Noninvasive Monitoring and Assessment of Oxygenation in Infants
2019, Clinics in PerinatologyCitation Excerpt :This procedure may lead to an underestimation of the true degree of hypoxemia and has led to recommendations that every patient with baseline SpO2 values less than 75% to 80% should have her or his arterial blood oxygen saturation determined to measure the true severity of the hypoxemia.41 However, analysis of the data plots from several validation studies, some of which included a high proportion of low SaO2 values (Table 3), suggests that the pulse oximeter’s sensitivity to hypoxemia (SaO2 <80%) is not as bad as might be inferred from the previous considerations.22,42–55 However, these data were obtained under optimal measurement conditions and may not be transferable to routine clinical conditions in which there is frequent motion artifact.
Oxygen titration strategies in chronic neonatal lung disease
2010, Paediatric Respiratory ReviewsCitation Excerpt :Assessment of SpO2 can be made in different behavioural states and using different machines. An oximeter which measures fractional oxygen saturation (e.g. Ohmeda 3470), may read 1.6% lower than one measuring functional saturation (e.g. Nellcor N3000).8 Fractional saturation refers to the ratio of oxyhaemoglobin to all haemoglobin measured, including dyshaemoglobins (e.g. carboxyhaemoglobin or methaemoglobin), whereas functional saturation refers to the ratio of oxyhaemoglobin to all haemoglobin that is capable of carrying oxygen.
