A first relation between pressure Pvent and volume Vassist and a second relation between pressure Pvent and volume Vvent are calculated. Using the first and second relations, a ratio is determined between pressure Pvent at volume Vvent and pressure Pvent at volume Vassist, with volume Vvent equal to volume Vassist, for a plurality of volumes Vvent and Vassist. Values of Pvent are multiplied by the corresponding calculated ratios to calculate a third relation between a predicted inspiratory pressure Ppred and volume Vassist.

    Abstract: An apparatus, system, and method for the measurement, aggregation and analysis of data collected using non-contact or minimally-contacting sensors provides quality of life parameters for individual subjects, particularly in the context of a controlled trial of interventions on human subjects (e.g., a clinical trial of a drug, or an evaluation of a consumer item such as a fragrance). In particular, non-contact or minimal-contact measurement of quality-of-life parameters such as sleep, stress, relaxation, drowsiness, temperature and emotional state of humans may be evaluated, together with automated sampling, storage, and transmission to a remote data analysis center. One component of the system is that the objective data is measured with as little disruption as possible to the normal behavior of the subject. The system can also support behavioral and pharmaceutical interventions aimed at improving quality of life.

  • Patent number: 10874797
    Abstract: A drug administration controller has a sensor that generates a sensor signal to a physiological measurement device, which measures a physiological parameter in response. A control output responsive to the physiological parameter or a metric derived from the physiological parameter causes a drug administration device to affect a treatment of a person, such as by initiating, pausing, halting or adjusting a dosage of drugs administered to the person.

  • Patent number: 10869977
    Abstract: In one embodiment, a method for accurate leak estimation in a flow generation system includes measuring a total flow through the flow generation system, measuring a pressure in the primary flow circuit of the flow generation system, determining when the measured pressure is within a predetermined threshold of EPAP, and calculating an intentional leak flowrate and an unintentional leak flowrate based on the relationship QFS(t)=QIL(t)+QUL(t) when the measured pressure is within the predetermined threshold. In another embodiment, a flow generation system includes in one embodiment an airflow generator connected in-line to a flow sensor, a pressure sensor and a patient interface connection by a first gas flow circuit, and a controller electrically coupled to the airflow generator, the flow sensor and the pressure sensor.

  • Patent number: 10859456
    Abstract: A ventilator is configured to assist a user with breathing, while eliminating the need for extraneous sensors and tubing normally found in prior art ventilators. The ventilator relies on a predetermined relationship between a measurable quantity associated with a compressed gas and the maximum pressure of that compressed gas upon delivery to the user. The measurable quantity may be mass flow rate of the compressed gas or pressure within a delivery lumen used to transport the compressed gas, among others. Based on the predetermined relationship, the control logic within the ventilator determines whether the pressure of compressed gas delivered to the user exceeds a maximum allowable pressure. When the maximum pressure is exceeded, the control logic initiates corrective action to reduce the pressure of the compressed gas.

  • Patent number: 10850054
    Abstract: Methods and apparatus provide automated controls for a respiratory pressure therapy device, such as a servo-ventilator. For example, a controller of a respiratory pressure therapy device may control application of pressure support ventilation therapy to an airway of a patient. The controller may control the respiratory pressure therapy device to auto-titrate an expiratory positive airway pressure (EPAP) of a pressure support ventilation therapy so as to maintain airway patency of the patient. The EPAP may be bounded below by a floor pressure limit. The controller may control the respiratory pressure therapy device to repeatedly adjust the floor pressure limit depending on events of interest during the auto-titration of the EPAP. Such methodologies may improve treatment for patients such as those suffering from sleep disordered breathing-comorbid hyperarousal disorders.

  • Patent number: 10835699
    Abstract: A mechanical ventilator (10) is connected with a ventilated patient (12) to provide ventilation in accordance with ventilator settings of the mechanical ventilator. Physiological values (variables) are acquired for the ventilated patient using physiological sensors (32). A ventilated patient cardiopulmonary (CP) model (40) is fitted to the acquired physiological variables values to generate a fitted ventilated patient CP model by fine-tuning its parameters (50). Updated ventilator settings are determined by adjusting model ventilator settings of the fitted ventilated patient CP model to minimize a cost function (60). The updated ventilator settings may be displayed on a display component (22) as recommended ventilator settings for the ventilated patient, or the ventilator settings of the mechanical ventilator may be automatically changed to the updated ventilator settings so as to automatically control the mechanical ventilator.

  • Patent number: 10814081
    Abstract: The present disclosure pertains to a method and system configured for detecting a gas delivery malfunction in a spontaneous mechanical ventilation mode. In some embodiments, the system comprises a pressure generator, a subject interface, one or more sensors, one or more processors, electronic storage, a user interface, and/or other components. The detection of a gas delivery malfunction in a spontaneous mechanical ventilation mode is implemented by generating a test flow of gas for delivery to an airway of a subject, and monitoring a responsive flow of gas in the subject interface. If one or more parameters associated with the responsive flow of gas demonstrate inconsistencies with a reference flow of gas responsive to the test flow under a condition that there is no gas delivery malfunction, the system determines that there is a gas delivery malfunction.

  • Patent number: 10773039
    Abstract: A system and a method for expiratory flow limitation (EFL) detection by controlling positive pressure (e.g., PEEP) applied during expiration for a subject is based on a temporary perturbation or adjustment of a pressure level of positive pressure during exhalation on selected breaths. The different responses to such a perturbation of flow-limited breaths compared to non-flow limited breaths is used to assess EFL in a subject. Automatic adjustments of the positive pressure applied to the patient are used in the disclosed algorithm to abolish EFL, and are implemented through existing ventilators and other respiratory devices.

  • Patent number: 10765359
    Abstract: Sensing circuitry of an implantable medical device (IMD) system may sense a cardiac signal that varies according to a cardiac cycle of a patient. Processing circuitry of the IMD system may determine a series of consecutive cardiac cycle length metric values based on the sensed cardiac signal, identify a plurality of pairs of the cardiac cycle length metrics, each of the pairs of cardiac cycle length metrics separated by an integer ‘n’ of the cardiac cycle length metrics, and construct a distribution of the pairs of cardiac cycle length metrics based on values of the cardiac cycle length metrics for each of the pairs. The processing circuitry may detect a sleep apnea episode of the patient based on one or more characteristics of the constructed distribution, and control communication circuitry of the IMD system to transmit an indication of the detected sleep apnea episode to the external computing device.
