In the study, researchers from three obstetric departments in Mannheim, Germany, measured the postductal
oxygen saturation of a total of 3,364 newborns between 6 and 36h of age over a year-long period.
On his magnetic resonance angiography a postductal
coarctation and an aneurysm with a diameter of 6 cm 2 cm below the coarctation were detected (Fig.
Using Masimo technology, caregivers can measure both preductal and postductal
saturation, which may help them detect PDA.
Granelli and Ostman-Smith conducted single pre- and postductal
measurements of PI using the Masimo Radical SET Pulse Oximeter in a total of 10,000 healthy newborns (ranging in age from 1 hour to five days) and established PI reference values of healthy babies.
