4. Medicare Guidelines Beneficiaries may self-administer home based overnight oximetry tests under the direction of a Medicare-enrolled Independent Diagnostic Testing Facility (IDTF) under the following circumstances: 1. The beneficiary’s treating physician has contacted the IDTF to order an overnight pulse oximetry test before the test is performed. 2. The test is performed under the direction and/or instruction of a Medicare- approved IDTF. The IDTF must provide clear written instructions to the beneficiary including 24 hour technical support. The DME supplier may not create this written instruction, provide verbal instructions, answer questions from the beneficiary. 3. The test unit is sealed and tamper-proof such that test results cannot be accessed by anyone other than the IDTF who is responsible for transmitting a test report to the treating physician. In no cases may the DME supplier access or manipulate the test results in any form. The IDTF must send the test results to the physician. The IDTF may send the test results to the supplier if the beneficiary has signed a release permitting the supplier to receive the report.

6. Why are these oximeters still using the same technology from 2000? 20002012 Nonin 2500 Palm Sat / Respironics 920MP Nonin 2500 Palm Sat / Respironics 920MP Nonin 8500 Palm Sat / Respironics 920M Nonin 8500 Palm Sat / Respironics 920M

7. Market Physicians Inherent problems with the 920M / 920M Plus NO Data to Upload When the batteries are removed or die the memory gets erased automatically. Bad Date / Time When the batteries are replaced in between patients the date and time reset back to the default 1/1/2004. Patients wear device long enough When you pick up device you have no way of knowing if there’s sufficient data on the device to get a successful upload. When the above occur, your center must re-test the pt. This upsets the MD and Patient!

8. Market Physicians All VirtuOx Oximeters come with Good Study Indicators or (GSI) a new technology that will 100% eliminate all failed uploads that normally would need retesting.. Product Key Features: Good Study Indicator will tell pt how many hours, minutes and seconds they used the previous night unlike the 920m/920mplus Memory / time / date store in between battery removal unlike 920m/920mplus Measures SPO2 / HR in High Resolution Pulse Oximetry which is the GOLD standard in sleep labs unlike the 920m/920mplus More comfortable uses Silicone Rubber Boot probes unlike the 920m/920mplus

9. Market Physicians Studies show the 920m/920mplus can failed to be uploaded 5-37% of the time! Why not guarantee a successful upload 100% of the time!
