A process for monitoring a measuring system (110) for mechanical ventilation of a patient (20) is carried out while a fluid connection (40) is established between the patient (20) and a medical device (100). A gas sample is suctioned from the fluid connection (40) and is sent through a gas sensor fluid-guiding unit (52) to a gas sensor array (50). A time curve of the CO2 concentration and O2 concentration in the suctioned gas sample are determined. A concentration change curve of the change over time of the CO2 concentration and the O2 concentration are calculated. A search is made for a time period in which the two concentration change curves continuously have the same sign. Upon detecting such a time period it is checked whether a predefined first leak criterion is met. When this is the case, an indication of a leak (L) is detected.
