A capnography system includes a CO.sub.2 sensing system having a CO.sub.2 sensor configured to measure a CO.sub.2 concentration in exhaled breath of a subject, a processor configured to derive one or more breath related parameters based on the measured CO.sub.2 concentration, and a communication unit. The capnography system includes a tubing system configured to allow flow of respiratory gasses therethrough. The tubing system includes a connector configured to connect the tubing system to the CO.sub.2 sensing system and a communication component configured to provide an indication of a type of the tubing system to the communication unit. The communication unit is configured to transfer data to the processor based on the indication obtained from the communication component, and the processor is configured to change or suggest a change of an operation mode of the CO.sub.2 sensing system based on the data.

Unwinding a portion of a support helix that comprises a heating wire from a wall of a hose at an end of the hose; sleeving a length of heatshrink tubing at least partly onto the unwound portion of the support helix; heating the heatshrink tubing to shrink onto at least part of the unwound portion of the support helix; and at an end of the unwound portion, directly connecting the heating wire to an electrical contact of an electrical connector.

An intraoral inflatable isolator (III) for an oral cavity of a patient, the III including: a compressed-air port; and an inflatable membrane dimensioned to be insertable into the mouth and connected to the compressed-airport, the membrane being configured to inflate upon application of compressed air from the compressed-air port to isolate within the oral cavity.

A ventilator including a housing; a gas inlet port disposed in the housing and adapted to be coupled to a gas source to receive a flow of gas; a valve assembly coupled with the gas inlet port for controlling flow of gas from the gas inlet port to a gas outlet port disposed in the housing and adapted for being coupled to a patient interface to fluidly couple the gas outlet port to the airway of a patient; a controller module disposed in the housing, the controller module comprising a controller operatively coupled with the valve assembly to control operation of the valve assembly; an airway pressure sensor positioned between the valve assembly and the patient interface to measure air flow output into flowing into the airway of the patient; wherein the pressure sensor is operatively connected to the controller module to control the operation of the valve assembly in response to changes in air flow output measured by the airway pressure sensor during use.

A catheter body (210) defines a distal-most suction orifice (444) and an outer lateral wall (592), which defines a lateral opening (448) therethrough into a suction lumen (530). An inflatable-element outer wall (590) of an inflatable element (588) is mounted to the catheter body (210). An inner membrane (589) is positioned within the inflatable element (588) and is mounted to the catheter body (210) around the lateral opening (448) along a seal perimeter (583) around the lateral opening (448), so as to define a collapsible membrane portion (596) that (a) covers the lateral opening (448), and (b) together with the inflatable-element outer wall (590), defines an inflatable chamber (587) between the inflatable-element outer wall (590) and the collapsible membrane portion (596). The inner membrane (589) entirely surrounds the catheter body (210).

The present disclosure relates to a system and method for use of acoustic reflectometry information in ventilation devices. The system and method includes a speaker to emit sound waves into an intubated endotracheal tube (“ETT”) and a microphone to detect returning acoustic reflections. In addition, the system and method includes a reflectometry device in communication with a ventilation device for analyzing timings and amplitudes of the returning acoustic reflections to determine a size of a passageway around an ETT tip, location and size of ETT obstructions, and relative movement of the ETT tip within a trachea. The reflectometry device is also configured to determine a resistance parameter representative of resistance to actual flow of air through the ETT based upon a function of the diameter of the ETT, length of the ETT, and percent obstruction of the ETT, where the resistance parameter is used to calculate the tracheal pressure.

A sensor including electrodes, a control module and a physical layer module. The electrodes are configured to (i) attach to a patient, and (ii) receive a first electromyographic signal from the patient. The control module is connected to the electrodes. The control module is configured to (i) detect the first electromyographic signal, and (ii) generate a first voltage signal. The physical layer module is configured to: receive a payload request from a console interface module or a nerve integrity monitoring device; and based on the payload request, (i) upconvert the first voltage signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the sensor to the console interface module or the nerve integrity monitoring device.

Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.
