A capnography system includes a CO.sub.2 sensing system having a CO.sub.2 sensor configured to measure a CO.sub.2 concentration in exhaled breath of a subject, a processor configured to derive one or more breath related parameters based on the measured CO.sub.2 concentration, and a communication unit. The capnography system includes a tubing system configured to allow flow of respiratory gasses therethrough. The tubing system includes a connector configured to connect the tubing system to the CO.sub.2 sensing system and a communication component configured to provide an indication of a type of the tubing system to the communication unit. The communication unit is configured to transfer data to the processor based on the indication obtained from the communication component, and the processor is configured to change or suggest a change of an operation mode of the CO.sub.2 sensing system based on the data.

Described are systems for beds that can include sensors for sensing physical phenomena in an environment surrounding a bed, a display for outputting information about the environment, the bed, and a sleeper, and a controller communicably coupled to the sensors. The controller can receive the sensed physical phenomena from the sensors, analyze the physical phenomena to determine at least one of environmental, sleep, and health metrics of a sleeper in the bed, and determine, based on at least one of the environmental, sleep, and health metrics of the sleeper, control signals to modify the environment surrounding the bed. The controller can also output, at the display, the environmental, sleep, and health metrics of the sleeper. The controller can also transmit the control signals to a second controller in order to engage a home automation device. The physical phenomena can include ambient sound, ambient light, ambient CO2 concentration, and/or ambient temperature.

The invention discloses a noninvasive spontaneous respiratory monitoring device, which comprises a sensing patch that can be placed in proximity to the nasal airway of a patient. The sensing patch measures both the flow profile and carbon dioxide concentration of a patient and wirelessly transmits the acquired data to the control circuitry for synchronizing the respiratory support of a mechanical ventilator. The device can also be used as a standalone unit for monitoring for the diagnosis purposes the spontaneous respiratory function of a patient with respiratory dysfunction.

Provided herein is a capnography fitting for use in a capnography system wherein the capnography fitting is configured to fit inhalation masks of various sizes and shapes so that viable carbon dioxide readings can be obtained from an air sample obtained from a patient's exhaled gas. The fitting includes a rigid tube having a proximal end inlet configured to receive an inhalation gas and to slidably engage a mixed gas fitting, and a distal end outlet configured to slidably engage directly to an inlet of an inhalation mask configured to cover a nose and/or mouth. The tube also includes an angled port in fluid communication with and disposed adjacent to the proximal end inlet or the distal end outlet. Methods and kits are also provided.

Semi-autonomous vehicle apparatus which is controlled by a plurality of control sources includes a vehicle which may function autonomously and apparatus for control of the vehicle by either an onboard driver or a driver not situated onboard. The vehicle may also be controlled by an off-vehicle computational device. Hierarchy setting apparatus determines which one or combination of the possible control entities take priority. Persons using the apparatus are identified by either a password or, preferably by providing identification based on a biologic feature. Management of impaired vehicle operators is provided for.

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.

Methods of and devices for detecting a measurable characteristic of the gas sample. The methods and devices are able to detect a value of or a change of measurable characteristic (e.g., such as chemical concentrations), a change of chemical compositions and/or biological responses of a living organism that are induced by a stressor. The biological responses are able to include cellular stress, damage, and immune responses. The stressor is able to include an exposure to ionizing radiation. The effects of the stressors are able to be monitored in terms of changes in the chemical concentrations and chemical compositions in an exhaled breath. The chemicals are able to function as bio-markers. The chemicals that are to be monitored are able to include nitric oxide, carbon monoxide, carbon dioxide, ethane, and other molecules related to specific disease resulting from the stressor.

Certain exemplary embodiments can provide a system, machine, device, manufacture, circuit, composition of matter, and/or user interface adapted for and/or resulting from, and/or a method and/or machine-readable medium comprising machine-implementable instructions for, activities that can comprise and/or relate to, facilitating determination of the oxygen consumption, carbon dioxide production, respiratory exchange ratio, and/or energy expenditure of a mammal.

Disclosed herein are facially fitting devices, such as nasal cannulas and oxygen masks, including illuminating placement marker(s), which facilitate correct placement of the facially fitting devices on a face of a subject in dark conditions. The placement marker is powered by a thermo-electric generator, which generates electrical power via thermal coupling thereof to skin on the face of a subject when the facially fitting device is fitted, or partially fitted, on the face of the subject.

The disclosed systems and methods provide a printed electronics breath indicator that may be directly printed or molded onto a manufactured breathing device, or separately attached to an existing breathing device. The printed electronics breath indicator may include an electroluminescent indicator, a sensor, and a processor. The processor may be configured to receive sensor data from the sensor, the sensor data including detected carbon dioxide (CO2) or oxygen (O2) levels. The processor may be further configured to determine a current breathing state of the patient based on the received sensor data. The processor may be further configured to cause the electroluminescent indicator to generate a visual representation according to the determined current breathing state of the patient. The visual representation may comprise a variable visual representation that displays one or more visual parameters that are proportional to the detected CO2 or O2 levels.
