SYSTEMS AND METHODS FOR ESTIMATION OF RESPIRATORY MUSCLE PRESSURE AND RESPIRATORY MECHANICS USING P0.1 MANEUVER

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.
