1. A method of determining a cardiovascular parameter reflecting preload dependence, fluid responsiveness or, volume responsiveness comprising:

  • receiving a waveform dataset corresponding to an arterial blood pressure, or a signal proportional to, or derived from, the arterial blood pressure signal;

    detecting an irregular cardiac cycle;

    compensating for the effect of the irregular cardiac cycle to form a modified waveform dataset; and

    calculating a cardiovascular parameter reflecting preload dependence, fluid responsiveness, or volume responsiveness using the modified waveform dataset.
