RESPIRATION MONITORING

摘要

The invention, relates to a system for monitoring respiratory effort in a patient, comprising at least one pressure sensor, the pressure sensor being positioned in a catheter and being adapted for positioning in a chosen position in the esophagus, 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.
