Abstract
A gas feeding apparatus configured to supply the gas to a lumen of a patient through a gas feeding conduit provided in an endoscope, the gas feeding apparatus including: a flow rate sensor configured to measure a flow rate of the gas in the gas feeding conduit; and a control circuit configured to time-sequentially calculate an integrated amount of the gas fed to the lumen in a period from a first timing to a second timing, the first timing being a timing when the gas starts to be fed from the gas feeding conduit to the lumen by an operation of a gas feeding button of the endoscope, the second timing being different from the first timing. The control circuit controls a notification unit to activate an alarm, when the integrated amount of the gas reaches the first threshold.
