Abstract
Method for ascertaining and setting a filling volume of a balloon of a catheter, which is placed in the esophagus of a living being, wherein the balloon is filled and/or emptied using a fluid. According to the invention, the balloon is filled and/or emptied step-by-step using at least two volume steps, a pressure difference between a pressure at the end of an expiration (Pmin) and a pressure at the end of an inspiration (Pmax) is determined for at least two volume steps, a relative pressure difference between Pmin and Pmax is determined, a border range is defined on the basis of the relative pressure difference, and an optimum filling volume is ascertained in consideration of the border range.
Claims19
A method for ascertaining and setting a filling volume VB of a balloon of a catheter, which is placed in the esophagus of a living being, wherein the balloon is filled and/or emptied using a fluid, the method comprising
- step-by-step filling and/or emptying of the balloon using at least two volume steps Vi;
- determining a pressure difference ΔPB between a pressure at an end of an expiration Pmin and a pressure at an end of an inspiration Pmax for at least two volume steps Vi;
- determining a relative pressure difference rΔPB between Pmin and Pmax;
- defining a border range GB on the basis of the relative pressure difference rΔPB;
- ascertaining an optimum filling volume VBopt in consideration of the border range GB.
