Abstract
Pulse oximetry is a non-invasive technique of measuring oxygenation of the blood that is used worldwide to assess the respiratory status in critically ill patients.
The ability to detect the different absorption spectra oxygenated and deoxygenated hemoglobin allows pulse oximeters to measure the amount of oxygen-saturated hemoglobin in the capillaries of an extremity.
THe aim of our study was determination the most appropriate site for pulse oximetry probe placement in newborns and children, by evaluating simultaneous SpO2 levels recorded by pulse oximetry from probes placed on ear, thumb and big toe of pediatric patients and to compare the validity of the results with arterial blood gas (ABG) analysis.
The sample of our study included 150 pediatric patients: 31 were newborn infants (aged 30 days) and 119 were children (aged 45.76 ± 40.54 months) , who were admitted to the pediatric intensive care unit (PICU) or neonatal intensive care unit, Assiut University Childern Hospital during a 6 month period from 1 July 2012 to 31 December 2012 .
In our study we found that the ear probe is more reliable in the measurement of oxygen saturation than was the finger probe and toe probe. Our study showed that Spο2 at the ear had the highest clinical agreement with Saο2 in both neonates and children.
