1. A method for risk assessment of a critical hemodynamic event of a patient, comprising the steps of:

  • measuring a set of values of physiological parameters, said physiological parameters including heart rate (HR) and pulse arrival time (PAT), wherein said set of values includes a heart rate (HR) value and a pulse arrival time (PAT) value, andperforming a risk assessment by a calculating device, said risk assessment including the allocation of a representation of the measured set of values as a two-dimensional vector {right arrow over (R)}(t) in a two-dimensional vector space to a risk level representing the risk of the occurrence of a critical hemodynamic event.Wherein a first dimension of the two-dimensional vector represents the heart rate (HR) value and a second dimension of the two-dimensional vector represents the pulse arrival time (PAT) value,Wherein the allocation is based on a combination of the heart rate (HR) value and the pulse arrival time (PAT) value in the vector, which combination represents the risk, andDisplaying the vector {right arrow over (R)}(t) within the vector space.
