| 20100024819 | APPARATUS, METHOD, SYSTEM AND COMPUTER PROGRAM FOR LEAKAGE COMPENSATION FOR A VENTILATOR - A ventilator apparatus, method, system, and computer program for determining leakage in a flow circuit providing pressurized gas to a patient having breathing disorder. The present invention determines the leakage by calculating a ratio between a measured flow of gas and a determined flow of gas related to a standard leakage. The determined standard leak flow may be calculated from a formula derived from Bernoulli's theorem. The invention may further be arranged to use a volume difference between inspiration and expiration phases in the compensation process. | 02-04-2010 |
| 20090188502 | ENERGY RELIEF CONTROL IN A MECHANICAL VENTILATOR - The present invention relates to a solution for controlling the pressure/flow of breathing gas to a mechanical ventilator ( | 07-30-2009 |
| 20090007912 | Ventilator for Supplying Breathable Gas to a Patient, and a Noise Reduction Method for Said Ventilator - A ventilator for supplying breathable gas to a patient includes an external housing; an internal housing suspended within; a gas flow generator within said internal housing; a gas inlet conduit extending between a first gas inlet opening in said external housing and a second gas inlet opening in said internal housing, and a gas outlet conduit extending from a first gas outlet opening in the internal housing via a second gas outlet opening in the external housing and to a patient interface means adapted for introducing the breathable gas into the airway of said patient. One or both of the gas inlet and outlet conduits exhibit a first substantially rigid conduit section and a second membrane conduit section with a membrane wall portion separating a volume of breathable gas within the gas inlet conduit and/or gas outlet conduit from a volume of ambient air within the external housing. | 01-08-2009 |
| 20080283061 | Energy Trigger - A method and apparatus for facilitating breathing using a mechanical breathing gas ventilator is presented. The patient effort is deduced from a measured flow signal and analyzed with respect to the energy in the breathing system comprising the mechanical ventilator and the patient. When a predetermined energy threshold has been reached the ventilator responds to the breathing pattern change. | 11-20-2008 |
| 20080276939 | Delta Flow Pressure Regulation - A method, system, apparatus, and computer program for detecting breathing pattern changes and controlling a mechanical ventilator in accordance to changes of breathing air flow thus reducing the work of breathing for the patient. | 11-13-2008 |
| 20080257349 | Multilevel Ventilator - A method and apparatus for detecting breathing disorders and controlling a breathing ventilator using an artificial neural network working on signals indicative of a patient's physiological status. Preferably the artificial neural network works on a signal indicative of the pressure or flow of supplied breathing gas divided into two or more intervals ( | 10-23-2008 |
