“…10,[12][13][14][15] All but one study 10 showed limited usefulness of SaO 2 of this magnitude in predicting hospitalization, with posttest probability of hospitalization of 45% to 55%. 17 Geelhoed et al 10 found that children with SaO 2 of 91% or less were significantly more likely to be either admitted to hospital or to have a return visit to the ED.…”

“…Studies assessing the value of baseline oximetry as a predictor of hospitalization in asthma have yielded variable results, with some detecting benefit 10,11 and others not. [12][13][14][15][16][17] Only three studies have examined SaO 2 as an independent predictor. 10,13,17 However, these studies did not use a clinical asthma score; therefore the association between the severity of the index episode and the SaO 2 could not be determined.…”

“…[6][7][8][9] In studies looking at pulse oximetry alone as a predictor for admission for an acute AE showed it was not useful. 20,22,23 In these studies, it was possible that some subjects who were admitted and had a high normal pulse oximetry, may have had VCD as the primary cause of their respiratory distress as there was no specific mention of assessing for VCD. Additionally hyperventilation could be another source of persistent dyspnea when there is high normal pulse oximetry.…”

“…Several studies demonstrated the importance of arterial oxygen saturation (SaO 2 ) in the assessment of respiratory distress in bronchial asthma [1, 2, 3]. Moreover SaO 2 has been used in the diagnosis of pneumonia specifically in the developing countries, where a good correlation between low SaO 2 levels and pulmonary opacities on chest X-rays is observed in infants and children [4, 5, 6, 7].…”

Background: The importance of SaO₂ in the assessment of respiratory distress in bronchial asthma has been reported. Objectives: To evaluate the correlation between blood gas analysis and chest X-ray lung opacities in young children presenting with acute respiratory symptoms. Methods: Eighty patients (43 males and 37 females aged 0.5–24 months; mean ± SD 9.1 ± 7.2 months), either with acute wheezing respiratory symptoms and/or with crackles were enrolled in our study. In all children, blood gas analysis and chest X-rays were performed within 12 h following admission to the emergency department. Results: In 55 children (68.75%) chest X-rays demonstrated lung opacities. Subjects with normal X-rays had paO₂ and SaO₂ higher than subjects with lung opacities (p < 0.0001 and p = 0.0001, respectively). Children with lung opacities almost always presented paO₂ <80 mm Hg. Sensitivity and specificity for the presence of lung opacities of paO₂ <80 mm Hg were 81 and 90%, respectively, while sensitivity and specificity of SaO₂ <95% were 92 and 40%, respectively. paO₂ <80 mm Hg in association with SaO₂ <95% had a positive predictive value for the diagnosis of pneumonia of 90.9%. Conclusions: Our study suggests that blood gas analysis, particularly paO₂, may help in predicting the presence of lung opacities in patients aged less than 2 years. However, chest X-rays may still be needed to define the actual extension of opacities as well as the possible concomitant presence of complications.
