Abstract: A method of providing a recruitment procedure to a patient includes monitoring at least derecruitment event. A score is calculated for the at least one derecruitment event. A derecruitment score is aggregated. The derecruitment score is compared to a recruitment threshold. A ventilator is operated with the processor to perform a recruitment procedure. A system for providing mechanical ventilation to a patient includes a mechanical ventilator configured for pneumatic connection to a patient in order to deliver medical gas to the patient. A peripheral system is configured to provide medical assistance to the patient and the peripheral system produces a signal indicative of the operation of the peripheral system. A processor is communicatively connected to the mechanical ventilator in the peripheral system. The processor receives the signal from the peripheral system and calculates a first score from the signal.

Abstract: A sound dampening apparatus to be disposed in pneumatic connection with a respiratory support system. The respiratory support system may comprise a source of medical gas, a plurality of pneumatic connections and a patient interface. The sound dampening apparatus comprises an inlet, an outlet, and an outer case which forms a sound dampening chamber. As the medical gas flows through the sound dampening apparatus, the noise energy associated with the flow of medical gas is reduced.

Abstract: An optimized system for providing medical support to a patient is disclosed. The system has a plurality of modular components that may be assembled to create a connection between a support machine and the patient wherein at least one of the modular components comprises an information tag for the storage of data and at least one of the modular components comprises an information sensor for the reading and transmission of the data. Once read and transmitted by the sensor, the data may be used to optimize the operation of the support machine.

Abstract: A method for identifying an occlusion in a breathing tube of a ventilator system is disclosed herein. The method includes obtaining data related to a respiratory signal, transferring the data to a processor, and implementing the processor to evaluate the data in a manner adapted to automatically identify the presence of an occlusion in the breathing tube. A corresponding ventilator system is also disclosed.

Abstract: A breath condensate sampler for use with a mechanical ventilator, the breath condensate sampler includes an airflow valve, a condensate formation tube, a condensate trap, and a condensate collection receptacle. The airflow valve directs air from the expiratory limb into the condensate formation tube wherein the condensate portion of exhaled gases are separated from the gaseous portion of the exhaled gases. A method of collecting a breath condensate sample is also herein disclosed.

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.

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.

Abstract: An input device for a clinician to control and modify the operation of a mechanical ventilator comprises a graphical display, a representation of a respiratory therapy trajectory to be delivered to a patient, at least one data point associated with the trajectory, and a data input means for the clinician to select a data point and to modify the value of the trajectory at that data point. The present invention provides for the creation and modification of a respiratory therapy trajectory, wherein the ventilator provides a medical gas waveform to a patient according to the respiratory therapy trajectory.

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.
