PROBLEM TO BE SOLVED: To provide a system and method for calculating accurate estimated values of pulmonary mechanics of a patient, including but not limited to compliance, resistance, and plateau pressure without modification of ventilator flow pattern.SOLUTION: Accurate estimated values of pulmonary mechanics are derived from airway pressure and flow sensors 5 attached to a patient using novel mathematical models. These estimated values for pulmonary mechanics (respiratory system compliance and resistance) are important for monitoring patient treatment efficacy during mechanical ventilation and ensuring alveoli do not overdistend to surely avoid barotrauma and/or volutrauma, especially in patients with restrictive lung diseases. The method for calculating these accurate estimated values for pulmonary mechanics is based on linear or nonlinear calculations using multiple parameters obtained from the above-mentioned sensors.SELECTED DRAWING: Figure 1 |
