Spirometric Measurements of Obese and Non-Obese Subjects in Recumbent Body Positions
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 6
Abstract
Introduction: Obesity results in progressive changes in lung function, causing a reduction in thoracic compliance, lung volumes and capacities. The aim of this study was to evaluate the influence of excess body weight on spirometry in three different recumbent body positions, evaluated by Body Mass Index. Material and Methods: 107 sedentary volunteers were distributed into three groups, based on BMI. Spirometry was performed in three different body positions- horizontal dorsal decubitus (0 degree), crook lying and 45 degree Fowler’s positions. Results: The present study found that the FVC and FEV1 values were significantly lower in HDD compared with the crook lying and Fowler’s positions in all three groups. The results also show that the spirometric values are slightly lower among obese comparing to overweight. Conclusion: This study has shown a significant postural change in lung volume and flow rates for all three groups. Thus, it is important to evaluate those obese who remain bed restricted for long periods of time, trying to maintain them more upright body position.
