467 The Oygen Tissue Saturation (SPO2) Audit

Abstract

Background and aims: Pulse oximetry (SpO2) is a fundamental aspect of PIC (Paediatric Intensive Care) (Hanning and Alexander-Williams, 1995). Due to widespread use of pulse oximetry, competence and thus understanding of the basic principles related to this monitoring is vital. Clinical audit was performed to ascertain nursing knowledge related to the use of pulse oximetry.Method: A questionnaire was given out to nurses (n=40) at a PIC unit. The questionnaire contained four questions regarding the use of pulse oximetry. The results were counted using nominal data and content analysis was used to ascertain themes.Results: Less than half of those who participated felt that pulse oximetry was indicated in children who had respiratory distress (45%), respiratory failure (10%) or those who were requiring supplemental oxygen therapy (40%).80% of participants could explain how pulse oximetry works. Common themes from content analysis were infrared light versus light meeting a sensor through the periphery and detecting the amount of oxygen bound to haemoglobin. 20% could not explain how pulse oximetry worked.Disadvantages highlighted were burns related to use (35%) and inaccuracy on movement (55%).Rotation of probe sites (82%) was listed as the most common nursing consideration when using pulse oximetry. Pressure sore and burn prevention, was also found to be paramount.Conclusion: Results suggest that further education regarding the use of pulse oximetry is needed. Education regarding the indications for the use of this monitoring is required. Further, more indepth investigation is required.
