US 2009/0151724 A1 · METHODS AND DEVICES FOR PROVIDING INSPIRATORY AND EXPIRATORY FLOW RELIEF DURING VENTILATION THERAPY

Abstract

Respiratory support and/or controlled mechanical ventilation of a patient are provided. A ventilation apparatus may include a ventilator, a transtracheal prosthesis, and a respiratory relief device. The transtracheal prostheses and ventilation catheter may be arranged such that the patient can breathe freely through the upper airway and/or the tracheal prostheses. Respiratory sensors may measure a breathing rate, lung pressure, airway pressure, or a combination thereof. Pulses of gas may be provided to the patient through the ventilation catheter during inspiration. The pulses may have a first volume while the patient breathes normal and a second volume when the sensors detect a cessation of breathing or reduction in breathing volume. The second volume may be provided at 1-5 times the normal breathing rate, with a volume 25-500% times the first volume, or both.

Dependent claims

A ventilation apparatus comprising a ventilator, a gas delivery circuit, a transtracheal prosthesis or catheter, a respiratory relief device, and at least one respiratory sensor;

and wherein the one or more respiratory sensor is adapted to detect an obstruction of the airway, or adapted to predict an obstruction of the airway when the obstruction is developing;
and further wherein the respiratory relief device is adapted to open when the obstruction is detected or predicted.

A ventilation apparatus comprising

(a) a ventilator;
(b) a gas delivery circuit operably connected to the ventilator;
(c) a ventilation catheter operably connected to the gas delivery circuit;
(d) the ventilator adapted to provide a pulse of gas to the patient through the ventilation catheter during inspiration by the patient;
(e) a transtracheal prosthesis, wherein the ventilation catheter is placed coaxially in the transtracheal prostheses;
and wherein the transtracheal prostheses and ventilation catheter are arranged such that a patient using the ventilation apparatus can breathe freely through the patient's upper airway;
