An apparatus for humidifying a flow of pressurised, breathable air includes varying a first pressure of the flow of breathable gas to vary a level of thermal engagement between the conductive portion of the reservoir and the heater plate, varying a height of the variable portion varies a level of thermal engagement between the conductive portion of the reservoir and the heater plate, use of a humidifier reservoir base component with a maximum water capacity substantially equal to the predetermined maximum volume of water of the humidifier reservoir or the use of intersecting inlet and outlet axes.

A medical ventilation monitoring system is provided. The system includes: a patient ventilation unit defining an airflow path, and arranged so that when the unit is applied to a patient, the airflow path is in fluid communication with the patient's airway. The patient ventilation unit includes: an airflow sensor positioned to sense the presence of ventilation airflow to or from the patient and a communication link. The system also includes at least one processor arranged to communicate with the ventilation unit by the communication link. The at least one processor is configured to: provide an initial treatment protocol for providing care to the patient, receive data regarding a current condition of the patient from the ventilation unit, and determine an updated treatment protocol. The updated treatment protocol includes applying ventilation at an updated ventilation volume or at an updated ventilation rate based on information from the airflow sensor.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethysmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

In a method and system of regulating multiple anesthetic agents in a breathing circuit of an anesthetic breathing apparatus is disclosed, a primary anesthetic agent added to the breathing circuit is regulated to a set desired value of the amount of the primary anesthetic agent, and a secondary anesthetic agent in the breathing circuit is regulated to an amount of said secondary anesthetic agent that it is equal to or less than a defined threshold level, e.g. of the concentration, of the secondary anesthetic agent.

An inhalation monitoring system includes an inhaler having a medicament delivery apparatus configured to deliver medicament to a user during an inhalation of the user; inhalation monitoring apparatus, configured to, during the inhalation, gather data for determining a measure of the user's lung function and/or lung health; and a processor configured to receive the data from the inhalation monitoring apparatus and, using the data, determine a measure of the user's lung function and/or lung health.

A humidification chamber (24, 50, 300, 400, 500, 600 or 700) for humidifying gases is provided comprising: a water tub that is configured to receive a volume of water; a gases inlet for receiving a flow of gases into an interior volume of the humidification chamber; and a gases outlet through which a humidified flow of gases may exit the interior volume of the humidification chamber. One or more fill apertures (120) are provided in fluid communication with the water tub such that the water tub can be filled with water through the one or more fill apertures. A sealing closure (850) is also provided and configured to be releaseably mounted on the humidification chamber (24, 50, 300, 400, 500, 600 or 700), the sealing closure (850) being configured to sealingly close each fill aperture (120) when the sealing closure (850) is mounted on the humidification chamber to resist gas and/or vapour escaping from the one or more fill apertures (120).

Condensation or “rain-out” is a problem in breathing circuits and especially neonatal breathing circuits. The subject patent provides an improved breathing tube component for managing rain-out particularly in neonatal applications. In particular the breathing tube has a smooth inner bore, and an outer insulating layer containing stagnant gas and a heater wire.

The present invention is generally related to an apparatus and method for sanitizing a continuous positive airway pressure (CPAP) device, in particular the invention relates to a system, method and device that attach to a CPAP device and sanitizes all of the parts of the CPAP device, including the inner areas of the hose, reservoir and face mask most prone for bacteria buildup. The device has an ozone operating system and one or more ozone distribution lines that distributes ozone to a CPAP device and a non-permeable bag for sanitizing a CPAP mask.

A gas delivery component of a CPAP system is configured to magnetically connect to a second gas delivery component of the CPAP system to deliver a pressurized flow of breathable gas to a patient's airways. The gas delivery component includes a lumen forming a first part of a gas flow path for the breathable gas. A connection end of the gas delivery component is configured to engage the second gas delivery component. In addition, a magnetic connection assembly is located at the connection end and includes a magnet positioned at least partially within the lumen. The magnetic connection assembly is configured to magnetically secure the gas delivery component to the second gas delivery component.

A medical system includes a manual patient ventilation unit defining an airflow path arranged so that when the unit is applied to a patient the airflow path is in fluid communication with the patient's airway. The patient ventilation unit includes a ventilation bag configured to enable manual ventilation of the patient by a rescuer, an airflow sensor in the airflow path positioned to sense the presence of ventilation airflow and measure a gas flow rate in the airflow path, and a pressure sensor in the airflow path positioned to sense gas pressure in the airflow path. The system also includes a processor arranged to receive data generated by the airflow sensor and the pressure sensor and determine one or more ventilation quality parameters based at least in part on a gas flow volume calculated based on the sensed gas flow rate and gas pressures.
