Disclosed embodiments of an endotracheal tube (ETT) guard system help to hinder self-extubation of the ETT of an awake patient who may reflexively attempt removal, but also allow early mobilization and exercise necessary for preservation of muscle strength. Embodiments may include an ETT holder, which may be generic ETT holders offered by various medical device companies, or a specially configured ETT holder as described herein. Embodiments also may include a sensor that alarms when the ETT guard is moved beyond pre-set motion thresholds.

An apparatus for treatment of a respiratory condition, the apparatus comprising: a pressure generator configured to generate a flow of breathable gas; an intermediate component pneumatically connected to an air delivery tube, the intermediate component comprising a port configured to facilitate propagation of sound outside of the intermediate component; a sensor attached externally to the intermediate component and located adjacent to the port of the intermediate component, the sensor configured to sense sound propagated through the air delivery tube; and a controller. The controller can be configured to: receive a sound signal generated by the sensor as a result of sensing sound during operation of the apparatus, analyse the received sound signal, and effect a response based at least in part on the analysing.

A processor acquires a first radiographic image and a second radiographic image obtained by irradiating a subject, into which a tracheal tube has been inserted, with radiation in different directions, derives a three-dimensional position of a distal end of the tracheal tube in the subject on the basis of a position of the distal end of the tracheal tube in each of the first radiographic image and the second radiographic image, derives a three-dimensional position of a bronchial bifurcation in the subject on the basis of a bronchial bifurcation position in each of the first radiographic image and the second radiographic image, and determines insertion of the tracheal tube into an esophagus on the basis of the three-dimensional position of the distal end of the tracheal tube and the three-dimensional position of the bronchial bifurcation.

An apparatus, method and system for delivering CO.sub.2 into an inspiratory gas stream to formulate a blended respiratory gas in a manner that continuously maintains a target CO.sub.2 concentration in a volume of the inspired respiratory gas, for example, over the course of a breath or a volumetrically definable part thereof or a series of partial or full breaths.

A method of estimating a parameter indicative of respiratory flow of a patient being administered flow therapy, comprising: optionally administering a gas at a flow rate to the patient using a flow therapy apparatus with a patient interface, determining a terminal pressure in, at or proximate the outlet of the patient interface or in, at or proximate the nares of the patient, determining nasal RTF, determining a nasal flow parameter being or indicative of nasal flow based on the pressure and a nasal RTF, and optionally outputting the nasal flow parameter or parameter derived therefrom.

Systems and methods for managing the power consumption of an oxygen concentrator are disclosed. An oxygen concentration system may comprise a compression system, a canister system, one or more processors, and at least one of a pressure sensor or a movement sensor. The one or more processors may be configured to transition the oxygen concentration system to at least one of a prescribed mode of operation or a standby mode of operation. The timing of the transition may be based on at least one of a number of breaths detected from the pressure signals generated by the pressure sensor or an estimated energy content of the movement signal generated by the movement sensor. A predetermined volume or concentration of oxygen enriched air may be supplied to a user during the prescribed mode of operation. A reduced power may be provided to the compression system during the standby mode of operation.

Systems and methods are provided herein for remotely controlling a life-critical medical device. In one example, a system includes a life-critical medical device communicatively coupled to a remote device and configured to supply a medical therapy to a patient, the life-critical medical device including a display and memory storing instructions executable to output, to the display, a graphical user interface (GUI) that displays a plurality of real-time machine settings of the life-critical medical device, responsive to a first user input, display, via the GUI, a remote control panel including a session code usable to authenticate the remote device, and responsive to receiving an indication from an access server that the remote device has been authenticated, display, on the GUI, a notification indicating that the life-critical medical device is currently controlled by the remote device.

Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user. The device may suggest a corrective action based on the type of off-target ventilation detected. The device may also continuously analyze ventilation to determine changes in lung compliance over time and to identify pathological changes over time. The device may work within a network of devices and user interfaces via wired or wireless communication, and is not restricted to or dependent on the type of ventilatory device with which a patient is being supported.

A ventilation management system stores an initial configuration profile including a set of operating parameters for operating one or more respective ventilation devices. The system receives first ventilator data from a first ventilation device at a first location, and second ventilator data from a second ventilation device at a second location, the first and second ventilation devices being configured to operate based on the initial configuration profile, wherein the received first ventilator data comprises one or more current operating parameters of the first ventilation device, or physiological data obtained from a patient associated with the first ventilation device. The system modifies the initial configuration profile for use by the first ventilation device based on the received first ventilation data and provides the modified configuration profile to the first ventilation device. The modified configuration profile is implemented by the first ventilation device when approved by a clinician or the patient.

A dispensing device for dispensing anesthetic in a breathing gas stream includes a flow duct (42) for an anesthetic-containing breathing gas stream, a control unit (5) and a first temperature sensor (54). An anesthetic feed device (45) has an evaporation surface (46) arranged in the flow duct (42). The first temperature sensor (54) detects the temperature of the evaporation surface (46) and sends a first temperature signal (T1) to the control unit (5). A second temperature sensor (53) detects the temperature of the breathing gas stream in the flow duct (42) and sends a second temperature signal (T2) to the control unit (5). The control unit (5) is configured to determine an anesthetic concentration based on the first and second temperature signals (T1, T2).
