Introduction: Pulse oximetry is a non invasive method which determines the saturation of hemoglobin in oxygen and is early detecting  hypoxic episodes. The aim of the present study was to evaluate nurses' knowledge working in Intensive Care Unit (ICU)  regarding  pulse oximetry.  Method and material: The sample of the study consisted of 206 ICU nurses  in 5 general hospitals in Attica. Data was collected using a specially designed questionnaire for the purpose of research, which included demographic and other variables as well as  21 questions assessing nurses' knowledge regarding pulse oximetry, in type true/false. For data analysis was used the statistical program SPSS v.19 and the statistical methods Mann-Whitney, Kruskal-Willis and Kolmogorov-Smirnov. Results: From 206 participants 66.5% were women, 47.1% were married 43,2% worked in intensive Care Unit  from 1 to 5 years. The average age of the sample was 34,5 ± 6,346 years.  The average nurses' knowledge score regarding pulse oximetry was 62,80±10,19, in a range from 52.61 to 72.99. The factor that statistically differentiated the mean score (p=0,011) was  the educational level, as the nurses having a university degree responded more appropriately to evaluation questions based on empirical basis. Conclusion: The level of nurses' knowledge working in I.C.U regarding pulse oximetry was valued as distinguished but was based primarily on empirical basis. It was also found a higher percentage of correct answers among nurses having a university degree.  Implementation of educational programs will promote the level of knowledge and the theoretical principles regarding  pulse oximetry.
