The Effect Of Cardiac Surgery On The Human Respiratory System

Introduction Heart and lung work hand to hand daily, nonstop until we die. Some people may have experienced heart surgery because of many reasons. Some reasons for cardiac surgery is tumor, heart attack, blood clot in the heart, etc. After the surgery, there is a recovery process and the heart may not even fully heal for some patients. Since the heart may not be able to work optimally, respiration system of the patients may also be affected (Westerdahl et al, 2016). The surgery process itself may also affect the respiratory system by traumatizing the cells and muscles in general, thus reducing the capacity of the lung for respiring and breathing. One study suggests that the thoracic cavity may also have been traumatized by the surgery and difficult to get back into the previous full function (Vargas et al, 1997). If the heart cannot pump blood properly to the lungs, the lungs may not be able to perform optimally as well because the blood circulation through the lungs alveoli may not be distributed to its maximum potential (Westerdahl et al, 2002).

The subjects are selected randomly, from the age of sixty through the age of eighty years old, male and female, and from all over the world so that the data may be applicable worldwide. This study do not check for other diseases that they might have. Each person will be tested for their vital capacity through the spirometer. The data recorded is the highest number in the spirometer, and then calculate the percent vital capacity. After all the vital capacity percentage is recorded, they are being averaged and calculate the standard
