A nonlinear association was found between Spo2/Fio2and Pao2/Fio2. Considering the possible confounding factors of the pulse oximeter on the relationship between Spo2/Fio2and Pao2/Fio2ratio, arterial pH, and Paco2had no effect. Spo2/Fio2and Pao2/Fio2ratio demonstrated a moderate agreement in ...
Chronic hypoxaemia, is defined by O'Driscoll et al (2008) as a low oxygen tension or partial pressure of oxygen PaO2 <60 mmHg in the blood, or SpO2 <90% on room air. Home oxygen therapy assessment for COPD patients discharged from hospital: respiratory NP model of care Girdle area was ...

(R: 0.227, p < 0.0001), D-Dimer (R: − 0.240 p < 0.0001), age (R: − 0.347, p < 0.0001), SpO2 (R: 0.258, p < 0.0001) in the overall population; no correla- tion was observed between P/F ratio and serum creatinine (R: − 0.022, p =...
Corresponding measurements of Spo2 and Pao2 from patients enrolled in the National Heart, Lung, and Blood Institute ARDS Network trial11 comparing tidal volumes of 6 mL/Kg predicted body weight (PBW) with those of 12 mL/kg were utilized to establish the relationship between S/F and P/F ratio...
S/F ratio – SpO2/FiO2; P/F ratio – PaO2/FiO2. The line represents the best fit linear relationship SpO2/FiO2 = 0.80(PaO2/FiO2) + 59.8 (p < 0.001). The SF ratio could be predicted well from PF ratio, described by the linear regression equation SpO2/FiO2 = 0.80 (PaO2/FiO2) + ...
Then spo2, Fio2, Pao2 charted within 5 minutes were measured and the ratio of SF and PF were calculated and compared. SF threshold the values were determined to replacement PF ratio for diagnose ARDS and ALI. Results: The relationship between SF and PF ratio was described by the following ...
The objectives of this study were to derive Spo2/Fio2 (SF) ratio correlations with the Pao2/Fio2 (PF) ratio to calculate the respiratory parameter of the SOFA score, and to validate the respiratory SOFA obtained using SF ratios against clinical outcomes. PATIENTS AND MEASUREMENTS: We obtained ...
sectional study, we enrolled 70 patients with ALI or ARDSwho were admitted in Tabriz children’s hospital pediatrics intensive care unit (PICU).Spo2, Fio2, Pao2, charted within 5 minutes of each other and calculated SF and PFwere recorded to determine the relationship between SF and PF ratio....
To ensure an accurate measure of oxygen saturation and identical acquisition time as the PaO2, SaO2 rather than SpO2 was utilized. Due to the non-linear relationship between SaO2 and PaO2 at extreme values, samples were restricted to the range of 75% to 92%. We further restricted the sample...
