Home sleep testing with no equipment to buy.
Many home sleep test devices are losing service. Neurovirtual replaces them with a flow-based device and the software to run it, in one price per study.

No capital. One price per study.
Instead of buying recorders, you pay one fee for each completed study. The HST Compass, consumables, replacement units and software are all included.

Scoring you can see. Not a black box.
