Abstract

The application relates to a system for monitoring respiratory effort in a patient (3), comprising at least one pressure sensor (2), the pressure sensor being positioned in a catheter (1) and being adapted for positioning in a chosen position in the esophagus (5), the pressure sensor being adapted to monitor the pressure in the esophagus at a chosen resolution providing a time series of pressure having a chosen length. The system comprising calculation means for splitting the time series into a number of time windows, each window comprising at least one respiration cycle - a time series containing two crossings of a predefined zero value in the same direction - calculating the respiratory effort index indicating the pressure amplitudes within each time window thus providing a set of characteristic values for each time window comprising said respiratory effort index and the length of each time window.
