METHODS AND DEVICES FOR PROVIDING INSPIRATORY AND EXPIRATORY FLOW RELIEF DURING VENTILATION THERAPY

摘要

Respiratory support and/or controlledmechanical ventilation of a patient are provided. Aventilation apparatus may include a ventilator, atranstracheal prosthesis, and a respiratory relief device. Thetranstracheal prostheses and ventilation catheter may bearranged such that the patient can breathe freely throughthe upper airway and/or the tracheal prostheses. Respiratorysensors may measure a breathing rate, lung pressure,airway pressure, or a combination thereof. Pulsesof gas may be provided to the patient through theventilation catheter during inspiration. The pulses may havea first volume while the patient breathes normal and asecond volume when the sensors detect a cessation ofbreathing or reduction in breathing volume. The secondvolume may be provided at 1 - 5 times the normalbreathing rate, with a volume 25 - 500% times the firstvolume, or both.
