Lung protective ventilation control
A method of ventilator control that includes receiving machine data from a mechanical ventilator and detecting one or more clinical events in the received machine data. The method further includes evaluating the machine data within the detected one or more clinical events for compliance with lung protective ventilation (LPV) recommendations. The method further includes at least one of producing a visual indication or a graphical display of the evaluated compliance with the LPV recommendations and controlling the mechanical ventilator based on the evaluated compliance with the LPV recommendations.
Administration and monitoring of nitric oxide in ex vivo fluids
Described are systems and methods for monitoring administration of nitric oxide (NO) to ex vivo fluids. Examples of such fluids include blood in extracorporeal membrane oxygenation (ECMO) circuits or perfusion fluids used for preserving ex vivo organs prior to transplanting in a recipient. The systems and methods described herein provide for administering nitric oxide to the fluid, monitoring nitric oxide or a nitric oxide marker in the fluid, and adjusting the nitric oxide administration.
AIRWAY ADAPTER
An airway adapter forms a part of a breathing circuit that is connected to a test subject. A first cylindrical portion forms a male terminal that is fitted into a female member forming another part of the breathing circuit. A second cylindrical portion forms a female terminal that compartmentalizes a fitting portion into which a male member forming another part of the breathing circuit is fitted. An airway forming portion is disposed in an internal space compartmentalized by the first cylindrical portion, and forms an airway communicating with the fitting portion. A first sealing member is disposed on an outer circumferential surface of the first cylindrical portion and has higher flexibility than the first cylindrical portion.
COMPENSATING FOR DISRUPTIONS IN BREATHING GAS FLOW MEASUREMENT
The present disclosure generally relates to systems and methods for delivery of therapeutic gas to patients, using techniques to compensate for disruptions in breathing gas flow measurement, such as when breathing gas flow measurement is unavailable or unreliable. Such techniques include using historical breathing gas flow rate data, such as moving average flow rates, moving median flow rates and/or flow waveforms. At least some of these techniques can be used to ensure that interruption in therapeutic gas delivery is minimized or eliminated.
AN AEROSOL-GENERATING SYSTEM COMPRISING A HEALTH MONITORING DEVICE
An aerosol-generating system is provided, including: a health monitoring device including a sensor to collect health data from a user, a controller to receive the health data and determine a health parameter based on the data, and a health monitoring device power supply to supply electrical power to the controller and the sensor, the device not being an aerosol generator; an aerosol-generating device including a cavity to receive a plug of tobacco, an aerosol-generator to generate aerosol from the plug, and an aerosol-generating device power supply configured to supply electrical power to the aerosol-generator; and a charger including a cavity to receive the health monitoring and aerosol generating devices, and a charger power supply to transfer electrical power to the health monitoring device power supply, and from the charging unit power supply to the aerosol-generating device power supply, the cavity being a single cavity.

Apparatus and method for filtering liquid particles from inspiratory gas flow of a patient breathing circuit affiliated with a ventilator and/or nitric oxide delivery system
The present disclosure relates to a filter apparatus for filtering liquid from a gas, the apparatus having a first housing having a gas inlet and a gas outlet; a first filter media disposed in the first housing; a second filter media disposed in the housing; and a second housing forming a first collection basin disposed in the flow path between the first filter media and the second filter media, so that a path is defined for the gas flowing from the inlet, through the first filter media, past the collection basin, through the second filter media, and to the outlet. The present disclosure also relates to a method of passing a gas through a coalescing filter media and through a hydrophobic filter media.
Composite ionomer membrane tubing modules and system and methods incorporating same
A composite ion conducting tube is made by wrapping a support material or ion conducting sheet to from a tube having overlaps of layers that are bonded. The ion conducting sheet or tape used to make the tube may be very thin and the tube may be formed in situ by wrapping the support material and then coating with ion conducting polymer. The ion conducting tubes may be used in a pervaporation module or desalination system. The ion conducting tubes may be spirally wrapped or longitudinally wrapped and may be very thin having a tube wall thickness of no more than 25 microns.
Ventilator system with multiple airflow control lumens
Ventilator system with multiple inspiratory lumens is provided. The inspiratory lumens are configured so that separate inspiratory lumens provide inspiratory gas mixtures to separate portions of a patient's airways, for instance to separate lungs and/or bronchi. The ventilator system can include one or more expiratory lumens to evacuate expiratory gases from airways. The use of separate inspiratory lumen(s), with expiratory lumen(s), allows for functional separation of structural portions of the lungs, and maintenance of continuous or almost continuous flow through at least part of respiratory cycle via inspiratory and expiratory lumens. This can further reduce dead space and clear suspended therein diseases causative agents with improvement in outcomes, reduce risk of cross-contamination or cross-infection between different parts of airways, for example such as cross-infection from one lung lobe to another lobe or. The ventilator system allows for independent titration of PEEP, pCO.sub.2 and pO.sub.2 with no need for permissive hypercapnia.
