Abstract: A respiration monitoring device includes at least one electronic processor programmed to perform a respiration monitoring method including receiving ultrasound imaging data of a diaphragm of a patient as a function of time during inspiration and expiration while the patient undergoes mechanical ventilation therapy with a mechanical ventilator; receiving respiratory data of the patient as a function of time during the inspiration and expiration while the patient undergoes the mechanical ventilation therapy; calculating an intrinsic positive end-expiratory pressure (iPEEP) value for the patient based on the ultrasound imaging data and the respiratory data; and displaying, on a display device, a representation of the calculated iPEEP value.

Abstract: A mechanical ventilation assessment assistance device includes at least one electronic processor; and a non-transitory storage medium storing instructions readable and executable by the at least one electronic processor to perform a mechanical ventilation assessment assistance method including obtaining an image of a patient (P) receiving mechanical ventilation; generating or updating a patient-specific lung model of at least one lung of the patient based on the obtained image; simulating a response of the patient to a mechanical ventilation therapy using the generated or updated patient-specific lung model; comparing the simulated response with an actual response of the patient to the mechanical ventilation therapy; based on the comparison, determining an imaging recommendation for acquiring an image of at least one lung of the patient; and outputting the determined imaging recommendation.

Abstract: A diaphragm imaging device includes at least one electronic processor programmed to perform a diaphragm imaging method including receiving ultrasound imaging data of a diaphragm of a patient, the ultrasound imaging data being acquired by an associated ultrasound imaging probe with the probe at a plurality of different observable probe angles (βobs); for each observable probe angle, determining a corresponding apparent thickness (dI) of the diaphragm of the patient from the received ultrasound data acquired at that observable probe angle; and estimating a thickness (dD) of the diaphragm of the patient based at least on the apparent thicknesses (dI).

Abstract: According to an aspect, there is provided a system for determining a level of oxygen consumption of a patient, comprising: an inhalation limb configured to transport a first gas for inhalation by a patient; an exhalation limb configured to transport a second gas exhaled by the patient; a patient interface assembly connected to the inhalation limb and the exhalation limb, the patient interface assembly to transport the first gas to the patient and the second gas from the patient; a first oxygen sensor configured to measure a concentration of oxygen in the second gas at a first sampling region; a first carbon dioxide sensor configured to measure a concentration of carbon dioxide in the second gas at a second sampling region; a flow rate sensor configured to measure a flow rate of the first gas or the second gas; and a processor configured to determine a level of oxygen consumption of the patient using an indication of a concentration of oxygen in the first gas, an indication of a concentration of carbon dioxide in the first gas and data obtained via the first oxygen sensor, the first carbon dioxide sensor and the flow rate sensor.

Abstract: A computer-implemented method is described. The method includes receiving an indication and determining a subject's oxygen consumption based on the indication. The indication refers to an oxygen fraction in a sample of inhalation gas delivered by a ventilator for inhalation by a subject. The indication further refers to an oxygen fraction in a sample of exhalation gas exhaled by the subject. The indication further refers a measurement of a flow rate of the exhalation gas.
