SYSTEM FOR DETECTING RESPIRATORY MUSCLE ACTIVITY OF A PATIENT RECEIVING ASSISTED BREATHING

摘要

the detection system of the activityrespiratory muscle of a patient (1)respiratory assistance device, connected to asupport (2) with a pneumatic circuit (3).the system is characterized in that theincludes: means (4, 5) for the acquisition ofthe signals of pressure and flow of the air in thepneumatic circuit (3) formeans (6) for estimating continuouslythe theoretical pressure of the air in the pneumatic circuit as expectedthe absence of respiratory muscle activity of the patient; andmeans (7) for comparison of estimated and measured pressure theoryin order to detect a continuous pressure differencerepresentative of a patient's respiratory muscle activity.
