Sleep Study Process
Overnight Sleep Study This study allows you to measure how well your patient sleeps and how much, and assess breathing and other physiological functions such as EKG. It’s also referred to as an all-night polysomnogram. If your patient is having seizures, extended EEG monitoring using a more extensive group of electrodes on their scalp along with video monitoring can help to differentiate these two similar disorders. However, you need to meet certain criteria during the diagnostic portion of the patient’s in-lab sleep study in order to start CPAP therapy on the same night. Maintenance of Wakefulness Testing MWT During this test, you’ll have the patient stay awake and sit in bed for four, minute sessions every two hours over the day. This study is sometimes done on workers in the transportation industry to evaluate if the patient can fly or drive safely.

Additional marks made in the back of the head are similar to the marks made for F7 and F8. In the back of the head, these are the locations for T5 and T6. This gives the first mark for P3.

A titration study is a type of polysomnography that is performed when a patient has been previously diagnosed with sleep apnea either with an in-center or in-home sleep study and is used to determine the optimal CPAP settings which eliminate all or most apnea events.
This test is often ordered when sleep apnea is highly likely and can eliminate the need for a second night sleep study if the titration is successfully completed. Start and end times for most overnight sleep studies Most sleep studies start in the evening.

But persistent questions about their reliability, and the consequent refusal of most insurers to pay for them, have kept them out of the mainstream of practice. In March, the Centers for Medicare and Medicaid Services, whose reimbursement rules are generally adopted by private insurers, dropped its long-standing opposition to home studies. According to the National Coverage Determination that was released that month, a diagnosis of obstructive sleep apnea can be made—and CPAP therapy covered—on the basis of a clinical evaluation coupled with a home study using a device that measures, at a minimum, airflow, heart rate, and oxygen saturation.
A positive diagnosis is established if: The apnea-hypopnea index as measured by the portable device is 15 or more 15 apneas or hypopneas an hour or the AHI is between 5 and 14 and the patient has documented symptoms of excessive daytime sleepiness, impaired cognition, mood disorders, hypertension, ischemic heart disease, or history of stroke. The NCD specifies that the home study must be ordered and supervised by the treating physician.
It also limits the initial coverage of CPAP to a week trial period. Previous to its decision, the CMS had considered and rejected home studies on four occasions.
