Abstract

See full text

A process (10), with a computer program, a device (30) and a ventilation system (40) detect a leak in a patient gas module, which suctions and analyzes a continuous sample gas stream from a ventilated patient (20), in a ventilation system for ventilating a patient (20). The process includes a determination (12) of a first time curve of a carbon dioxide concentration in a breathing gas mixture of the patient (20) and the determination (14) of a second time curve of a concentration of another gas in the breathing gas mixture, which gas is different from carbon dioxide. The process (10) further includes a determination (16) of a statistical similarity indicator between the first time curve and the second time curve and the detection (18) of the leak based on the similarity indicator.
