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.

A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modeled based on the transformed data set.

A patient interface may include a dual chamber cushion assembly having a nasal chamber and an oral chamber. The nasal chamber may be arranged to deliver pressurized breathable gas to a patients nasal passages, and the oral chamber may be arranged to deliver pressurized breathable gas to the patients oral passages. The nasal chamber may be pressurized to a different level than an oral chamber to promote nasal breathing. An air passage may fluidly connect the nasal chamber and the oral chamber so that pressurized breathable gas may flow from the nasal chamber to the oral chamber.

A process and a device determine an indicator of an intrinsic end-expiratory pressure in the lungs of a patient. Embodiments are based on the device, ventilator with the device, and the process using the device that includes an interface arrangement configured for an exchange of information with a ventilation device and a control unit that determines first information on a first breathing pressure generated by muscles of the patient, at a first time, at which an inhalation attempt of the patient is present and determines second information on a second breathing pressure generated by the muscles of the patient, at a second time, at which breathing gas flow towards the patient starts. The control unit further determines the indicator of the intrinsic end-expiratory pressure based on the first information and based on the second information.

A system for assessing extubation includes a respiratory assistance device, an artificial intelligence platform, and a hospital information system. The respiratory assistance device is adapted to communicate with a trachea of a patient. The artificial intelligence platform includes a prediction module. A method for assessing extubation includes the following steps. Measured values of respiratory parameters of the patient are recorded by the respiratory assistance device. The recorded times and the measured values of the respiratory parameters corresponding to each of the recording times are transmitted to the artificial intelligence platform. The prediction module analyzes the measured values of respiratory parameters within a predetermined time period according to a prediction model to generate a prediction result. The prediction result is transmitted to the hospital information system and is recorded into a medical record of the patient. With such design, a reference for extubation assessment that is more accurate is provided.

A respiratory device can include an oxygen generator and a ventilator. The oxygen generator can include a first inlet to ambient air, a vacuum or pressure swing oxygen generating system in fluid communication with the first inlet, a first fluid pathway, and a first outlet. The ventilator can include a second inlet to ambient air and a blower in fluid communication with the second inlet to draw ambient air. The ventilator can include a third inlet in fluid communication with the first fluid pathway upstream of the first outlet. The blower can also be in fluid communication with the second inlet to draw at least some of the extracted oxygen. The ventilator can also include a second outlet in fluid communication with the blower to dispense a mixture of the ambient air and the extracted oxygen to the user.

Described herein is a respiratory care apparatus capable of performing multitude of therapy for secretion management and breath assistance therapy. The respiratory care apparatus comprises an electromechanical air router assembly (EARA) and an interfacing assembly. The EARA includes independent first and second pressure generating sources for assisted inhalation/insufflation and assisted exhalation/exsufflation process. The interfacing assembly includes a patient interface port and a patient interface tube. The and negative pressure at the patient interface port for assisted inhalation/insufflation and assisted exhalation/exsufflation processes respectively. The assisted inhalation/insufflation and assisted exhalation/exsufflation processes are carried out independently through separate conduits/passages to reduce contamination and infection. Further, the respiratory care apparatus comprises a garment which oscillates due to alternate positive and negative pressure generation and provides therapy to the patient.

A respiratory treatment device includes a blower for providing flow of breathable gas to a patient and one or more accessory devices. The respiratory treatment device includes active power management to distribute power from a power source that does not have sufficient power to simultaneously power the blower and the accessory devices. The active power management prioritizes power to the blower and limits, based on current measurements of the blower and the accessory devices, the power supplied to the accessory devices to keep the sum of the power drawn at or below the capacity of the power supply. When additional power is available, due reduced power consumption of the blower, the power to one or more accessory devices is raised beyond a target in order to compensate for when power was not supplied to the one or more accessory devices.

A method for preventing or treating an arrhythmia including administering an effective amount of hydrogen to a patient in need thereof.

Monitors for evaluating airway procedures, particularly in a pre-hospital environment, are described herein. In an example method, an airway parameter of an individual receiving assisted ventilation is detected by an airway sensor. A monitor determines a metric based on the airway sensor. Further, the monitor performs an action based on the metric.
