摘要： The disclosure describes techniques for protecting patient data stored in a medical device, such as an external defibrillator. The patient data may be transferred, or downloaded, from the medical device to another device, such as to a computing device for storage or analysis. In response to the download, the medical device may protect the patient data so that at least subset of users can no longer access the patient data. Patient data may be protected by modifying the data form, encrypting the data, moving the data to another memory module, password protecting the patient data, or modifying an access control list associated with the patient data. While the patient data may also be deleted as a technique for protecting the data, not deleting the data may allow the data to be recovered at a later time by an authorized user, i.e., a user not part of the subset.

摘要： A method and system for controlling the intervals during which light signals are sampled in a fiber-optic sensing system compensates for signal artifacts that are caused by movement of the fiber-optic waveguide during the sampling. The method and system sample the light signals at intervals that are shorter than the intervals during which displacement of the optical waveguide occurs in normal use. The short-sampling intervals result in the individual sampling of different wavelengths of light being exposed to the same changes in transmission characteristics of the optical waveguide which causes signal artifacts. Accordingly, when subsequent processing of the collected signals occurs, the effects of the signal artifacts are compensated for.

摘要： A calibration system and method for calibrating a medical sensor (16) that monitors chemical blood gases. A calibrator (12) is used in connection with a tray (14) in which the medical sensor is stored in a sterile environment, both before and during the calibration process. The medical sensor is immersed in a liquid (30) in a tonometry chamber (28) defined in the tray and covered by a membrane (120/122) that is permeable to gas, but impermeable to bacteria. During the calibration process, the tray is inserted into the calibrator, bringing a heated platen (26) into contact with the tonometry chamber, so that the liquid can be heated to a calibration temperature substantially equal to the temperature at which the medical sensor will subsequently be used. A first calibration gas is then bubbled through the liquid until a saturated condition is achieved. Once the temperature of the liquid is increased to the desired calibration temperature, as determined by a temperature sensor on the medical sensor, data for a first calibration point is taken. A second calibration gas is then bubbled through the liquid until saturation is achieved, yielding data for a second calibration point, for each of the chemical blood gas parameters. The calibration data is processed to determine calibration coefficients that will be applied to the medical sensor.

摘要： A system synchronizes the time of a clock of an electronic physiological instrument with time of a remote time base. The electronic physiological instrument records medical event data and electronically associates event time with the event data While recording, or after recording, the medical event data, the electronic physiological instrument is placed in data communication with the remote time base over a data connection. The remote time base initially determines a reference time from a master clock. The remote time base also transmits a request to the electronic physiological instrument for a current time from a clock in the electronic physiological instrument. If a response is not received from the electronic physiological instrument within a first time period, the clock is not synchronized with the remote time base. If a response is received within the first time period, a time difference is determined between the reference time and the time transmitted from the electronic physiological instrument by subtracting the two times. The time difference is then electronically associated with the medical event data. Associating the time difference with the medical event data allows the time stamps in the event data to be corrected to provide meaningful event reconstruction and analysis independent of any time differences between the two clocks and any time delays incurred in receiving the time from the physiological instrument over the data connection.
