The invention describes a process for determining a biological state through the discovery and analysis of hidden or non-obvious, discriminatory biological data patterns. The biological data can be from health data, clinical data, or from a biological sample, (e.g., a biological sample from a human, e.g., serum, blood, saliva, plasma, nipple aspirants, synovial fluids, cerebrospinal fluids, sweat, urine, fecal matter, tears, bronchial lavage, swabbings, needle aspirantas, semen, vaginal fluids, pre-ejaculate.), etc. which is analyzed to determine the biological state of the donor. The biological state can be a pathologic diagnosis, toxicity state, efficacy of a drug, prognosis of a disease, etc. Specifically, the invention concerns processes that discover hidden discriminatory biological data patterns (e.g., patterns of protein expression in a serum sample that classify the biological state of an organ) that describe biological states.

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 devices for treating bronchial constriction related to asthma and anaphylaxis wherein the treatment includes providing an electrical impulse to a selected region of the vagus nerve and / or the lungs of a patient suffering from bronchial constriction.

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.

BACKGROUND: Tracheotomy is used to assist patients who require mechanical ventilation. Tracheostomy is a common surgical procedure for intensive care patients. The goals of tracheotomy are to bypass the upper airway, facilitate removal of tracheobronchial secretions, prevent aspiration of gastric contents, and to control the airway for prolonged mechanical ventilation. METHOD: The hypothesis to improve the design of the tracheostomy tube, making it easier to use and eliminating most of the disadvantages found in prior tracheostomy tubes. RESULTS: This device is an improved tracheostomy tube designed with the balloon cuff (18), guide balloon (26), balloon connector (32) and guide balloon valve (24) located on the inner cannula (12). The major improvement in this tracheostomy tube is that the removal of the outer cannula will not be necessary when the balloon cuff is damaged, since replacing the inner cuffed cannula corrects the problem.
