Abstract
A process for monitoring a measuring system () for mechanical ventilation of a patient () is carried out while a fluid connection () is established between the patient () and a medical device (). A gas sample is suctioned from the fluid connection () and is sent through a gas sensor fluid-guiding unit () to a gas sensor array (). 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.
