摘要： The present disclosure pertains to a system and method for monitoring lung disease in a patient that is based on information that is derivable from home therapy devices including a ventilation therapy device and an oxygen saturation monitor such as a pulse oximeter. The measured parameters are used to model shunt fraction and a volume of dead space. Based on changes in gas exchange and results of a nitrogen washout test, a change in gas exchange impairment in the patient is observed and is then used to determine progression of a disease, identify a cause of the impairment, and/or to guide treatment of the patient.

摘要： When estimating respiratory muscle pressure and respiratory mechanics using a P0 .1 maneuver patient inspiration onset for a patient connected to a ventilator (64) is detected, and the airway of the patient is occluded for a first predetermined time period. A first respiratory muscle pressure (P mus ) profile is estimated during the airway occlusion. Resistance (R) and compliance (C) values and a second P mus profile generated during a second predetermined time period are then estimated. A third P mus profile is estimated during a third predetermined time period that extends from the end of the second predetermined time period until the end of inspiration. P mus (t) over an entire breath is estimated by concatenating the first, second and third P mus profiles, and the estimated R and C values and the estimated P mus profiles are output on a display.

摘要： A mechanical ventilator (10) provides pressure support ventilation (PSV) to a patient (12). A power of breathing (PoB) or work of breathing (WoB) estimator (30) generates a PoB or WoB signal (34) for the patient. An error calculator (36) computes an error signal as a difference between the PoB or WoB signal and a set point PoB or WoB value (22). A controller (20) inputs a PSV control signal (24) equal to the product of the controller transfer function and the error signal to the mechanical ventilator. A patient adaptation component (52, 54, 56, 60) fits parameters of a model of a controlled mechanical ventilation system comprising the mechanical ventilator and the patient to data comprising the PoB or WoB signal and the PSV control signal generated by the operating closed loop controller, and adjusts parameters of the controller transfer function to maintain stability of the operating closed loop controller.
