Daniel Hegerle Callie Stanley BSCI 202 Lab 3/22/16 iWorxs Report 3 Introduction A test was performed to analyze the subject’s lung volume, heart rate, and RSA. RSA stands for respiratory sinus arrhythmia , which is a heart rate irregularity during respiration. Two experiments were conducted and the subject was tested twice for each experiment. The first experiment gathered data of the subject’s normal breathing and heart rate. The second experiment gathered data from the subject during apnea. According to Professor O’Brien’s lecture, during apnea there is no movement of the muscles of inhalation and the volume of the lungs initially remains unchanged. This experiment was done to see if the hypothesis could be proven. It was hypothesized that the subject’s heart rate should change due to RSA and heart rate should decrease when holding breath and increase when breath is released. Methods After gathering all the required materials for this experiment, the subject was finger was hooked up to a plethysmograph and given a spirometer to breathe through.
