08. Comparison of Oxygen Saturation Measured by Pulse Oximetry and Arterial Blood Gas Analysis in Neonates

RfPid changes in arterial blood gas values are
common in critically ill patients.! Arterial
blood gas is usually beneficial to discern the
ature of gas exchange disturbances, the
effectiveness of compensation, Z,3 and is required for
adequate management. 4 Blood gas provides
information on oxygenation, carbon dioxide
homeostasis, and acid-base balance, and therefore is
the most important tool utilized in evaluating the
adequacy of pulmonary function.5 Although arterial
partial pressure of oxygen (PaOz) is the standard
measurement of blood oxygenation, the oxygen
saturation measured by pulse oximetry (SapOz) is now
a customary noninvasive assessment of blood
oxygenation in newborn infants.6 Pulse oximetry is a
noninvasive and reliable method to detect
hypoxemia.! Using pulse oximetry, oxygen saturation
can easily be monitored continuously at the bedside.3
Comparison of oxygen saturation by pulse oximetry
and arterial blood gas analysis has been reported by
several authors. 7-9 They found different values
between SaOz and SapOz'..........
