Methods of inducing anesthesia in a subject by administering an effective amount of a compound or a mixture of compounds according to Formula I are provided. Compounds of Formula I are a class of halogenated alcohol derivatives with a vapor pressure of at least 0.1 atmospheres (76 mmHg) at 25° C. Compounds of Formula I can be administered by any route sufficient to achieve a desired anesthetic endpoint.

An anaesthetic halocarbon capture system is provided. The system includes a pressure-intolerant sleeve containing filter material for capturing one or more types of anaesthetic halocarbon prior to supercritical fluid extraction, and a pressure-tolerant housing into which the sleeve can be inserted so as to permit exposure of the sleeve contents to pressures required for supercritical fluid extraction.

The embodied invention is a new inspiration/expiration ventilator flow design, with a constant inspiration flow and intermittent-concurrent expiratory flow based on lung pressure setpoints. This mode is possible by using a new dual lumen tube inserted into a patient Trachea. Additionally, the control provides support for patient initiated breathing which is initiated by a lung pressure drop. This control provides continuous and gentle recruitment of lung alveoli.

An anesthetic vaporizer system includes a reservoir containing anesthetic agent, an agent level sensor measuring an agent level of the anesthetic agent in the reservoir, a display, and a controller. The controller is configured to receive agent level measurements from the agent level sensor over a time period, and determine the anesthetic agent is being added to the reservoir from an agent source based on the agent level measurements over the time period. A filling status is determined based on the agent level measurements and a filling status indicator is displayed based on the determined filling status.

The invention relates to a respiratory device (10) for the artificial respiration of a patient (12), comprising: —a respiration gas source assembly (15, 62), —a flow-changing device (16), —a humidifier device (38) which is designed to increase the value of the absolute humidity of the inspiratory respiration gas flow (AF), said humidifier device (38) having a liquid store (40) and an evaporation device (76) with a variable output for this purpose, —a respiration gas line assembly (30), —a proximal temperature sensor (48) which detects the temperature of the respiration gas flow (AF) in the proximal longitudinal end region (30a) of the respiration gas line assembly (30), —a humidity sensor assembly (66) which directly or indirectly detects the absolute humidity of the inspiratory respiration gas flow (AF), —a flow sensor (44), and —a controller (18) which is designed to control the operational output of the evaporation device (76)

Various methods and systems are provided for determining a quality of a medical gas flow. In one example, a method for a medical gas quality monitoring system includes obtaining measurements of a medical gas via a plurality of sensors, the plurality of sensors including at least one of a humidity sensor, a particulate matter sensor, a carbon dioxide sensor, and a total volatile organic compound (tVOC) sensor, determining a gas quality index of the medical gas based on the obtained measurements, and outputting the determined gas quality index.

Described herein are examples of pharyngeal respirators. Pharyngeal respirators may include a connection end having a first outer width, a flange disposed on the connection end having a second outer width greater than the first outer width, and a socket disposed on the flange. The connection end may be insertably disposed within a receiver of a pharyngeal breathing tube. The flange may not fit within the receiving end of the pharyngeal breathing tube. The socket may receive a medical fitting. The connection end, the flange, and the socket may form a tubular structure having a first end comprising the connection end and a second end comprising the socket.

A connector for a component of a medical breathing circuit. The connector comprises an inner body and an outer body. The outer body is configured to be slidable along the inner body between each of an inoperative orientation and an operative orientation with respect to the inner body. The outer body and the inner body are configured to be in engagement or in an operative association with each other when the outer body is provided in the operative orientation. The outer body and the inner body are disengaged from each other or in an inoperative association with each other when the outer body is provided in the inoperative orientation. At least one or each of a surface of the inner body or a surface of the outer body comprises of a surface relief feature(s) providing for a resistance to the outer body being moved from the inoperative orientation to the operative orientation.
