摘要： The present invention pertains to a pressure support system in which a flow or volume of gas is measured without using a dedicated flow element used in a conventional flow meter. Instead, the present invention provides a tortuous gas flow path in which a pressure differential is created between two points in the tortuous path. This pressure differential created by the gas flow path provides the necessary pressure drop for measuring the gas flow and/or gas volume passing through the pressure support system.

摘要： A pressure support system that includes a pressure generating system employing a pressure generator that provides a primary flow of gas to a patient and a supplemental gas system providing a supplemental flow of gas to the patient. A selectively acutable valve associated with the supplemental gas system controls the supplemental flow of gas to the patient, and a control unit coupled to the pressure generating systems controls the valve based on conditions of the pressure generator in the pressure generating system, thereby controlling the flow of the supplemental gas to the patient based on the detected conditions of the pressure generator.

摘要： A humidifier for use with a pressure support system. The humidifier includes a body having an inlet, a fluid holding chamber, and an outlet. The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.

摘要： A pressure support system has a motor, a switching element that supplies power to motor windings, and a blower coupled to the motor. Rotation of the blower elevates a pressure of fluid in a patient circuit coupled to an outlet of the blower. A rotational speed controller maintains the motor at a set rotational speed corresponding to a selected pressure for the fluid in the patient circuit. The rotational speed of the motor is maintained by a switching signal provided by a rotational speed controller to the switching element to control the actuation of the switching element. A fluid parameter monitoring portion monitors a parameter associated with the flow of fluid in the patient circuit, such as the magnitude, direction, or volume, based on a characteristic, such as duty cycle, of the switching signal, or based on a characteristic of a control signal that is used to generate the switching signal.

摘要： An exhaust port assembly comprising a conduit carries a flow of gas. A vent assembly having a fixed exhaust area is provided on the conduit for venting a flow of exhaust gas from within the conduit to ambient atmosphere. The vent assembly is configured so as to minimize noise associated with the flow of exhaust gas passing to atmosphere, diffuse the flow of exhaust gas passing to ambient atmosphere over a relatively large area, and minimize the area occupied by the venting assembly on the conduit.

摘要： A pressure support system and method of treating disordered breathing that optimizes the pressure delivered to the patient to treat the disordered breathing while minimizing the delivered pressure for patient comfort. The controller in the pressure support system operates as a set of prioritized control layers, wherein each control layer competes for control of the pressure generating system to implement a unique pressure control process. The pressure support system also controls the pressure provided to the patient based on the variability of the monitored data and a trend analysis of this data, including an indication of the skewness of the patient's inspiratory waveform.

摘要： A system and method for delivering a flow of breathing gas to an airway of a patient. A characteristic that varies based on variations of the flow of the breathing gas is monitored and used to determine a Target Flow for the gas delivered to the patient. The Target Flow is set to a level sufficient to treat Cheyne-Stokes respiration or a sleep disordered breathing event. The Target Flow is altered if the patient experiences a sleep disordered breathing event. In a further embodiment, the system determines an apnea detection time (Tapnea) as Tinsp plus a constant, and delivers a machine triggered breath if an amount since the start of inspiration reaches Tapnea. Yet another embodiment monitors the characteristic during an inspiratory phase of a respiratory cycle, and controls the flow of gas during the inspiratory phase of the respiratory cycle based on a result of this comparison.

摘要： A method of changing between two operator stations in a cab of a locomotive for controlling the brakes of the locomotive and of a train of railway cars connected to the locomotive. The stations each have at least one brake handle and an associated selector switch, with each of the switches being electrically connected to a brake control computer. The method includes stopping the train if the train is in motion and placing the brake valve handles of the stations in a position to apply the brakes at full service. One of the operator stations is selected as an active station for braking the train while the other station is selected to be inactive. Signals are directed from the selector switches at the operator stations to the computer, the signals indicating which of the two stations is active and inactive. The computer is provided with the software that accepts a valid transition to the station selected by the operator as the active station.
