Comparative Study
[Noninvasive determination of oxygen saturation using pulse oximetry in pediatric cardiology].
Pulse oximetry is a relatively new noninvasive method to measure arterial oxygen saturation (SO2). We evaluated the reliability of a pulse oximeter (N-100, Nellcor/Drger, Lübeck) in single and continuous measurements of SO2. During cardiac catheterisation we compared pulse oximeter (puls. ⋯ Continuous measurements with the pulse oximeter are very simple and very reliable and are not associated with skin injury. Because the pulse oximeters responses rapid to oxygenation changes and does not need calibration it is very valuable in the assessment of therapeutic procedures in patients with cyanotic heart disease. We conclude that the pulse oximeter is a very important new diagnostic tool in pediatric cardiology.
