In this study, it was investigated whether the gas concentration delivered to the patient, shows changes depending on the length of the delivery tubing or not. The length of delivery tubing is important during performance tests of anesthesia vaporizer, because it may be shortened or extended if it is required. But its material type and its width does not change. To investigate the effect of length of delivery tubing, the performance test of anesthesia vaporizer may be performed for the tubes with different lenghts. In this study, for 3 different length of delivery tubing (A: 48cm, B: 100cm and C: 150cm), sevoflurane and isoflurane concentration measurements were performed. Because 5 different vaporizers were measured for each length of delivery tubing, totally 30 measurements (15 isoflurane and 15 sevoflurane) were performed. For the concentration measurements, PF301 Flow analyser (imt medical-Switzerland) and OR703 Multi Gas analyser (IRMA AX) were used. Measurement procedure were obtained from Inspection and Preventive Maintenance System (IPM) of Emergency Care Research Institute (ECRI). For sevoflurane; measurements were taken in the scale of 1%, 2%, 3%, 4%, 5%, 6% and 8%, whereas for isoflurane, were taken in the scale of 1%, 2%, 3%, 4% and 5%. Measurements were performed with an oxygen flow of 5L/min. The measurement results were investigated statistically and their mean and standard deviation were calculated. As a result, it was seen that, anesthesia vaporizers give concentrations close to each other, independently with the length of delivery tubing. There was no any gas absorption as like expected.
