Experiment using a simulator to determine how condensation forms on the access port. The experimental simulator was floated on a water bath warmed to 37 °C, mirroring the abdominal cavity. The access port of the AirSeal was placed on the simulator, and the tri-lumen tube was connected from the body of the AirSeal system to the access port. The AirSeal system was switched on, and insufflation was started at a flow rate of 40 L/min and pressure of 10 mmHg. A silicone rubber heater was wrapped around the tri-lumen tube.
