    UnlabelledThere is little information on oxygen saturation (SaO2) values in children in developing countries.AimTo determine the reference values for oxygen saturation by pulse oximetry in healthy children living at sea level in Chennai and aged between 1 mth and 5 yrs.Design And SettingA prospective study was conducted in Kanchi Kamakoti CHILDS Trust Hospital from February to May 2005.MethodsA total of 626 healthy children aged between 1 mth and 5 yrs were examined for heart rate, respiratory rate and SaO2.ResultsThe mean SaO2 levels for children in the age groups 1-3 mths, 3 mths to 1 yr, 1-3 years and 3-5 years were 98.5%, 98.8%, 98.9% and 99.1%, respectively. The overall mean and median SaO(2) values for the children in the different age groups were 99%. The mean -2 SD values of oxygen saturation in the age groups were 96.5%, 96.4%, 96.3% and 97.1%, respectively, with an overall mean of 96.6%.ConclusionThe reference value for mean SaO2 in healthy children aged between 1 mth and 5 yrs and living at sea level in Chennai city was 98.5% or more, but the -2SD values had a mean of 96.6%.
