| ABSTRACT |
Study objective
To determine the accuracy of the pulse oximetry in the emergency department.
Study design : Prospective, cross ―sectional, paired measurement of SpO2 against SaO2.
Setting
University affiliated hospital.
Interventions : A pulse oximeter with digital probe was used to measure SpO2. Arterial blood gas was drawn at the same time to measure SaO2.
Results:
There were no significant difference between SpO2 and SaO2. when SpO2 was
above or less than 90% (mean≥90%= 0.598 土2.665,mean<90%=2.926土7.807≥90%=0. 0796, p<90%=0.0860), but all together there were significant difference(mean = 1. 22 土 4.70 ; p=0.017).
Conclusion
The pulse oximetry is potentially useful in patients with clinical signs of acute hypoxemia and patients receiving interventions that may produce acute hypoxemia, and is a must device in emergency department.
