Abstract: The present disclosure pertains to a system and method for monitoring lung disease in a patient that is based on information that is derivable from home therapy devices including a ventilation therapy device and an oxygen saturation monitor such as a pulse oximeter. The measured parameters are used to model shunt fraction and a volume of dead space. Based on changes in gas exchange and results of a nitrogen washout test, a change in gas exchange impairment in the patient is observed and is then used to determine progression of a disease, identify a cause of the impairment, and/or to guide treatment of the patient.

Abstract: An embodiment includes use of a predictive model to ascertain a likelihood of a patient having expiratory flow limitation (EFL) to adjust the application of ventilator-based therapy. An embodiment may operate one or more predictive model on patient data alone to obtain a prediction of EFL for the patient, avoiding a need to perform invasive or ventilator based EFL detection, e.g., via a forced oscillation technique (FOT). An embodiment may be used in a system or method that adjusts ventilator settings for respiratory therapy, for example to abolish detected EFL in a patient having a positive classification for EFL.

Abstract: X-ray sources emit X-rays into an examination region along different projection views. An X-ray detector array detects the X-rays emitted by the X-ray sources after passing through the examination region. X-ray imaging data are acquired by cycling through the X-ray sources with each step of the cycle including: switching an active X ray source on to emit X-rays and the other X ray sources off to not emit X rays, and acquiring X ray imaging data along the projection view corresponding to the active X-ray source that is switched on. Tomosynthesis image reconstruction is performed on the X ray imaging data to generate at least one volumetric image. A time sequence of spatially aligned images is produced from the time sequence of volumetric images. A perfusion image and/or a ventilation image is generated based on voxel intensity variation over time of the time sequence of spatially aligned images.

Abstract: A proning assessment method includes determining, from received respiratory and/or body position data, a flipping time (tflipping) when a patient is placed in a partial or full prone position; determining a target imaging time (timg,target) for acquiring imaging data to assess an impact of proning on mechanical ventilation therapy as the flipping time (tflipping) plus a predetermined time interval (Δt); receiving at least one lung image of at least one lung of the patient, the at least one lung image being timestamped with an image acquisition time (timg,actual); and at least one of: (i) displaying the at least one lung image; and/or (ii) analyzing the at least one lung image to generate a proning recommendation for the patient, and displaying, on a display device, a representation of the proning recommendation.
