The invention provides early feedback to clinician or caregiver so that they may characterize the adequacy of the cardiorespiratory system over short-term time intervals. In that way, any deficiencies may be readily detected and treated before the patient's compensatory capacity is compromised. In one embodiment, a biological signal, having a waveform, is processed for deriving a perfusion parameter and a baseline value for the perfusion parameter. The invention monitors, in real time, the derived perfusion parameter and determines a variation of the computed perfusion parameter from the baseline value. The determined variation of the derived perfusion parameter is evaluated with respect to at least one variation threshold. A duration of time associated with the determined variation is measured that is reflective of the amount of time the derived perfusion parameter variation is above or below the at least one variation threshold. Based on the evaluation of the derived perfusion parameter with respect to the at least one variation threshold and the measured duration of time, a cardiovascular stress index is determined for the patient.
