Abstract
A ventilation control unit (), regulating a gas flow () within a ventilation system (), includes a reception module (), first and second calculation modules () and an output module (). The reception module has a signal interface () receiving inspiratory and expiratory flow signals () at regular time intervals. The first calculation module calculates a leak flow () based on a difference between the current inspiratory gas flow and the current expiratory gas flow, with an external gas flow source () separated from a ventilation circuit of the ventilation system. The second calculation module calculates an external gas flow () after connecting the external gas flow source to the ventilation circuit based on the leak flow and the difference between the current inspiratory gas flow and the current expiratory gas flow. The output module outputs an output signal (), based on the external gas flow.
