Measurement of condensation volume on access port in simulator model. The experiment was performed using the abdominal simulator and different temperatures of the tri-lumen tube (4 °C, room temperature, and 37 °C). The volume of the condensation on the inside and outside of the wall of the access port was measured every 30 min for 2 h in the each of the three groups and compared among the groups (i.e., Control, Cooled, and Heated groups). (a) The condensation volume on the inside wall of the access port was lower in the Heated and Control groups than in the Cooled group. (b) The accumulated weight of the condensation on the inside wall of the access port was significantly lower in the Heated and Control groups than in the Cooled group. (c) The condensation volume attached to the inside wall of the access port was lower in the Heated group than in the Cooled and Control groups. (d) The accumulated weight of the condensation on the inside wall of the access port was lower in the Heated group than in the Cooled and Control groups.
