Background and Aim: Considering the cost and some limitations in measuring the percentage of expiratory volume in the first second (FEV1%), This study was performed to determine the relationship between oxygen saturation percentage (SPO2%) with expiratory volume in the first-second (% FEV1) in patients with chronic obstructive pulmonary disease(COPD).
Materials and Methods: In a descriptive-analytical study, 25 women and 25 men with COPD were selected by Non-probability and simple sampling from patients referred to the outpatient clinic of Vali-e-Asr Hospital regardless of the severity of the disease. To measure of % FEV1, spirometry method and a finger pulse oximeter to measure SPO2 was used.Statistical tests including Pearson test and independent t-test and linear regression model were used.
Results: The mean patient age 63.18±10.47 years,  average % FEV1 of 36.60 ± 16.15 and the mean SPO2% 84.20±5.35 was respectively. The correlation coefficient between% FEV1 and SPO2% was 0.36 (P=0.01). Mean of SPO2% in smokers and non-smoker was %82.67±5.22 and %86.50±5.29 respectively (p=0.02). Regression analysis in constant conditions showed %FEV1 By increasing one unit SPO2%, the amount of FEV1% with probability factor of 0.16 will be increased 0.36 (P=0.02).
Conclusion: The amount of SPO2% significant correlation at the medium level with the amount of %FEV1 and can predict to some extent FEV1%; Therefore, it has been diagnosed in people with obstructive pulmonary disease and it can be used for evaluation and follow-up of patients instead of spirometry.
