Patent ID: 6228033
Filing Date: 2001-05-08
Classification: A61B

Abstract:
An apparatus for a simultaneous/synchronized noninvasive measurement of cardiorespiratory and related parameters comprisinga bioimpedance measuring means (5) connectable to the body of the patient for injecting a current to a first outer body segment and sensing the voltage in the first and second inner body segments for generating output signals (53, 54, 55, 56, 57), characterized in that the apparatus further comprisesa pressure sensoring means (6) for the measurement of blood pressure, said sensoring means being connected to the bioimpedance measuring means (5) for generating a blood pressure output signal,a respiratory flow sensor (7) for measuring the patient's respiration continuously, said respiratory flow sensor being connected to the bioimpedance measuring means (5) for generating a respiratory flow output signal, anda calculating means (83) for calculating cardiorespiratory and related parameters using said output signals.
