An intubation assistance device includes an electronic controller configured to: generate a patient respiratory tract geometry model of at least a portion of a human respiratory tract by inputting one or more patient variables into a statistical shape model (SSM) of at least a portion of the human respiratory tract; select a recommended endotracheal tube (ETT) size by modeling at least one ETT model inserted into the patient respiratory tract geometry model to form a virtual fit model and estimating at least one fit parameter based on the virtual fit model; and display the recommended ETT size on a display device.

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.

Medical devices which are compatible with a camera for ventilating, intubating, and extubating a patient under continuous visualization. Methods for ventilating, intubating and extubating a patient with the medical devices.

A bougie is disclosed with a body, and a first depth indicator and a second depth indicator on the body. The body has a first end, a second end, and at least one surface extending between the first and second ends. The first depth indicator is spaced a first distance from the first end and indicates a first predetermined depth range such that the first end is positioned a first predetermined insertion range past the mouth of the patient when the body is positioned into the mouth of the patient. The second depth indicator is spaced a second distance from the second end and indicates a second predetermined depth range such that the second end is positioned a second predetermined insertion range past the mouth when the body is positioned into the mouth of the patient.

A laryngeal mask airway device (20, 320) is provided including an inflatable balloon (30, 330), which is (a) shaped so as to define at least an inflatable annular cuff (32, 332) and a proximal inflatable pharyngeal portion (34, 334), and (b) insertable through an anterior opening of a patients oral cavity. The inflatable balloon (30, 330) is configured such that when an inflatable chamber (56) thereof is filled with air at a pressure of 10 cm H2O and unconstrained, a volume of the air in a proximal one-third (60) of the inflatable chamber (56) equals at least 200% of a volume of the air in a distal one-third (62) of the inflatable chamber (56). Other embodiments are also described.

A tracheostoma device holder (10) for holding a tracheostoma device to a tracheostoma of a person is provided. The tracheostoma device holder (10) comprises a head portion (50) for engaging with a tracheostoma device and a fixation portion (20) for fixating the tracheostoma device holder (10) to the tracheostoma of the person. At least a portion of the fixation portion (20) is provided with a deformable material (60).

A method of ventilating a patient controls an actuator, in accordance with a prescribed value for a respiratory parameter, to compress an inflatable bag to cause air to flow out of an output valve of the bag. The respiratory parameter may include tidal volume, pressure, volume limit, peak pressure, I:E ratio, inspiratory time, and/or breathing rate of the air flowing through the output valve. The method also senses the pressure flowing through the output valve, and sends a pressure signal to the controller. Additionally, the method senses the flow rate through the output valve, and sends a flow rate signal to the controller. The method also adjusts the compression of the actuator as a function of the flow rate signal and/or the pressure signal to adjust the output tidal volume, pressure, volume limit, peak pressure, I:E ratio, inspiratory time, and/or breathing rate to be in accordance with the prescribed value.

An endotracheal tube cleaning device, including a rod, and a cleaning head coupled to a distal end of the rod, including a low friction-generating surface; and a high friction-generating surface, wherein the low friction-generating surface contacts an inner surface of the endotracheal tube when moved along the tube in a first direction and the high friction-generating surface contacts the inner surface of the endotracheal tube when moved in a second, opposite direction.

An endotracheal tube cleaning device, including a rod, and a cleaning head coupled to a distal end of the rod, including a low friction-generating surface; and a high friction-generating surface, wherein the low friction-generating surface contacts an inner surface of the endotracheal tube when moved along the tube in a first direction and the high friction-generating surface contacts the inner surface of the endotracheal tube when moved in a second, opposite direction.

A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distill ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.
