How to prevent the cuff pressure increasing during inhalation anesthesia?

Summary:The relationships between the pressure in the tracheal tube cuff with the components of inflation gases and inhalation gases were examined by the simulation technique based on the gas transmission theory. We demonstrated that nitrous oxide gas in the inhalation gases transmitted in through cuff material so as to increase the cuff pressure, whereas carbon dioxide gas in the inflation gases moved out through cuff material and exerted to decrease the cuff pressure. These results show that a certain amount of carbon dioxide gas may compensate the transmission of nitrous oxide gas and keep the cuff pressure constant during nitrous oxide anesthesia.
