Abstract

The aim of this study was to examine the role of oxygen saturation (SaO(2)) measurement in identifying apnoeic snorers from non-apnoeic snorers and in the assessment of the severity of obstructive sleep apnoea. 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 snorers
however SaO(2) and BMI were not found to be useful in the assessment of the severity of OSAS.
