Abstract: A ventilatory system for providing ventilatory support to a patient without the need for an external source of pressurized drive gas. The ventilatory system comprises a drive pump and a controller such that the drive pump collects ambient air and may pressurize it to a pressure determined by the controller. The controller may signal to the drive pump to pressurize the collected ambient air to a first pressure for delivering ventilatory support to a patient and a second pressure for providing PEEP support to a patient. The controller may signal to the drive pump to deliver a targeted flow and/or volume of collected ambient air to the bellows to provide volumetric ventilatory support during inhalation and a PEEP support during exhalation.

Abstract: A respiratory support system for providing respiratory support to a patient comprising an oscillating pump. The oscillating pump pressurizes ambient air to a pressure suitable for delivery to the patient for respiratory support. The system further comprises a sensor and a microprocessor to control the oscillating pump in response to patient breath attempts.

Abstract: The present invention is a system and method of independent control and regulation of blood gas, sedation, and pulmonary resistance using an intravascular membrane catheter. The system and method monitors a patient to determine whether the patient requires an adjustment of his level of sedation, pulmonary vascular resistance, or some other pre-determined physiological blood concentration that can be controlled by adjusting metabolic and inhaled anesthetic gas concentrations in the blood. A gas mixer or blender combines the O2 with the required gases, and the IGEC is reset to administer the gas mixture. To add an inhaled anesthetic such as desflurane, enflurane, halothane, isoflurane, sevoflurane, or some other anesthetic known in the art, the blended gases are directed through an anesthetic vaporizer, for example the TEC 5, TEC 6, TEC 7, or the Aladin™ vaporizer which are commercialized by GE Healthcare.

Abstract: A method and apparatus for supplying a breathing gas mixture to a patient in which a desired concentration of oxygen is maintained when nitric oxide (NO) is provided in the breathing gases. A clinician establishes at a ventilator, ventilation parameters for the patient, the inspired oxygen concentration, and the inspired NO dosage. From these quantities, a breathing gas mixture flow rate is determined. An instantaneous flow rate for an NO containing gas is determined, based on the concentration of nitric oxide in the supply gas and the instantaneous breathing gas mixture flow rate. An instantaneous flow rate for the supply of a balance gas, such as air, is determined using the breathing gas mixture flow rate, the instantaneous NO containing gas flow rate, and the inspired oxygen concentration established by the clinician.

Abstract: An arrangement and method for detecting spontaneous respiratory effort of a patient receiving ventilatory support by a breathing circuit. The nasal cannula control system includes a nasal cannula assembly having two distinct lumens. A different pressure sensor is positioned to detect the pressure difference between each of the two lumens, thereby determining the differential pressure from within the patient's nostrils and within a breathing mask. The nasal cannula control system includes a gas sampling system such that the amount of a monitored gas discharged or exhaled by the patient can be monitored using the same nasal cannula assembly used to generate the differential pressure signal.

Abstract: A multiple lumen nasal cannula that can be used to delivery two separate supplies of gases to a patient. The multiple lumen nasal cannula includes a first lumen for delivering a first gas and a second lumen for delivering a second gas. The first lumen includes support structure that reduces the tendency of the cannula to kink and lock the delivery of gas to a patient. The cannula assembly includes a mixing chamber positioned near the patient such that the two supplies of gas are not mixed until a location approximate to delivery to the patient. The nasal cannula assembly includes a connecting device that allows the two separate supplies of gas to be correctly delivered to the two different lumens of the nasal cannula.
