Overnight Sleep Study

Spirometry
Spirometry is a tool used to evaluate how well air is moving into and out of the lungs. When performing this procedure the individual being tested exhales as hard and fast as they can and then inhales rapidly. By evaluating information gathered during this test, we can determine certain characteristics about air flowing into and out of the lungs. The person being tested is then compared to a "normal" group. This normal group is simply a selected group of people of the same age, height, race and sex, who do not have lung disease to use for comparison.

when you have most of your dreams. The breathing monitors show the number of times you stop breathing or when you have limited airflow coming from your nose or mouth. A clip will also be placed on your finger to note changes in the level of oxygen in your blood. The leg sensors show both minor twitches and major movements that occur during the night.


Who gets a sleep study?
A sleep study (polysomnogram) is often used in the following cases:


  • when diagnosing sleep related breathing disorders such as sleep apnea
  • to set the correct level/s of positive airway pressure (PAP) for patients diagnosed with sleep related  breathing disorders
  • as a pre-screening test performed in conjunction with a multiple sleep latency test (MSLT) to see if someone may have narcolepsy or excessive daytime sleepiness
  • to look for certain parasomnias, (sleep related behaviors), some of which may be violent in nature, which could cause harm to both the patient and the bed partner 


You may also have a repeat sleep study if you are already being treated for a sleep disorder but you are not feeling better. This study can help Dr. Jain see why the treatment may not be working.  

What happens when I get a sleep study?
You will be asked to come to the center in the evening around 8:30 PM. Upon your arrival, you will be greeted by one of our technicians who will escort you to one of our private “hotel quality” bedrooms. You will then be given time to relax and have the testing process explained to you.  
Shortly after, the technician will then start placing sensors on your head, face and legs. These sensors are connected to a unit that will then send signals to a computer for evaluation while you are sleeping.
You will not feel any discomfort during the sleep study. Our staff will make every effort to help you maintain the same sleep patterns to which you adhere at home, while acquiring the data during the study.

Once the lights are turned out and the testing begins, a low-light video camera is used to view your sleep positions, and other occurrences that may take place while you are asleep. The wires are long enough to let you move around and turn over in bed, but there are several instances where the 
technician may have to enter your room during your study, such as the wires becoming tangled, a sensor coming loose, or to detach you from the system if you need to go to the bathroom. 
Nearly everyone falls asleep during the study. Most people do not sleep as well as they do at home. 
This will not affect the results. In most cases, you do not need to sleep for a full eight hours to find the 

source of your problem.

In the morning, once the study has been completed we will remove all the sensors, and you will be free to go. Despite possibly feeling a little tired, you may return to your normal daily activities including going back to work. 

Maintenance of Wakefulness Tests (MWT)
The Maintenance of Wakefulness Test (MWT) is a test that helps determine a person's level of alertness. It is often used to determine if a patient's treatment for a sleep disorder is effective. The test normally follows a nocturnal sleep study. Testing starts at 8:00 a.m. and consists of four 40-minute trials that are conducted every two hours until the testing has been completed. You will be sitting in a darkened room and you are encouraged to stay awake during the trials and between each study. You will be asked to remain awake throughout the day.

Pulmonary Function Testing
This type of testing may be ordered by Dr. Jain for patients suspected of having underlying problems with Asthma or COPD to see how their lungs are functioning. The testing may consist of one or several test procedures. These tests require special equipment, trained technologists to perform the tests, and 
a qualified professional such as Dr. Jain who is also a Board Certified Pulmonologist to interpret the results. The various parts of a pulmonary function test are explained next:

Physician Consultation

Within the medical community, sleep medicine is considered a highly specialized field. At Westmoreland Sleep Medicine, our 

patients meet personally with Dr. Jain who will perform a comprehensive evaluation to determine how we can best meet a patient's needs. In addition to the initial consultation, a followup visit will be necessary to discuss the outcomes of any testing that was required to verify and diagnose any sleep issues. During that visit Dr. Jain will set up a scheduled follow-up program for you, or he can continue to meet with you as needed, to ensure that your sleep disorder is resolved.

Services Offered

From the information gathered with this test we make certain deductions about what is happening throughout the lung. We focus specifically on OBSTRUCTIVE LUNG DISEASE (COPD) and it's level of  severity with this testing.

Obstructive lung disease simply put, is a problem within the airways that does not allow airflow to move smoothly from the alveoli (air sacs of the lungs) and smallest airways out through your trachea (main windpipe) and ultimately out through your mouth when you exhale or inhale. There are a number of
common and uncommon processes that can lead to this kind of a problem. Some of the more common include emphysema, asthma and chronic bronchitis.


Bronchodilator Testing with Spirometry
This test is performed when an obstruction is identified by the initial spirometry. A bronchodilator is a medication which will help open up airways which have bronchoconstriction (the airway is partially closed off). The goal of this test is to identify how much if any of a patient's obstructive disease can be
reversed. This information is used both for clarifying the diagnosis, and to help determine the correct medications for treatment.

Body Plethysmography - Lung Volume Assessment
Another tool used to assess lung function is body plethysmography. With this tool, the volumes of the lung are evaluated. Although the lung would appear to have only two obvious volumes, empty and full, there are actually four different volumes and four combinations of volumes known 
as capacities that are used to assess the lung. Body plethysmography is the most accurate means available at this time to assess lung volumes.

Diffusing Capacity (DLCO)
This test is used to evaluate how well oxygen moves into and out of the lungs. Certain diseases will lead to difficulties in getting oxygen from in the alveoli (air sac in the lung) into the blood where it is carried to the rest of the body. Identifying problems with this process in the lung can identify people at risk for needing oxygen. With this additional information, the pulmonary function test interpretation is also greatly improved.

What is a sleep study? (Polysomnogram)

While sleeping, your brain waves, heartbeat, and breathingpatterns are monitored and recorded by small sensors. These sensors are strategically placed on your head, face, chest and legs. Several of the sensors are used specifically to determine when you are asleep, awake, or the stage of sleep you may be experiencing. Others detect brain wave patterns and eye movements verifying when you are in rapid eye movement (REM) sleep. This is a stage of sleep where your eyes twitch and your brain waves are very active. It is also the stage of sleep

Who reads the study?
A technologist is the first one to look over the data and score the sleep study. They will initially chart your sleep stages, then, they will look for any events of abnormal breathing or leg movement. The results will then be read by Dr. Jain, who will review all of the data  gathered during your sleep study.

Multiple Sleep Latency Testing (MSLT)

The Multiple Sleep Latency Test (MSLT) consists of a series of 4-5 short nap periods during which your brain waves are monitored to determine if you fall asleep, and if you do fall asleep, do you enter into REM sleep. The test normally follows a nocturnal sleep study. The first nap period will start at
approximately 7:00 AM with the rest of the naps occurring every two hours until the testing has been completed. You will be asked to remain awake between the nap periods. The staff at Westmoreland Sleep Medicine will go out of their way to make you feel relaxed and comfortable during your stay.
