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