Assignee: KONINKLIJKE PHILIPS N.V.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A system comprising:
one or more physical processors programmed with computer program instructions which, when executed, cause the system to:
determine breath segmentation data indicating a first time associated with an onset of respiratory effort and a second time associated with an end of inhalation of a breathing patient receiving support from a ventilator;
use: (a) a difference in airway flow values sampled at the first time and during exhalation; and (b) airway volume values sampled during the exhalation determine a respiratory time constant value;
use the respiratory time constant value in combination with airway pressure values and the airway flow values sampled at the first time and the second time, and an airway volume value sampled at the second time, to thereafter recover one or more of respiratory resistance and respiratory elastance; and
provide, using the one or more of the respiratory resistance and respiratory elastance, a parameter of respiratory mechanics in a presence of an intrinsic positive end-expiratory pressure (PEEPi)
as input to the ventilator, causing an adjustment of one or more settings of the ventilator.
