Enhancement of respiratory parameter estimation and undetected detection algorithm via the use of central venous pressure manometry

摘要

The respiratory monitoring device 10 includes a central venous pressure sensor 24 that measures a patient's central venous pressure (CVP) signal. At least one processor 32, 34, 36, 38, 40, 42, 44, 58 segments the CVP signal based on the detected breath interval; surrogate respiratory muscle pressure signal from the segmented CVP signal Calculating and processing the CVP signal and generating respiratory information about the patient by an action including filtering the surrogate respiratory muscle pressure signal and removing a cardiac active component of the surrogate respiratory muscle pressure signal. Has been.
