1. A medical apparatus for use in laparoscopic surgery, comprising:
an insufflator supplying a gas,
a heating and humidification system which includes a heating element and humidification material, the heating and humidification system receives the gas supplied by the insufflator and warms and humidifies the gas; and
a computing device for measuring at two or more time periods a resistance value associated with a component of the heating and humidification system and based in part on the measured resistance values, determines a water content of the humidification material;
wherein the resistance value associated with h component of the heating and humidification system increases linearly in a temperature range of 0-100 degrees Celsius.
