According to the invention, methods and devices for increasing cardiopulmonary circulation induced by chest compression and decompression when performing cardiopulmonary resuscitation are provided. According to one method, a pressure responsive inflow valve is coupled to a patients airway. Chest compressions and chest decompressions are performed. During chest decompression the inflow valve prevents respiratory gases from entering the lungs until a certain negative intrathoracic pressure level is exceeded at which time the one inflow valve opens. In this way, the inflow valve assists in increasing the magnitude and duration of negative intrathoracic pressure during decompression to enhance the amount of blood flow into the heart and lungs. Further, the patient is supplied with a pressurized respiratory gas through the inflow valve when the inflow valve opens to ventilate the patient.

A method and device to enable a medical or surgical procedure using electro-cautery on a patient with an implantable device in a cautery-safe mode of operation. In one embodiment, the invention provides an electronic implantable device programmer having a computer processor, and a display screen configured to display information based on signals from the computer processor. The programmer also includes an input device, and a wireless transmitter controlled by the computer processor. The programmer display and input give the operator the option of programming an implanted electronic device in a cautery-safe mode. With this input, from the operator, instructions are provided in the programmer to transmit a signal from the wireless transmission device to the implanted electronic device to program the electronic device to be in a dedicated bipolar mode where electrical noise produced when operating an electro-cautery device during and medical/surgical procedure does not interfere with operation of the electronic device.

According to the invention, methods and devices for increasing cardiopulmonary circulation induced by chest compression and decompression when performing cardiopulmonary resuscitation are provided. Cardiopulmonary circulation is increased according to the invention by impeding airflow into a patient's lungs to enhance the extent and duration of negative intrathoracic pressure during decompression of the patient's chest. Enhanced extent and duration of negative of intrathoracic pressure thus promotes venous blood flow into the heart and lungs from the peripheral venous vasculature. In one embodiment, impeding the airflow into the patient's lungs is accomplished by placing a ventilation tube in the patient's airway. The ventilation tube contains either a flow restrictive orifice disposed within or connected in series with a lumen of the ventilation tube, or a pressure-responsive valve within a lumen of the tube to impede the inflow of air. In a preferred embodiment, the patient's mouth and nose are covered with a facial mask which can impede airflow into the patient's airway.

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.

A method for measuring the amount of adenylate cyclase without the use of radioactive reagents is provided. The method comprises combining a sample of physiological material containing an amount of cAMP with (a) a mixture of enzymes effective to eliminate any other endogenous adenine nucleotides which may be present in the sample; and (b) an amount of alkaline phosphatase effective to eliminate any glucose-6-phosphate present in the sample. The cAMP present in said sample is then converted to AMP and the amount of AMP measured, which may then be correlated to the amount of cAMP and AC present in the sample.

In one embodiment, the invention provides a device for decreasing intracranial or intraocular pressures. The device comprises a housing having an inlet opening and an outlet opening that is adapted to be interfaced with a person's airway. The device further includes a valve system that is operable to regulate respiratory gas flows through the housing and into the person's lungs during spontaneous or artificial inspiration. The valve system assists in lowering intrathoracic pressures during each inspiration to repetitively lower pressures in the venous blood vessels that transport blood out of the head to thereby reduce intracranial or intraocular pressures.

A facial mask includes a mask body that is adapted to be coupled to a patient's face. A valve system is coupled to the mask body to permit the inflow of respiratory gasses into the mask body and to permit the outflow of respiratory gasses from the mask body. A metronome is coupled to the mask body to produce a repeating chest compression signal to facilitate the performance of regular chest compressions when performing cardio pulmonary resuscitation. The metronome may also produce a ventilation signal to facilitate the proper ventilation of the patient.

A method is provided for non-invasively lowering a person's ICP and increasing cerebral perfusion pressure. The method may include the step of actively lowering the person's intrathoracic pressure. Also, the person's effective circulating blood volume is lowered while the person's intrathoracic pressure is lowered to thereby non-invasively reduce venous blood volume in the brain to treat elevated intracranial pressure.

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.
