precede a MSLT for accurate results. The following day, the patient will be monitored and instructed regarding naps throughout the day.

Multiple Sleep Latency Testing

A Multiple Sleep Latency Test is very similar to PSG in the way it is carried out and studying. Some differences may occur regarding electrode amount and location. MSLT focuses more on short patterns and ability to come in and out of sleep rather than a full night, continuous study.

Multiple Sleep Latency Testing Follow Up

All the results recorded from the electrodes and measuring devices will be scored and analyzed by a professional sleep technician. The results will be reviewed and an individual diagnosis and treatment plan will be developed and discussed.
