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.

Enhanced guided active compression decompression cardiopulmonary resuscitation systems and methods

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.

Vacuum and positive pressure ventilation systems and methods for intrathoracic pressure regulation

Embodiments of the present invention provide systems and methods for delivering respiratory treatment to a patient. For example, a treatment system may include a mechanism for delivering a positive pressure breath to a patient, and one or more limb flow control assemblies which modulate gas flow to and from the patient. Exemplary treatment techniques are embodied in anesthesia machines, mechanical ventilators, and manual ventilators.

Systems and methods for therapeutic intrathoracic pressure regulation

Systems and methods are provided for decreasing intracranial pressure and enhancing circulation, as well as for increasing the respiratory rate and encouraging spontaneous respiration. According to such methods, a valve system is coupled with a person's airway. The valve system has an exhalation valve and an patient port that interfaces with the person's airway. The exhalation valve includes a diaphragm having a textured surface. The diaphragm is positioned across an exhalation valve seat and contacts a distal end of the exhalation valve seat, and is configured to prevent or impede respiratory gas flow to the person's lungs until an expiratory pressure equals or exceeds an opening pressure of the exhalation valve, at which time the diaphragm moves away from the distal end to create an open exhaust channel.

Guided active compression decompression cardiopulmonary resuscitation systems and methods

A gas blender with auxiliary mixed gas outlet for mixing a primary gas, generally air, and a secondary gas, generally oxygen, to obtain a mixed gas having several controlled characteristics. The gas blender may be incorporated into a Continuous Positive Airway Pressure (CPAP) device. The gas blender controls the mixing to produce the mixed gas having a predetermined mixture setpoint, generally an oxygen percentage, and a predetermined control setpoint, generally a pressure setpoint or flow rate setpoint. The gas blender provides an auxiliary mixed gas source for use by an auxiliary piece of equipment such as a nebulizer or resuscitation bag. The gas blender includes a primary gas inlet passageway, a secondary gas inlet passageway, a gas mixing apparatus, a mixed gas distribution passageway with an auxiliary mixed gas outlet, a gas sensor, a delivery sensor, a mixed gas delivery control valve, a mixed gas controlled passageway, and a controller.

Gas blender with auxiliary mixed gas outlet

A method for increasing circulation and providing oxygen to a patient in cardiac arrest includes the step of coupling an interface to the patient's airway, the interface providing access to the patient's respiratory system. A valve system is operably attached to the interface. Oxygen is delivered through the interface a rate of between about 1.0 to about 10.0 L/min to provide a continuous supply of oxygen to the patient. While supplying the oxygen, a body structure of the patient is manipulated to increase the magnitude and duration of the patient's negative intrathoracic pressure. During the manipulation, the valve system prevents additional respiratory gases from entering the lungs until a negative intrathoracic pressure level in the range from about &#x2212;1 cm H2O to about &#x2212;15 cm H2O, the valve system assisting in increasing the magnitude and duration of negative intrathoracic pressure thereby enhancing the amount of blood flow in the heart and lungs and lowering intracranial pressure, therein further increasing blood flow to the brain.
