Abstract
A respirator for breath-supporting respiration has improved sensitivity of triggering breathing support. A pre-inspiratory inspiratory gas flow is set, which flows off via the expiration valve (). The closing pressure pof the expiration valve is measured with a pressure sensor () in the process. The gas flow is increased in case of an inspiratory effort of the patient to the extent that the closing pressure pof the expiration valve () is restored. Breath support is generated when the difference between the preset gas flow and the gas flow that is needed to maintain the closing pressure pat a constant level exceeds a predetermined threshold value.
