Ninety-two patients with clinically suspected obstructive sleep apnoea syndrome (OSAS) were assessed using overnight polysomnography. The patients were classified as follows: 14 patients were non-apnoeic snorers 27 patients had mild OSAS 31 patients had moderate OSAS and 20 patients had severe OSAS. Minimum SaO(2) level mean SaO(2) time below 85% of SaO(2) the ratio between the time SaO(2) and total sleep time and body mass index (BMI) were assessed retrospectively. There was a statistically significant difference between the non-apnoeic group and OSAS patients in Min SaO(2) (P = 0.03). Patients who had Min SaO(2) above 85% could be evaluated as non-apnoeic snorershowever SaO(2) and BMI were not found to be useful in the assessment of the severity of OSAS.eninfo:eu-repo/semantics/openAccessObstructive sleepApnoea syndromePolysomnographyOxygen saturationDiagnosisArticle344346527WOS:00017860850001210.1046/j.1365-2273.2002.00592.x2-s2.0-0036413230N/AN/A12383294
