Statistical Description of SaO2–SpO2 Relationship for Model of Oxygenation in Premature Infants

A pulse oximeter model linking arterial (SaO2) and peripheral (SpO2) oxygen saturation is the terminal part of a mathematical neonatal transport. Previous studies have confirmed overestimation measured by oximetry in neonates compared to large variability values over time caused measurement inaccuracies. This work aimed determine SpO2 noise that affects biased value at each point integrate description with systematic bias between SaO2 SpO2. The SaO2–SpO2 was based on previously published clinical data from pathological patients younger than 60 days requiring ventilatory support. statistical properties random were estimated continuous recordings 21 physiological neonates. result comprehensive characterization describing transfer input output value, including typical for bedside monitoring These results will help improve computer
