Abstract
A method for non-invasive determination of a hemodynamic parameter of a mechanically ventilated subject based on a point in time (t) of a heartbeat of the subject and an arrival point in time (t) at which a blood pressure pulse caused by the heartbeat reaches the lungs of the subject. The method includes the steps of measuring a respiratory pressure and/or a respiratory flow, and determining the arrival point in time (t) from a change in the measured respiratory pressure and/or the respiratory flow resulting from a change in lung volume caused by the arrival of the blood pressure pulse to the lungs of the subject.
