Abstract
An endoscope system includes a gas feeding apparatus that feeds carbon dioxide, and a light source apparatus provided with an air pump for supplying air. The endoscope system feeds the carbon dioxide or the air from a distal end of an endoscope when a gas/liquid feeding button provided to the endoscope is operated. The endoscope system includes a pressure meter and a processor. The pressure meter is provided inside the gas feeding apparatus and configured to detect a pressure of the carbon dioxide. The processor is configured to perform control for stopping feeding of the air by the air pump when determining that, after the carbon dioxide is fed by an operation of the gas/liquid feeding button, the pressure of the carbon dioxide detected by the pressure meter reaches a predetermined threshold.
