摘要： A method of upgrading a medical device having a controller that controls operation of the medical device according to an operating routine executed by the controller. Upgrading the medical device includes communicating an external device, such as a conventional computer, with the controller. An external access key is provided to the external device and compared to an internal access key provided by the medical device. Upgrading of the medical device is enabled if the two access keys match. Upgrading includes modifying or rewriting the operating routine stored in the medical device. A medical device manufacturer, supplier, or seller controls the distribution of the external access keys, thereby providing the ability to track the medical devices being upgraded and the upgrade provided to that device.

摘要： A pressure generating system and method for generating a flow of fluid at a pressure above atmospheric pressure. The system includes a pressure generator and a valve that controls the pressure/flow of gas delivered to the patient. The system monitors energy provided to the valve, a characteristics associated with movement of the valve, a position of the valve, or any combination thereof. In addition, the controller controls an operating speed of the pressure generator such that the valve operates over a majority of the range of positions during use of the pressure support system.

摘要： A pressure generating system and method for generating a flow of fluid at a pressure above atmospheric pressure. The system includes a pressure generator and a pressure regulator downstream of the pressure generator. The system monitors a characteristic associated with the pressure regulator, the fluid flow downstream of the pressure regulator to the patient, the fluid flow upstream of the pressure regulator, the fluid flow exhausted from the pressure regulator, or any combination thereof. A controller coupled to the pressure generator controls an operating speed of the pressure generator based on the monitored characteristic(s) so that the output of the pressure generator is only kept as high as needed to provide the desired pressure to the patient.

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 ventilator supplies a plurality of volumes of fluid to a patient during a like plurality of inhalations by the patient. Each volume of fluid is supplied at an inspiratory positive airway pressure during a corresponding inhalation by the patient. A volume of fluid received by the patient is determined for each of the plurality of inhalations by the patient and an average volume of fluid received by the patient during each of the plurality of inhalations is determined. The average volume of fluid received by the patient during each inhalation is compared to a predetermined target volume and the inspiratory positive airway pressure each volume of fluid is supplied to the patient is adjusted as a function of the comparison.

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.
