Diagnosing Obstructive Sleep Apnea requires more than just identifying symptoms; it involves a formal medical test. At Dental Sleep Medicine of Charlotte, under Dr. Sudikoff’s expert guidance, we help our patients in Charlotte, NC, get the data needed for a definitive diagnosis, often through the convenience and comfort of a home sleep test. Dr. Sudikoff’s extensive experience allows her to interpret your test results with precision, ensuring you receive an accurate diagnosis and an effective treatment plan.
How At-Home Sleep Testing Works
We can provide you with a small, user-friendly device to be used in the comfort of your own bed. This device, such as the WatchPAT® ONE, is worn like a wristwatch. It includes a finger probe and chest sensor to gather crucial data while you sleep, including:
● Peripheral Arterial Tone (PAT): A physiological signal that decreases during sleep apnea events.
● Oxygen Saturation: The amount of oxygen in your blood.
● Heart Rate: Your heart’s rhythm and beats per minute.
● Actigraphy: Measures your sleep and wake cycles, providing an accurate total sleep time.
The data is then instantly uploaded to the cloud for our team to interpret. This allows us to calculate your AHI (Apnea-Hypopnea Index) and determine the severity of your condition without the need for an overnight stay in a lab.
Common FAQs About Sleep Testing
Why choose an at-home test over an in-lab sleep study?
Home sleep tests are generally more convenient, comfortable, and affordable. They provide a realistic view of your sleep patterns in your natural environment. For most patients, they provide sufficient data to accurately diagnose OSA.
What is AHI and why is it important?
AHI stands for Apnea-Hypopnea Index. It is the key metric used to diagnose and classify the severity of sleep apnea. It measures the average number of apnea (complete pauses in breathing) and hypopnea (partial pauses) events you have per hour of sleep. AHI is used to classify sleep apnea as mild, moderate, or severe.
What if my home sleep test results are inconclusive?
While home sleep tests are highly accurate for diagnosing OSA, some cases may require more detailed information. If your results are inconclusive, or if we suspect another sleep disorder, we may recommend a formal in-lab sleep study (polysomnography) for a more comprehensive analysis.
