Home sleep testing has become the preferred testing for a number of reasons including convenience, comfort and affordability. Due to significant advancements in the technology of CPAP machines, CPAP therapy can be initiated without a formal in-lab CPAP titration. Data from newer CPAP machines can be reviewed and evaluated for correct pressure settings, required to prevent breathing obstructions. The newer machines are called Auto CPAP devices which adjust automatically throughout the night depending on the individual respiratory needs of the patient.
Home sleep testing is less disruptive to the patient by allowing the testing to be done in the convenience of their home. Most insurances cover the cost of this test. Home sleep testing is a fraction of the cost of in-lab sleep tests.
In home sleep testing is available through the use of a portable computer monitoring device that measures heart rate, oxygen saturation and analyzes breathing patterns throughout the night. Home sleep testing is generally done over two consecutive nights. The computer monitor is attached to a belt worn around the chest. Included with the monitor is a pulse oximeter worn on the finger and a nasal cannula placed in the nose. When the testing in completed, the unit is returned to the office and data is downloaded into a report which is interpreted by the board-certified sleep physician.
A Neurological Wellness technician will explain how to use the home sleep testing device (shown above).
A small home sleep testing computer is attached to a belt which goes around the chest. It monitors chest movements during breathing, pulse oximetry and heart rate.
