20090020128 | METHOD AND SYSTEM TO DECREASE INTRACRANIAL PRESSURE, ENHANCE CIRCULATION, AND ENCOURAGE SPONTANEOUS RESPIRATION - Systems and methods are provided for decreasing intracranial pressure and enhancing circulation in a breathing person, as well as for increasing the respiratory rate and encouraging spontaneous respiration. According to such methods, a valve system is interfaced to a person's airway. The valve system has a threshold valve and an airway member that interfaces with the person's airway. The threshold valve is configured to prevent respiratory gas flow to the person's lungs during a portion of an inhalation event until the inspiration equals or exceeds an opening pressure of the threshold valve. Also, a small level of external vacuum is constantly supplied at a juncture between the threshold valve and the airway member. | 01-22-2009 |
20090277447 | SYSTEM, METHOD, AND DEVICE TO INCREASE CIRCULATION DURING CPR WITHOUT REQUIRING POSITIVE PRESSURE VENTILATION - In one embodiment, the invention provides a method for performing cardiopulmonary resuscitation which comprises: 1) interfacing an airway system with a patient's airway, wherein the airway system includes at least a first lumen and a second lumen; 2) repeatedly performing CPR chest compressions on the patient; and simultaneously with the CPR chest compressions; 3) applying a continuous vacuum to the first lumen for a period of time ranging from 10 seconds to the end of the CPR chest compressions; and 4) injecting an effective volume of oxygen gas into the person's lungs at high velocity through the second lumen. | 11-12-2009 |
20100319691 | VACUUM AND POSITIVE PRESSURE VENTILATION SYSTEMS AND METHODS FOR INTRATHORACIC PRESSURE REGULATION - Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment. | 12-23-2010 |
20110201979 | GUIDED ACTIVE COMPRESSION DECOMPRESSION CARDIOPULMONARY RESUSCITATION SYSTEMS AND METHODS - Systems and methods for applying guided active compression decompression cardiopulmonary resuscitation are provided. Exemplary systems include a load cell, a handle, an adhesive pad. The handle and the adhesive pad are configured for magnetic coupling. | 08-18-2011 |
20120029321 | AIRWAY ADJUNCT RESUSCITATION SYSTEMS AND METHODS - Embodiments of the present invention encompass systems and methods for administering intrathoracic pressure and cooling treatments to patients suffering from or at risk of developing heart failure, cardiac arrest, sepsis, shock, acute respiratory distress syndrome, polytrauma, head disease, elevated hepatic or portal vein pressures, bleeding during abdominal, head and neck surgery, or insufficient circulation during open heart surgery. | 02-02-2012 |
20120216804 | CPR VOLUME EXCHANGER VALVE SYSTEM WITH SAFETY FEATURE AND METHODS - A method for regulating gas flows into and out of a patient includes repetitively forcing respiratory gases out of the lungs. Respiratory gases are prevented from entering back into the lungs during a time between when respiratory gases are forced out of the lungs. Periodically, an oxygen-containing gas is supplied to the lungs. | 08-30-2012 |
20120330200 | ENHANCED GUIDED ACTIVE COMPRESSION DECOMPRESSION CARDIOPULMONARY RESUSCITATION SYSTEMS AND METHODS - Systems and methods for applying enhanced guided active compression decompression cardiopulmonary resuscitation are provided. Exemplary systems include a load cell, a handle, an adhesive pad. The handle and the adhesive pad are configured for magnetic coupling. | 12-27-2012 |

20140324763 | SYSTEMS AND METHODS TO PREDICT THE CHANCES OF NEUROLOGICALLY INTACT SURVIVAL WHILE PERFORMING CPR - According to one aspect, a method for predicting the likelihood of survival of a particular individual with favorable neurological function during a cardiopulmonary resuscitation (CPR) procedure includes obtaining an electroencephalogram (EEG) signal of the particular individual during the CPR procedure. The method also includes obtaining a non-invasive measure of circulation of the particular individual during the CPR procedure and generating a prediction for the likelihood of survival of the particular individual with favorable neurological function based on the EEG signal and the non-invasive measure of circulation. | 10-30-2014 |
20150045704 | SYSTEMS AND METHODS TO INCREASE SURVIVAL WITH FAVORABLE NEUROLOGICAL FUNCTION AFTER CARDIAC ARREST - A system includes a guidance device that provides feedback to a user to compress a patient's chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters to about 6 centimeters. The system includes a pressure regulation system having a pressure-responsive valve that is configured to be coupled to a patient's airway. The pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function. The pressure-responsive valve is configured to remain closed until the negative pressure within the patient's airway reaches about −7 cm H | 02-12-2015 |
