Abstract: The present disclosure relates to a method for non-invasive determination of a hemodynamic parameter of a mechanically ventilated subject (3) based on a point in time (thb) of a heartbeat of the subject and an arrival point in time (tarr_pulm, tarr_sys) at which a blood pressure pulse caused by the heartbeat reaches a point of arrival in the circulatory system of the subject. The method comprises the steps of measuring (S41) a respiratory pressure and/or a respiratory flow, and determining (S43) the point in time (thb) of the heartbeat from a change in the measured respiratory pressure and/or the respiratory flow resulting from a physical impact of the heart on the lungs of the subject (3) during the heartbeat.

The method comprises the steps of measuring (S31) a respiratory pressure and/or a respiratory flow, and determining (S33) the arrival point in time (tarr_pulm) 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.
