The patient has to go through a pre-procedure evaluation including consultation with ENT to ascertain any local pathology. The Sleep Study is performed in two stages- the first stage is diagnostic which involves confirmation of Obstructive Sleep Apnoea (OSA) in the patient. Subsequent to confirmation of OSA in patient, the second stageis planned wherein titration is performed with CPAP / BiPAP. This helps in identifying whether patient will be benefitted with CPAP / BiPAP and what pressure setting is required to get optimum results. Detailed report of the sleep study is furnished after 24 hours of sleep study.
