Abstract: A process is provided for the automatic control of a respirator for changing over (triggering) between consecutive phases of respiration (inspiration and expiration phases), wherein a pneumatic breathing activity signal upneu(t) and a non-pneumatic breathing activity signal unon-pneu(t) of a patient are picked up. The intervals ?pneu(t) and ?non-pneu(t) to the associated threshold variables are respectively determined starting from a preset reference point in time since the beginning of the present phase of respiration. The intervals are standardized to one another at ?pneu(t) and ?non-pneu(t), such that the intervals have equal interval values at a preset reference point in time. The standardized intervals ?pneu(t) and ?non-pneu(t) are averaged to a mean interval indicator and a changeover is made into the next phase of respiration when the combined interval indicator is 0.

Abstract: A self-locking T-piece connects an attachment to a breathing gas line. The self-locking T-piece has a line section (2), a connection line (4) branching off therefrom, a movable valve body (10) with a valve disk (12), and a valve seat (14). The valve body (10) is prestressed by a spring (16) into a position to seal the connection line (4) against the line section (2), with the valve disk in the valve seat, and moves out of the sealing position when connecting the attachment to the connection line. The valve body (10) is elastically deformable such that it can be advanced through the connection line (4) and the valve seat (14), while undergoing elastic deformation, and returns to its original shape during the entry of valve disk (12) into the line section, in which it has a sufficient extension to be able to cover the valve seat for sealing.

Abstract: A method implemented, e.g., as software and a device operating according to the method for the automatic evaluation and analysis of a capnogram are provided. Measured values for an expired volume—volume measured values—and measured values for a carbon dioxide concentration—concentration measured values—are recorded for the breathing gas of a test subject. An automatic approximation of at least one part of the curve of the concentration measured values over the volume measured values is performed, by using three mutually adjacent straight lines for the approximation. The area is determined using the third straight line according to Fowler for the determination of the serial dead space Vds.
