The reproducibilities of the FDA negative pressure leak test and anesthesia machine internal circuit low flow leak test, methods to detect internal circuit leaks of anesthesia machines, were compared through three continuous measurements by these two methods on nine anesthesia machines of the same type. Five of the nine machines showed matching results between the two methods and good reproducibility. The remaining two machines showed matching results, but inconsistency in the measured values with the FDA universal negative pressure leak test, apparently due to changes in the negative pressure of the rubber ball with each measurement. Results did not match in two machines, the cause of which is unknown. The anesthesia machine internal circuit low flow rate leak test is considered to have better reproducibility than the FDA universal negative pressure leak test, and to be highly reliable.
