51results about How to "Increase gas exchange" patented technology

Methods of increasing gas exchange performed by the lung by damaging lung cells, damaging tissue, causing trauma, and / or destroying airway smooth muscle tone with an apparatus inserted into an airway of the lung. The damaging of lung cells, damaging tissue, causing trauma, and destroying airway smooth muscle tone with the apparatus may be any one of or combinations of the following: heating the airway; cooling the airway; delivering a liquid to the airway; delivering a gas to the airway; puncturing the airway; tearing the airway; cutting the airway; applying ultrasound to the airway; and applying ionizing radiation to the airway.

It has been discovered that high amplitude, low frequency, broadband spectrum pressure oscillations of sufficient time duration can help stabilize lung volumes and improve gas exchange in a patient receiving ventilation assistance by helping to recruit and stabilize alveoli. A novel device is presented which can produce pressure oscillations having high amplitudes, a low broad-band frequency spectrum and long time duration. Additionally, the device can maintain a patient's mean airway pressure at one or more controlled levels. The device can control the oscillatory amplitude, frequency range and composition, time duration, and mean airway pressure levels by adjusting certain device parameters, such as the angle and depth of the device in a fluid. A device and mechanical system for remotely adjusting and measuring the angle of the device in a fluid are also disclosed. Furthermore, a device and system are disclosed that can deliver pressure oscillations having high amplitudes, a low broad-band frequency spectrum, long time duration, and multiple mean airway inspiratory and expiratory pressure levels. The device and system also provide means for controlling respiration timing in a patient, including: breaths per minute, inspiratory time, and the ratio of inspiratory to expiratory time.

A paracorporeal respiratory assist lung is configured with an annular cylindrical hollow fiber membrane (fiber bundle) that is rotated at rapidly varying speeds. Fluid (for example, blood) is introduced to the center of the device and is passed radially through the fiber bundle. The bundle is rotated at rapidly changing velocities with a rotational actuator (for example, a motor or magnetic coupling). The rotation of the fiber bundle provides centrifugal kinetic energy to the fluid giving the device pumping capabilities and may create Taylor vortexes to increase mass transfer. Rotation of the fiber bundle increases the relative velocity between the fluid and the hollow fibers and increases the mass transfer. The porosity of the fiber bundle may be varied to enhance gas exchange with the blood. Alternatively, a rotating core may be used with a stationary fiber bundle.

Device for catalytic treatment of a gas flow including at least one body (1) that includes a catalytic material. The device has a number of first openings (5) for either entry of gas into or exit of gas from the catalyzer body (1), and a second opening (6) for either exit of the gas entering through the first openings or entry of gas into the catalyzer body (1) for subsequent exit through the first openings.

A gas sensor has shock resistance and temperature resistance attributes. The gas sensor includes at least one catalytic measuring element (3), which is arranged in a sensor housing (1) forming a combustion chamber (2). The sensor housing (1) has at least one gas-permeable housing opening (4) for the gas exchange between the environment and the combustion chamber (2). The catalytic measuring element (3) is arranged between at least two disk-shaped support elements (5) made of a heat-insulating and temperature-resistant material.

A collateral ventilation bypass trap system directly linked with a patient's lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating one aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter / one-way valve, an air carrying conduit and a retention device for securing system elements in position. The system also includes a flow restriction device for controlling the flow of air through the air carrying conduit.

The invention relates to the novel use of PDE5 inhibitors for the treatment of patients in which a mismatch is present.

The invention relates to the combined administration of a PDE4 inhibitor and a PDE5 inhibitor for the treatment of a disease in which phosphodiesterase 4 (PDE4) and / or phosphodiesterase 5 (PDE5) is detrimental.

A method for operating an auto-ignition internal combustion engine that is operable in a single substance mode in which the internal combustion engine is supplied with self-igniting liquid fuel, and a dual substance mode in which the internal combustion engine is supplied with the liquid fuel as an ignition agent and gaseous or liquid alternative fuel, includes operating the internal combustion engine in the dual-substance mode at an increased exhaust gas recirculation rate relative to the single-substance mode, and throttling an air supply in an intake system of the internal combustion engine such that a lambda value in an exhaust gas of the internal combustion engine is in a range greater than 1 up to 1.3.
