  • Patent number: 10842443
    Abstract: This disclosure describes systems and methods for monitoring and evaluating data associated with ventilatory parameters to detect expiratory airflow limitation in a ventilated patient. For example, a ventilator may monitor flow and/or pressure during ventilation of the patient. Based on the flow and/or pressure measurements, or ventilatory data derived therefrom, the ventilator may calculate expiratory resistance. Moreover, the ventilator may trend expiratory resistance over time to produce an expiratory resistance waveform. In embodiments, the ventilator may calculate the slope of the expiratory resistance waveform during an initial part of exhalation. If the slope of the expiratory resistance waveform during the initial part of exhalation breaches a defined slope threshold, the ventilator may determine that the patient exhibits expiratory airflow limitation.

  • Patent number: 10813997
    Abstract: A system for the physical manipulation of free magnetic rotors in a circulatory system using a remotely placed magnetic field-generating stator is provided. In one embodiment, the invention relates to the control of magnetic particles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow. Examples of vascular occlusions targeted by the system include, but are not limited to, atherosclerotic plaques, including fibrous caps, fatty buildup, coronary occlusions, arterial stenosis, restenosis, vein thrombi, arterial thrombi, cerebral thrombi, embolisms, hemorrhages, other blood clots, and very small vessels.

  • Patent number: 10813598
    Abstract: This disclosure describes, among other features, systems and methods for using multiple physiological parameter inputs to determine multiparameter confidence in respiratory rate measurements. For example, a patient monitoring system can programmatically determine multiparameter confidence in respiratory rate measurements obtained from an acoustic sensor based at least partly on inputs obtained from other non-acoustic sensors or monitors. The patient monitoring system can output a multiparameter confidence indication reflective of the programmatically-determined multiparameter confidence. The multiparameter confidence indication can assist a clinician in determining whether or how to treat a patient based on the patient's respiratory rate.
