“…PEF change more than 50 L/Min of basic amount and more 40% of estimated amount show good prognosis [4]. In studies by Boychuk, Martin, Weber and coworkers they showed that 15%, 10.5% and 20% of patients referring with asthma attack symptoms were hospitalized, respectively [6][7][8]. In our study, 54.4% of patients were hospitalized that were more than other studies.…”

“…Significant changes in lung function may be present despite the lack of clinical manifestations (1,2,6), as first reported in the 1970's (1) and confirmed by subsequent studies (2)(3)(4)(5)(6)(7)(8)(9). The severity of acute asthma is classified as mild, moderate, severe, and very severe based on clinical and functional criteria (10), the most widely used being pulse oximetry (SpO 2 ) and peak expiratory flow (PEF).…”

Few studies are available concerning correlations between pulse oximetry and peak expiratory flow in children and adolescents with acute asthma. Although the Global Initiative for Asthma states that measurements of lung function and oximetry are critical for the assessment of patients, it is not clear if both methods should necessarily be included in their evaluation. Since there is a significant difference in cost between pulse oximetry equipment and peak expiratory flow devices, we determined whether clinical findings and peak expiratory flow measurements are sufficient to determine the severity of acute asthma. The present prospective observational study was carried out to determine if there is correlation between pulse oximetry and peak expiratory flow determination in 196 patients with acute asthma aged 4 to 15 years diagnosed according to the Global Initiative for Asthma criteria. Patients experiencing their first or second wheezing episode, with fever, related acute or chronic diseases, and unable to perform the peak expiratory flow maneuver were excluded. Measurements of peak expiratory flow and pulse oximetry were performed at admission and after 15 min of each inhaled salbutamol cycle. Correlations obtained by linear regression using the Pearson correlation coefficients (r) were 0.41 (P < 0.0001), 0.53 (P < 0.0001), 0.51 (P < 0.0001), and 0.61 (P < 0.0001) at admission and after the first, second and third cycles of salbutamol, respectively. These correlations showed that one measure cannot substitute the other (Pearson's coefficient <0.7), probably because they evaluate different aspects in the airways, suggesting that peak expiratory flow should not be used alone in the assessment of acute asthma in children and adolescents.

“…Pulse oximetry is an accurate, simple and noninvasive method for measuring arterial oxygen saturation, and it can reliably detect desaturation in wheezing children (15,16). Initial SaO 2 has been shown to be the dominant predictor of hospitalisation in wheezing children and, in this study, levels of 90-93% effectively predicted the severity of the wheezing in children aged at least 6 months, which was measured in terms of their length of stay in hospital (9). This was the case even when the patients with an initial SaO 2 of below 90% were analysed separately.…”
