Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.

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.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient includes a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the respiratory gas is controlled by a microprocessor, a mixing area for mixing a first gas and a second gas in the respiratory gas flow pathway, a humidification area downstream of the mixing area and configured for humidifying respiratory gas in the respiratory gas flow pathway, and a heated delivery conduit for minimizing condensation of humidified respiratory gas.

A ventilator system is capable of displaying complex information patterns in a GUI, thereby allowing a clinician to get subtract complex information from multiple parameters inputs.

Systems, and methods relate to a medical device receiving a treatment parameter operating point within a first operating region defined by a first set of operating points for which automatic incremental adjustment of a parameter in the current operation is permitted. In an illustrative example, incremental adjustment may use artificial intelligence based on patient feedback and sensor measurement of outcomes. Some exemplary devices may receive a request to alter the current treatment parameter operating point to a second treatment parameter operating point outside the first operating region and in a second operating region in a known safe operation zone, bounded by a known unsafe zone unavailable to the user. In the second operating region, some examples may restrict the step size of incremental adjustments requested by the user. Data may be collected for cloud-based analysis, for example, to facilitate discovery of more effective treatment protocols.

A respiratory device comprising a housing enclosing a chamber and an orientation indicator moveable with respect to the housing between a first position indicative of an orientation of the housing predetermined to be suitable for operation of the respiratory device, and a second position indicative of an orientation of the respiratory device predetermined to be less suitable for operation of the respiratory device. The orientation indicator is positioned in a location on the respiratory device visible to a user during the operation of the respiratory device.

A feedback providing facial mask is provided. The mask includes a facial adaptive component including a deformable member embedded in an interior region of the facial adaptive component and circuits, each of the circuits being operable in an open-circuit state or a closed-circuit state. The mask also includes a battery, light elements coupled to the battery and positioned within the deformable member, and sensors positioned at a plurality of locations within the deformable member. The sensors are connected to one of the light elements, wherein each of the circuits include the battery, one of the light elements, and at least one of the plurality of sensors, and wherein one or more of the circuits change from operating in the open-circuit state to the closed-circuit state in response o the one or more of the sensors contacting skin on an object that is external to the mask.

Disclosed is an NO delivery device for supplying an NO-containing gas, including an NO injection line, a flow rate measurement device and a valve device. The valve device is normally closed. An emergency line connected to the injection line includes an emergency solenoid valve, which is normally open, and a flow rate control device. An operating unit operates these elements. In the event of malfunction of the operating unit, the emergency solenoid valve passes to an open position, whilst the valve device passes to a closed position. The flow rate control device supplies the gas at a pre-fixed emergency flow rate of gas, determined on the basis of the gas flow rate measurements supplied by the flow rate measurement device during the normal functioning of the device prior to the malfunction. Gas supply installation including such an NO delivery device and a medical ventilator.

A method of ventilating a patient controls an actuator, in accordance with a prescribed value for a respiratory parameter, to compress an inflatable bag to cause air to flow out of an output valve of the bag. The respiratory parameter may include tidal volume, pressure, volume limit, peak pressure, I:E ratio, inspiratory time, and/or breathing rate of the air flowing through the output valve. The method also senses the pressure flowing through the output valve, and sends a pressure signal to the controller. Additionally, the method senses the flow rate through the output valve, and sends a flow rate signal to the controller. The method also adjusts the compression of the actuator as a function of the flow rate signal and/or the pressure signal to adjust the output tidal volume, pressure, volume limit, peak pressure, I:E ratio, inspiratory time, and/or breathing rate to be in accordance with the prescribed value.

A portable medical triage kit and interactive application that leads a user through a medically acceptable triage protocol for treating medical emergencies. The interactive application leads the user to treat major life threats of all nearby victims before treating minor threats of anyone.
