Polymesam (PM) recordings was performed in 320 patients admitted to Sleep Laboratory with suspicion of OSA. OSA was diagnosed in 179 of them (55.9%), group (PM-Ch). These patients were obese (BMI--34.3 +/- 6.7 kg/m2) and had moderately-severe OSA (RDI--41.5 +/- 19.9 and ODI--43.7 +/- 21.5). They suffered from excessive daytime sleepiness (ESS = 12.2 +/- 5.5). PM was negative in 141 person (44.1%), (PM-Z). Subjects PM-Z had significantly lower BMI and rarely suffered from excessive daytime sleepiness. In 38 subjects PM-Z a full PSG was performed. In 12 PSG confirmed OSA (AHI--31.6 +/- 19.9). Both studies (PM and PSG) were negative in 26 subjects. In 10 obese subjects PM-Ch full PSG confirmed diagnosis.
Conclusions:
PM recording can replace full PSG in majority of patients suspected of OSA. Patients with typical symptoms of OSA and negative PM require PSG.
