Abstract
An apparatus and method for anticipating side effects which are manifested in a patient during a dialysis treatment, respectively comprising a device and step for measuring at least one haemodynamic value of the patient a predetermined number of times to obtain a parameter corresponding to the variation of the haemodynamic value with respect to time, a device and step for calculating a rating corresponding to a mean variation of the parameter with reference to a predetermined period, a device and step for comparing the value of the rating with a reference value delimiting a range of safety values, and a device and step for emitting an alarm signal each time the value of the rating falls outside the range of safety values delimited by the reference value.
