Positional OSA in the Morbidly Obese and the Effect of Weight Loss on OSA Severity
2015
Obesity has been shown to be a significant risk factor for OSA [1], yet screening for OSA in morbidly obese patients undergoing bariatric surgery is rarely performed. A study by Ravesloot et al. reported that approximately 70 % of patients undergoing bariatric surgery are diagnosed with OSA [2]. In this chapter we will discuss the prevalence of POSA in patients undergoing bariatric surgery and the influence of bariatric surgery on POSA. Furthermore, BMI, neck circumference, AHI, and age as predictors for POSA will be evaluated.
