Determination of the Best Resting Position Using Electrogastrography After Having a Light Meal

Rest is necessary for a cyclic manner or after getting tired to refresh our mind and restore the body's metabolism for regular activity. There are several resting positions, e.g. left, right, soldier (supine), and free-fall (stomach), but not all positions are not equally comfortable or healthy. Incorrect resting positions may have a detrimental effect on the rest or health benefits. In this work, the impacts of various resting positions were assessed based on variation in stomach function analyzing Electrogastrogram (EGG) along with different physiological parameters, e.g. Electrocardiogram (ECG), heart rate, oxygen saturation (SpO2) and respiratory rate, etc. Ten healthy young adults were undergone through the experiment. To find the best resting position after having a light meal, EGG, ECG, SpO2, and respiration rate were collected for analysis in the left, right, and supine position. The dominant frequency components of EGG were calculated from all subjects. A regular and stable EGG with a dominant frequency component of (3.02±0.43) cycle per minute was found in the supine position with the lowest variability. The Variability in the respiration rates were also lower at the supine position (16.8±1.03) than in comparison with either left (16.0±2.05) or right (16.40±1.84) positions. Oxygen saturation is also found maximum in the supine position. Therefore, the supine resting position is strongly suggested for an individual during the rest.
