A respiratory device, such as a ventilator, for use in treating respiratory disorders and for preventing respiratory disorders. The respiratory device is configured to be powered from a range of different power sources including an internal battery, an external battery, AC power source or a DC power source. The device may be electrically connectable to a plurality of external batteries in a series and the power from each external battery is used sequentially along the series. A controller of the respiratory device is configured to detect the connection of the different power sources and control use of the different power sources using a power priority scheme. The controller may determine an estimate of the total available battery capacity from all the electrically connected batteries and display the total battery capacity on a user interface display of the device.

A method of providing pressure support to a patient that includes determining a measure associated with an inspiratory time of the patient during therapy, delivering a flow of breathing gas to the patient at an inspiratory positive airway pressure (IPAP) level during at least a portion of an inspiratory phase of the patient, delivering the flow of breathing gas to the patient at an expiratory positive airway pressure (EPAP) level that is less than the IPAP level during at least a portion of an expiratory phase of the patient, and automatically setting a rise time associated with a transition from the EPAP level to the IPAP level based on the measure associated with the inspiratory time of the patient. Also provided is a pressure support system adapted to perform the method.

The present disclosure provides systems and method for electric plasma synthesis of nitric oxide. In particular, the present disclosure provides a nitric oxide (NO) generation system configured to produce a controllable output of therapeutic NO gas at the point of care.

Systems, methods, and devices for facilitating insertion of an endotracheal tube and/or for verifying the position of the endotracheal tube within an airway of a patient with respect to an anatomical landmark of a patient are disclosed. Systems, methods, and devices for facilitating removal of debris from the distal airways of a patient under direct visualization are also disclosed.

The invention relates to a respiratory system comprising a first patient interface for delivery of a first flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device and/or sensing arrangement that is configure to facilitate a switching of the system between a first respiratory mode where the device allowing delivery of the first flow of gases to an outlet of the first patient interface when the second patient interface is absent from the patient, and a second respiratory mode where the device reducing or stopping delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.

The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermister 23), of gases flowing through a heated tube (3), supplying gases to a patient, which utilises the heating wire (21, 28) within the tube.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

A method of a control system controls an inductance motor in a device that may include an impeller using a pressure compensation control system. The control system may be implemented in a respiratory pressure therapy device. The control system may include a sensor configured to provide a pressure signal indicative of the pressure of a flow of fluid produced by the device. A measured pressure may be compared to a set pressure to determine a pressure error. A slip frequency may be adjusted as a function of the pressure error in an attempt to eliminate or minimise the pressure error.

A humidifier system for humidifying a microenvironment in a neonatal incubator includes a reservoir configured to hold water to be evaporated for humidifying the microenvironment. A chamber divider defines a heating chamber within the reservoir, and a movable heating element is positioned at a surface level of the water inside the heating chamber so as to heat the water at the surface level inside the heating chamber. The heating element is configured such that it is moved downward within the heating chamber so as to maintain the heating element at the surface level of the water as an amount of water in the reservoir decreases.

A nasal delivery device can include a nasal prong and an activation member. The nasal prong can have an opening at a top and bottom portion of the prong to allow for the passage of an aerosolized treatment agent through the nasal prong. The activation member can be positioned on the nasal delivery device at a location that is spaced apart from the subject's oral cavity when the nasal prong is received into the nostril of the subject. The activation member can detect a desired exhalation state of the subject and upon detection of the desired exhalation state, the activation member activates the delivery of the aerosolized treatment agent.
