Embodiment Construction

[0204] Figure 1 shows a prior art conventional ventilation system, commonly referred to as a continuous mechanical ventilation (CMV) system, in which a ventilator (V) is connected to a patient (P) using a dual-branch breathing circuit (2) The limb (IL) delivers gas to the patient, and gas is exhausted from the lungs through the exhalation valve (22) back to the expiratory limb (EL). A typical patient ventilation interface is an endotracheal tube (ETT) with a tracheal tube cuff (4) so ​​that the patient's lungs are closed from the outside air and only connected to the air source through the ventilator breathing circuit. Ventilators in CMV systems typically include one or more ambient relief valves to prevent lung overpressure in the event of an obstruction or high pressure event, and to enable access to outside air in the event of ventilator failure. The ventilator may include an inspiratory relief valve (8) so that the patient, if he has any breathing maneuver capability, can ...

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.

Description

[0001] This application claims the benefit of US Provisional Application No. 60 / 960,370, filed September 26, 2007, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to ventilation therapy for persons suffering from respiratory disorders and diseases such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, acute respiratory distress syndrome (ARDS), neuromuscular disorders and sleep apnea. [0003] In particular, the present invention relates to providing means for exhalation and inhalation through a ventilation tube in the event of an obstruction, otherwise the patient cannot properly inhale or exhale through their normal upper airway airway pathway. Background technique [0004] Two general types of ventilator or ventilation control systems are known in the prior art. The first type of ventilation control system delivers gas to the patient based on a frequency selected by the clinician and inde...
