Patent ID: 8728002

Claim:
A method for real time estimation of at least one selected from the group consisting of C RS (respiratory system compliance), R RS (patient airway resistance), and P plt inspiratory plateau pressure, comprising: (a) receiving respiratory parameters of a patient from a device that interfaces with patient pulmonary system and measures the respiratory parameters; (b) calculating, with a processor unit, the patient's τ E (expiratory time constant) using at least one respiratory parameter from step (a), and (c) calculating with the processor unit at least one estimate selected from the group consisting of C RS , R RS , and P plt , using at least one respiratory parameter from step (a) and the patient's τ E from step (b), wherein the at least one respiratory parameter used to calculate the patient's τ E is from exhalation and wherein the at least one respiratory parameter used to calculate at least one real time estimate selected from the group consisting of C RS , R RS , and P plt , is from inspiration.
