|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|
|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|
|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|
|20110098612||POSITIVE PRESSURE SYSTEMS AND METHODS FOR INCREASING BLOOD PRESSURE AND CIRCULATION - In one embodiment, the invention provides a medical method for treating a person and comprises repeatedly compressing the person's chest. While repeatedly compressing the person's chest, the method further includes repeatedly delivering a positive pressure breath to the person and extracting respiratory gases from the person's airway using a vacuum following the positive pressure breath to create an intrathoracic vacuum to lower pressures in the thorax and to enhance blood flow back to the heart.||04-28-2011|
|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|
|20100179442||SYSTEM FOR SENSING, DIAGNOSING AND TREATING PHYSIOLOGICAL CONDITIONS AND METHODS - One method for diagnosing a cardiovascular-related condition in a breathing person comprises interfacing a valve system to the person's airway. The valve system is configured to decrease or prevent respiratory gas flow to the person's lungs during at least a portion of an inhalation event. The person is permitted to inhale and exhale through the valve system. During inhalation, the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure. Further, at least one physiological parameter is measured both prior to and while the person inhales and exhales through the valve system. The measured parameters are evaluated to confirm the initial diagnosis of a cardiovascular condition.||07-15-2010|
|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|
|20090062701||LOWER EXTREMITY COMPRESSION DEVICES, SYSTEMS AND METHODS TO ENHANCE CIRCULATION - Systems and methods for enhancing circulation are described. In one particular embodiment, the invention provides a method for enhancing circulation. The method comprises attaching at least one compression device to at least a portion of a person's lower extremity. The person's chest is repetitively compressed so that the chest experiences a compression phase and a recoil phase or decompression. Also, the person's lower extremity is compressed using the compression device during at least some of the recoil phases.||03-05-2009|
|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|
|20080257344||VOLUME EXCHANGER VALVE SYSTEM AND METHOD TO INCREASE CIRCULATION DURING CPR - 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.||10-23-2008|
|20080255482||INTRATHORACIC PRESSURE LIMITER AND CPR DEVICE FOR REDUCING INTRACRANIAL PRESSURE AND METHODS OF USE - In certain aspects, the present invention relates to CPR devices that are designed to limit the rise in intrathoracic pressure when performing CPR compressions (e.g., chest, thorax, etc.) so as to minimize increases in intracranial pressure resulting from such compressions and elevated ITP. Exemplary CPR devices of the invention generally include one or more pressure sensors and a control system configured to adjust or alert for the need to adjust the amplitude and duration of CPR compressions so as to prevent a rise in ITP above a certain threshold amount, thereby controlling the rise in ICP during CPR. Methods of controlling a rise in ICP during CPR are also provided.||10-16-2008|
