    摘要： Spontaneous respiration is detected by sensors. An additional amount of oxygen is administered to the lungs via a jet gas current at the end of an inhalation procedure. Breathing volume, absorption of oxygen during inhalation, and clearance of carbon dioxide during exhalation are improved. If required, the exhalation procedure of the patient can be arrested or slowed by a countercurrent to avoid a collapse of the respiration paths. An apparatus including an oxygen pump can be connected to an oxygen source and includes a tracheal prosthesis that can be connected via a catheter. The respiration detections sensors are connected to a control unit for activating the oxygen pump. The tracheal prosthesis includes a tubular support body with a connection for the catheter, and the sensors are associated with the support body. The tracheal prosthesis and jet catheter are dimensioned so the patient can freely breathe and speak without restriction.

    摘要： Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redistributing inspired air to other healthier lung areas, for treating respiratory disorders such as COPD, ARDS, SARS, CF, and TB. Trans-Tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. The catheter can be left in place for extended periods without clinician attendance or vigilance. Ventilation includes delivery of respiratory gases, therapeutic gases or agents and evacuation of stagnant gases, mixed gases or waste fluids. Typically the catheter's distal tip is anchored without occluding the bronchus but optionally may intermittently or continuously occlude the bronchus. TTSV is optionally performed by insufflation only of the area, or by application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.
