Sleep Disorders Center
The Sleep Disorders Center staff at Pella Regional helps diagnose and treat sleep problems that affect so many people. A sleep study may be the first step toward answers that can help with daytime tiredness and other health concerns that go along with poor sleeping.
Sleep Study, Polysomnogram
A sleep study, or polysomnogram, is a recording that includes measurements used to identify various sleep problems. The sleep study takes up to 16 different measurements in the brain or body the entire time the patient sleeps. These measurements include EEG (brain waves), eye movement, muscle activity, electrocardiogram (heart), leg movement, breathing, oxygen level in blood and more.
The sleep study, its analysis and its interpretation are part of a complex process. Sleep studies contain more than 800 pages of data. After the patient's night in the sleep lab, a sleep technologist will analyze the data. This involves isolating irregularities in sleep patterns or breathing. Often the sleep technologist is determining if the patient stopped breathing and, if so, counting how many times.
Below is a sample recording from a sleep study:
Home Sleep Testing
Home sleep testing is for individuals who have suspected sleep apnea, but no other health concerns. Pella Regional’s sleep physician evaluates and determines who is a candidate for this type of testing.
Home sleep testing can screen for sleep apnea from the comforts of the patient’s home with equipment that is very easy to operate. After the test is completed, the staff downloads the recorded results and our board certified sleep physician reviews the data.
A summary report is prepared outlining the data and sent to one of our physicians specializing in sleep medicine. The sleep specialist interprets the information and determines the severity of the patient's condition.
Patients have a follow-up visit with their health care provider or a sleep specialist to discuss the results of the study. To fully understand the results of the sleep study, their implications, and treatment options, patients should meet face-to-face with a health care professional.
