Insufflation method for introducing gas in a human or animal patient body cavity or blood vessel has a method that allows monitoring of the internal pressure based on a start pressure and the current pressure in a gas supply line

摘要

Method for insufflation of a gas into a body cavity or blood vessel in which the approximate cavity inner pressure is estimated from the cavity pressure at the beginning of insufflation and a value for an outer pressure rise in the gas supply line system during a phase of approximately constant gas flow. The invention also relates to a corresponding insufflation device.
