Accuracy of Oxygen Saturation Measurements in Patients with Obesity Undergoing Bariatric Surgery

Background We aimed to determine the magnitude, direction, and influencing factors of the concordance between arterial oxygen saturation (SaO 2 ) and peripheral capillary oxygen saturation (SpO 2 ) in patients with obesity undergoing bariatric surgery, supporting the measurement of SaO 2 and SpO 2 i...

Description
Summary:Background We aimed to determine the magnitude, direction, and influencing factors of the concordance between arterial oxygen saturation (SaO 2 ) and peripheral capillary oxygen saturation (SpO 2 ) in patients with obesity undergoing bariatric surgery, supporting the measurement of SaO 2 and SpO 2 in key populations. Methods Patients with obesity undergoing bariatric surgery from 2017 to 2020 were included. Preoperative SpO 2 and SaO 2 were collected. Linear correlation and multiple linear regression analyses were performed to characterize the relationships between body mass index (BMI), age, and sex with pulse oximetry and arterial blood gas (ABG) parameters. Bland–Altman analysis was applied to determine the concordance between SpO 2 and SaO 2 and the limits of this concordance. Results A total of 134 patients with obesity undergoing bariatric surgery were enrolled. SaO 2 was negatively associated with BMI ( p
