An apparatus and method for collecting a breath sample are provided. The apparatus has a breath input interface configured to receive exhaled breath, a container connected to the breath input interface for receiving at least some of the exhaled breath, the container having a cavity with a volume that is controllable, and at least one controller configured to control the volume of the cavity to increase at a volume increase rate that is at most equal to a flow rate of the exhaled breath received by the breath input interface.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a wearable biometric sensor system including a flow rate sensor, a carbon dioxide sensor, a housing configured to retain the flow rate sensor and the carbon dioxide sensor and align the flow rate sensor and carbon dioxide sensor with respect to an air flow path when the housing is affixed to a wearable device, and a control unit in data communication with the flow rate sensor and carbon dioxide sensor.

A system for managing an alarm issued by a medical device being used to treat a patient is disclosed. The system includes a processor coupled to at least one of the medical device, a monitoring system being used to monitor the patient, and a hospital system. The system also includes a memory coupled to the processor. The memory contains data and instructions that, when loaded into the processor and executed, cause the processor to receive the alarm and retrieve information from one or more of the medical device, the monitoring system, and the hospital system. The information comprises a dynamic attribute associated with the patient. The system then assigns a sub-priority to the alarm based in part on evaluation of the dynamic attribute and provides an alert to a staff member.

Systems and methods for measurement of end tidal carbon dioxide, including a device having a body and a tubular gas line. The body is adapted to be attached to a patient airway and has a first gas line securing portion which has an aperture through it and is adapted to secure the gas line to the body. The tubular gas line is secured in the aperture. The tubular gas line has a proximal portion extending from a proximal end of the aperture and has a proximal end which is adapted to be connected to an end tidal CO2 monitor. The tubular gas line also has a distal portion extending from a distal end of the aperture and having a distal end which provides an inlet for end tidal CO2 exhaled by a patient.

A method and a device for measuring the content of at least one gas in exhaled air and to a device for ventilation. Due to the combination of a rapid respiratory phase sensor with a valve controllable depending on the detected respiratory phase, the use is made possible of a slower gas sensor to measure the content of a specific gas in the exhaled air during a certain period in the respiratory cycle so that the use of more economical and/or smaller and/or more accurate gas sensors is possible.

Device and method for determining an efficacy of chronic pain treatment including providing a first set of at least one stimulus to a subject, obtaining first measurements of at least two physiological parameters in response to the first set of at least one stimulus, providing chronic pain treatment to the subject, providing a second set of at least one stimulus to the subject, obtaining second measurements of the at least two physiological parameters in response to the second set of at least one stimulus; and determining an efficacy of the chronic pain treatment by applying a classification algorithm on the first and second measurements of the at least two physiological parameters.

Described herein is a method for providing real-time information about the cardiac and/or respiratory performance of an individual, comprising the steps of: a) subjecting the individual to a cardiopulmonary stress test suitable for detecting, over time, a respiratory rate and other cardiac or respiratory parameters of the individual; b) determining respective characteristic curves of the individual, with the respiratory rate as dependent variable and one of the other cardiac or respiratory parameters as independent variable; c) detecting, through a wearable device, the current respiratory rate of the individual; d) determining, based on the current respiratory rate of the individual and the characteristic curves obtained at step b), the other current cardiac or respiratory parameters of the individual; e) providing real-time information about the cardiac and/or respiratory performance of the individual on the basis of the other current cardiac or respiratory parameters determined at step d).

Disclosed herein include systems, devices, and methods for capturing compounds, such as volatile organic compounds, in gaseous samples onto capturing tubes, such as thermal desorption tubes, for subsequent analysis, such as disease diagnosis (e.g., cancer diagnosis).

A system and method for generating a metabolic dysfunction nourishment program comprises a computing device configured to obtain a metabolic component as a function of a user metabolic system, identify a metabolic panel as a function of the metabolic component, wherein identifying further comprises receiving a status grading, ascertaining a metabolic functional goal, and identifying the metabolic panel as a function of the status grading, metabolic functional goal, and metabolic component using a metabolic machine-learning model, determine an edible as a function of the metabolic panel, wherein determining further comprises receiving a nourishment composition from an edible directory, producing a nourishment demand as a function of the metabolic panel, and determining the edible as a function of the nourishment composition and nourishment demand using an edible machine-learning model, and generate a nourishment program as a function of the edible and a metabolic outcome using a nourishment machine-learning model.

Embodiments of the present invention include a system having at least one sensor configured to monitor a muscle oxygen saturation (SmO2) level of a patient who is undergoing cardiac arrest and to generate a signal representing SmO2 level; a user interface device; a processor communicably coupled to the user interface device, the processor configured to cause the user interface device to present an array of two or more possible nodes of a clinical decision support tree, wherein at least one of the nodes indicates cardiopulmonary resuscitation (CPR) treatment of the patient with no ventilation, and wherein at least another of the nodes indicates CPR treatment of the patient with active ventilation; determine which of the two or more possible nodes should be emphasized based on the SmO2 level; and update the array of the two or more possible nodes based on the determination.
