  • Patent number: 7520279
    Abstract: A methodology and apparatus for determining a target ventilation setting for delivering ventilatory support based upon a function of measured PCO2. Patient ventilation is measured over time during a learning period in which ventilatory support is provided. A target ventilation is calculated as a function of the measured ventilation. Adjustments to the target ventilation are then made using a measure of partial pressure of CO2 for the patient. Preferably, the measure is compared to a threshold PCO2 and the target ventilation may be increased or decreased based upon the comparison. The target ventilation may then be increased or decreased based upon a fixed percentage of the absolute value of the difference between the measured PCO2 and the threshold PCO2.

  • Patent number: 7520280
    Abstract: A rebreather apparatus having a gas scrubber canister with a generally oval or elliptical cross section. The canister being configured so that exhaled gases pass through the adsorbent in a radial manner through a generally hollow tube having the same cross sectional shape as the canister. The shape of the canister allows for increasing the volume of the canister relative to round cylinder shaped canisters without making it too cumbersome such that it effects the efficiency of a diver. The canisters have at least one removable end cap and the end caps are configured for housing gas addition and control systems. The rebreather apparatus can be rapidly reconfigured to provide a variety of fully closed or semi closed circuit configurations and it can be reconfigured to be worn in a variety of ways based on tasks to be performed and diver preference.

  • Patent number: 7500483
    Abstract: This invention is a neonatal airway adapter (10) with a sliding internal passage (54), which virtually eliminates void volumes (112) within the bore (76) of the airways, such that mixing of the exhales pages with void gases is reduced, and the waveform of the breath is maintained without undue distortion. Furthermore, the virtual elimination of void volumes reduces the level of re-breathing. The neonatal airway adapter connects to endotracheal tube adapters is such a way as to nullify the effect of the differing internal diameters (20) and internal lengths which are used in ET adapters currently available. The cross section of the internal bore of the airway through which the breath flows from the ET adapter to the connector of the ventilator is maintained almost constant, especially in the region of the gas sampling point (66), to ensure that reasonable conditions of laminar flow, and accurate sampling are maintained.

  • Patent number: 7497217
    Abstract: Method for making a filter cartridge that is suitable for attachment to a respiratory mask. The method comprises the steps of (a) providing a mass of filter material; (b) providing a filter cartridge housing that has an inlet and outlet and a sidewall that includes sheet material; and (c) thermoforming the sheet material of the housing sidewall around at least part of the mass of filter material to place the housing sidewall in direct contact with the mass of filter material to encapsulate the filter material so that fluid is prevented from passing through the filter cartridge from the inlet to the outlet without being filtered by the mass of filter material.

  • Patent number: 7487774
    Abstract: The present invention is a method and system for adaptively detecting a patient trigger threshold. The system and method uses fuzzy-logic control algorithm to detect an appropriate trigger threshold by monitoring the number of patient triggers within a predetermined time frame. The system and method also detects an appropriated trigger threshold by monitoring the complete absence of false triggers over a predetermined time frame, increases in average flow, increases in pressure differential, and pressure drop, in order to lower the trigger threshold. The method and system of the present invention is selectable to the user, and adaptively changes the inspiratory trigger threshold.

  • Patent number: 7478634
    Abstract: The respiratory booster machine is configured to generate and transmit particularly designed and timely delivered vibrations to the lungs of a subject to improve ventilation, augment diffusion of gases across alveolar membrane, facilitate pulmonary blood perfusion, prevent focal alveolar collapse, and enhance effective expectoration. The machine has an acoustic signal generator having modulated wave-generating circuitry and an acoustic signal transmitter having an electro-acoustic transducer. Vibrations from the acoustic signal are induced into the subject's air stream, in one embodiment by a specially designed tube system, and then transmitted to a subject's airways via any type of endotracheal tube, respiratory mask, nasal prong, or directly through the chest wall. Acoustic signal receivers connected to a computer receive and analyze the effect of the vibrations on the subject.
