First, patients see a sleep specialist to develop a detailed sleep and medical history. Patients may be candidates for Home Sleep Testing (HST) or in-clinic testing. (See information below on HST.) When it is time for the in-clinic sleep study, patients stay overnight in the CSI sleep center’s comfortable and supportive environment where their sleep is monitored and measured closely by highly trained specialists using state-of-the-art technology. Patients receive an initial review after their study and their full results within two-to-three days. CSI medical staff work closely with patients’ physicians and other healthcare providers, reporting test result information as appropriate, with permission and in a timely fashion.
