The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

A ventilator including a housing; a gas inlet port disposed in the housing and adapted to be coupled to a gas source to receive a flow of gas; a valve assembly coupled with the gas inlet port for controlling flow of gas from the gas inlet port to a gas outlet port disposed in the housing and adapted for being coupled to a patient interface to fluidly couple the gas outlet port to the airway of a patient; a controller module disposed in the housing, the controller module comprising a controller operatively coupled with the valve assembly to control operation of the valve assembly; an airway pressure sensor positioned between the valve assembly and the patient interface to measure air flow output into flowing into the airway of the patient; wherein the pressure sensor is operatively connected to the controller module to control the operation of the valve assembly in response to changes in air flow output measured by the airway pressure sensor during use.

A patient interface is disclosed that includes: a plenum chamber pressurisable to a therapeutic pressure; a seal-forming structure joined to the plenum chamber and comprising a nasal portion, an oral portion, and at least one hole configured to deliver a flow of air at said therapeutic pressure to at least the patients nares in use, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout the patients respiratory cycle in use; a vent comprising a plurality of holes configured to allow a continuous vent flow from an interior of the plenum chamber to ambient; a positioning and stabilising structure comprising at least one tie and being configured to hold the seal-forming structure in a therapeutically effective position on the patient's head in use; and a textile portion configured to contact the patients face.

The present disclosure relates to a system and method for use of acoustic reflectometry information in ventilation devices. The system and method includes a speaker to emit sound waves into an intubated endotracheal tube (“ETT”) and a microphone to detect returning acoustic reflections. In addition, the system and method includes a reflectometry device in communication with a ventilation device for analyzing timings and amplitudes of the returning acoustic reflections to determine a size of a passageway around an ETT tip, location and size of ETT obstructions, and relative movement of the ETT tip within a trachea. The reflectometry device is also configured to determine a resistance parameter representative of resistance to actual flow of air through the ETT based upon a function of the diameter of the ETT, length of the ETT, and percent obstruction of the ETT, where the resistance parameter is used to calculate the tracheal pressure.

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 includes electronic control circuitry configured to control a supply of breathing gas for a plurality of respiratory cycles, measure a volume received by the patient in each of the plurality of respiratory cycles, and determine, for each cycle of the plurality of respiratory cycles, a cycle score corresponding to a deviation between the volume of the cycle and a predetermined target volume. The determined cycle score can be selected from a predetermined number of cycle scores that span positive and negative numbers based on the deviation. A pressure step value can be determined based on a plurality of cycle scores corresponding to the plurality of respiratory cycles, and a current pressure of the breathing gas is adjusted by an amount corresponding to the determined pressure step value. The pressure step value may be generated by dividing a sum of the plurality of cycle scores by a sample size.

A diagnostic device is disclosed for characterisation of particles from a patient's airways, such as a lung, when ventilated by a ventilator, and/or for control thereof, comprising a particle detecting unit configured to be connected to a conduit for passing expiration fluid from said patient, for obtaining data related to particles being exhaled from said patient's airways.

An aerosol medicament delivery adapter comprises a first conduit, second conduit and a diverter element. The first conduit encloses a flow path chamber and extends between an upstream first end and a downstream second end. The second conduit comprises an aerosol medicament delivery conduit that includes an upstream first end adapted to be fluidly coupled to a particle generator, and a downstream second end luidly coupled to the first conduit at a Y-junction proximate the upstream first end of the first conduit. The diverter element comprises a flow diverter chamber disposed within the first conduit or the second conduit. The cylindrical flow diverter chamber includes a transitional flow cross-section and a principal axis, extending between a first end and a second end thereof. The diverter element creates flow eddies for enhancing an entrainment of aerosol particles, delivered via the second conduit, within a pressurized gas flow along the flow path within the first conduit.

In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.
