Introduction: Continues monitoring of oxygen saturation by pulse oximetery is known as a routine technique in critical care of patients. But previous researches showed some differences in its measurement according to probe placement.
Materials and Methods: In this cross sectional analytical study 36 admitted neonates below one months age were selected. Sampling method was convenience and sample size was estimated according to α=5% and β=20% .Samples oxygen saturation was measured three times by hand and foot pulse oximetery and direct method. Data was analyzed using paired t test.
Results: Analysis of results showed significantly dofference between both two pulse oximetery methods with arterial blood gas. Comparison of oximetery methods with direct one showed more accuracy of foot probe (p<0/05).
Conclusion: We concluded that pulse oximetery do not reliably predict changes in saO2 and also probe placement causes some differences in oximetery results.
