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.
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.
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.
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.
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.
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.
Sleep Profiler™ EEG Sleep Monitor Is A New Tool Employed By The Insomnia And Sleep Institute Of Arizona In Allowing For Performing In-Home EEG Over Several Nights To Allow For Sleep Staging And Architecture To Better Allow For Evaluation Of Sleep Patterns While The Patients Sleep At Home. This Tool Allows The Physician To Be Able To Analyze One's Sleep Patterns Using EEG Monitoring To Better Assess Patients Presenting With Complaints Of Insomnia. It Providers A More Object Measure Of A Person's True Sleep At Home Rather Than The Use Of Traditional Sleep Tracking Tools Currently Available On The Market.
