Method for automatic recording of pressure-volume curves in artificial respiration and apparatus for carrying out the method

摘要

The invention relates to a method for the automatic recording of pressure-volume curves in artificial respiration with a ventilator, is increased under the control of a control unit inspiratory pressure upon delivery of a respiratory gas volume flow, the resulting respiratory gas volumetric flow detected and determined from the latter, the volume by integration becomes. According to the invention, the control unit compares the detected respiratory gas volume flow in the expiration phase with a preselected setpoint value and, in the event of a deviation from the setpoint value, acts on an exhalation valve (12) in the expiratory line (8) to return the respiratory gas volume flow to the desired value.
