What is a System One bi-level therapy device? Bi-level therapy devices are set to deliver two levels of pressure during the night—a lower pressure when you breathe out (exhalation) and a higher level of pressure when you breathe in (inhalation). These devices are sometimes prescribed for patients who have trouble tolerating one constant pressure from a CPAP device. Most are equipped with various features that can help make therapy more comfortable.
