摘要： Methods and apparatus for detecting apnoea that use ultrasonic sound waves are disclosed. The method consists of applying ultrasonic sound waves of varying frequency to a patient's airway and detecting their reflected sound waves. The sound waves are then analysed to determine whether there is a narrowing of the airway. In particular a transmitting ultrasonic transducer and receiving ultrasonic transducer are located on the interior surface of a mask and positioned so as to be directed towards the nares of the patient. A signal is emitted through the transmitting transducer and received at the receiving transducer. The received signal indicates a distance to a reflection or a distance to the narrowing of the upper respiratory tract. In this manner obstructions or narrowing of a patient's airway tract may be identified as reflections which appear at anatomically appropriate distances.

摘要： A method for providing respiratory support to a patient includes intubating the patient with an invasive patient interface having a sealable member operable to form a sealing engagement with the patient's airway. While the patient is intubated, the sealable member is operated to form a non-sealing arrangement of the invasive patient interface within the patient's airway and a flow of respiratory gas is provided to the patient via the invasive patient interface. This respiratory support is provided during absence of spontaneous breathing.

摘要： A connector is provided for coupling with an invasive patient interface for providing respiratory support to a patient. The connector comprises a connector body having: (i) an inlet port couplable with a flow source providing a flow of respiratory gas; (ii) a gases exit port; and (iii) a device port couplable with the invasive patient interface. The connector also has a lumen having a first end and a second end. The connector body defines a gas flow path between the inlet port and both the device port and the lumen first end and the lumen second end is disposed outside the device port. The lumen provides improved CO2 clearance. Some embodiments provide for gas sampling and/or variable expiratory resistance.

摘要： A system for providing respiratory support to a subject includes a flow source for providing a gas at a selected flow rate, an invasive respiratory device couplable with an airway of the subject, and a connector for coupling with the invasive respiratory device. The connector includes a main body having a gases port for receiving a flow of gas from the flow source, an outlet port for outflow of gases from the main body, and a device port couplable with the invasive respiratory device. The gases port includes an inlet and an outlet. The connector is configured to receive the flow of gas from the flow source via the inlet of the gases port, and to deliver a jet flow of gas through the outlet of the gases port. The system may be configurable e.g. to generate a pressure of at least about 2 cmH2O about the device port when in use.
