Computer Analysis Of Tracheal Sounds in Sleep (CATSIS)

We will develop CATSIS a simple, safe, and unobtrusive test that will screen patients in their homes for disordered breathing during sleep. The CATSIS system uses simple hardware to record a patient's tracheal breath sounds during sleep. These recordings are then analyzed by specially-developed software running on a mainstream personal computer with the aim of quantifying the occurrence of apnea. Like any screening test, the CATSIS results would then be factored into a decision about whether or not to perform the expensive 'gold standard' test, in this case, an overnight polysomnography in a sleep laboratory.
