A method for controlling breathing gas flow of a ventilator for assisted or controlled ventilation of a patient as a function of a tracheobronchial airway pressure of the patient. A ventilator tube, such as a tracheal tube or tracheostomy tube, can be introduced into a trachea of the patient and subjected to the breathing gas, and has an inflatable cuff and at least one lumen that is continuous from a distal end of the tube to a proximal end of the tube. An apparatus detects an airway pressure, in which the tracheobronchial airway pressure is ascertained by continuous or intermittent detection and evaluation of an intra-cuff pressure prevailing in the cuff of the tube inserted into the trachea. The breathing gas flow of the ventilator is controlled as a function of the intra-cuff pressure detected.

Methods and apparatus provide continuous guidance of endoscopy during a live procedure. A data-set based on 3D image data is pre-computed including reference information representative of a predefined route through a body organ to a final destination. A plurality of live real endoscopic (RE) images are displayed as an operator maneuvers an endoscope within the body organ. A registration and tracking algorithm registers the data-set to one or more of the RE images and continuously maintains the registration as the endoscope is locally maneuvered. Additional information related to the final destination is then presented enabling the endoscope operator to decide on a final maneuver for the procedure. The reference information may include 3D organ surfaces, 3D routes through an organ system, or 3D regions of interest (ROIs), as well as a virtual endoscopic (VE) image generated from the precomputed data-set. The preferred method includes the step of superimposing one or both of the 3D routes and ROIs on one or both of the RE and VE images. The 3D organ surfaces and routes may correspond to the surfaces and paths of a tracheobronchial airway tree extracted, for example, from 3D MDCT images of the chest.

A closed suction system module is provided. In one embodiment, the closed suction system module comprises a coupling member configured to couple to a suction port of a multi-port manifold or endotracheal tube adapter (e.g., dual-port or tri-port adapter). In one embodiment, the closed suction system module comprises a suction catheter configured to clean the interior surfaces of body-inserted tubes or artificial airways (alone or in addition to suctioning natural airways or portions of the respiratory tract or other body lumens). The suction catheter may comprise a cleaning portion at a distal portion of the suction catheter (e.g., near the distal end or tip of the suction catheter). In some embodiments, the cleaning portion comprises at least one expandable cleaning member (e.g., balloon, sleeve, wiper).

By interposing an adapter between the endotracheal or tracheal tube inserted to a patient and the ventilation and suction systems that are connected to the endotracheal tube, a catheter could be inserted via an input port built into the adapter so as to enable a medical personnel to provide localized treatments in the lungs of a patient without having to disconnect either one of the systems connected to the endotracheal tube. The adapter is configured to have a securing mechanism that allows the medical personnel to secure the medication catheter in place. A one way valve fitted to the apertured arm that forms the input port of the adapter prevents any back flow of fluid from the input port. The catheter is manufactured with calibration markings, most likely equally spaced, and a radiopaque line along its length to enhance the maneuvering and the positioning thereof in the patient so that the distal tip of the catheter could be accurately positioned to the desired location of the patient's tracheal / bronchial tree. As a result, the localized treatment such as the injection of a medicament is accurately provided to the appropriate location where the need is the greatest.

A method of operating a ventilator assembly having inhalation and exhalation passages communicating with one another, and a respiration assembly that can perform repetitive respiratory cycles. The method includes (a) connecting the conduit with an open end of an endotracheal tube positioned within the trachea so that the open end leads into the airway below the vocal cords, (b) repetitively cycling the respiration assembly so that during the inhalation phase, gas in the inhalation passage flows through the endotracheal tube and into the airway, and during the exhalation phase, an exhalation valve is maintained relatively closed and the exhaled gases flow pass the vocal cords and out of the mouth thereby facilitating the patient's ability to speak, and (c) monitoring ring the pressure within at least one of the passages during both phases for determining the pressure within the patient for use in operating the ventilator assembly.

A coupling for connecting an air supply to a respiratory support device has a latching mechanism which prevents the coupling from inadvertently axially displacing from the respiratory support device after they have been mated in a pneumatically discrete path. Non-axial forces are used to disengage the coupling from the respiratory support device. The coupling may include a trailing end adapter which permits rotation of the coupling relative to the air supply rather than to the respiratory support device.

The present invention relates to closed catheter suction systems used to aspirate secretions from the trachea of a patient and to rinse the catheter after such aspiration. The apparatus comprises a flexible suction catheter encased within a sheath that is fixed to a vacuum source at its proximal end and extendable through an adapter assembly at its distal end, near the patient. The adapter assembly connects the closed catheter suction system to a patient connector, and a suction control valve at the proximal end operates to aspirate secretions and to rinse the catheter. The closed catheter suction system also includes a lavage port and a rinse port, the latter of which is positioned near the distal end and is isolated from the ventilation circuit through the innovative use of a rinse chamber and a one-way valve. Advantageously, the lavage port is positioned near the proximal end, away from the patient, so as to prevent the accidental leakage of lavage into the ventilation circuit. Further, both the lavage port and the rinse port include a self-closing fill-valve that prevents the accidental loss of ventilator volume and which also prevents the discharge of infectious pathogens to the surrounding environment throughout the aspiration and rinse procedures.

The present invention provides an improved means of treating tracheobronchitis, bronchiectasis and pneumonia in the nosocomial patient, preferably with aerosolized anti gram-positive and anti-gram negative antibiotics administered in combination or in seriatim in reliably sufficient amounts for therapeutic effect. In one aspect, the invention assures this result when aerosol is delivered into the ventilator circuit. In one embodiment the result is achieved mechanically. In another embodiment, the result is achieved by aerosol formulation. In another aspect, the invention assures the result when aerosol is delivered directly to the airways distal of the ventilator circuit. The treatment means eliminates the dosage variability that ventilator systems engender when aerosols are introduced via the ventilator circuit. The treatment means also concentrates the therapeutic agent specifically at affected sites in the lung such that therapeutic levels of administrated drug are achieved without significant systemic exposure of the patient to the drug. The invention further provides a dose control device to govern this specialized regimen.
