Overview of Limited Channel Test / Home Sleep Study

The  use of a Home Sleep Study is for diagnosing obstructive sleep apnea (OSA).  The OCST  is often required as the initial screening tool by certain insurance companies today. Although home sleep testing works fairly well for the diagnosis of moderate to severe obstructive sleep apnea, the OCST  has a high false negative rate.  Cases of mild obstructive sleep apnea are often missed with this method of testing and a in lab polysomnogram will be necessary is there is significant suspicion of sleep apnea.   For the home sleep test you will be given a device to take home and monitor your sleep.  One of the staff will instruct you in proper use of the device in our office before you take it home.  You will sleep with the device for one or two nights and you will return the monitor the next day for our review and analysis.  In home sleep testing, your breathing and nasal airflow is monitored as well as your heart rate and oxygen levels.

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.

Home Sleep Study Follow Up

A sleep professional will review and analyze the breathing patterns and problems of the patient and follow up will be done to determine a treatment plan.
