  • Publication number: 20200110541
    Abstract: A method for improving I/O response times in a data replication environment is disclosed. In one embodiment, such a method includes receiving, at a primary storage system, a request to read data on the primary storage system. The method starts a timer upon receiving the request. In the event the data cannot be retrieved from the primary storage system by the time the timer expires, the method requests the data from a secondary storage system. In the event the primary storage system returns the data before the secondary storage system, the method returns data retrieved from the primary storage system to a host system. In the event the secondary storage system returns the data before the primary storage system, the method returns the data retrieved from the secondary storage system to the host system. A corresponding system and computer program product are also disclosed.

  • Patent number: 9554740
    Abstract: An apparatus (10) for predicting patient respiratory stability includes a patient data memory (24) which stores patient data for a patient (12) and an analyzer (34) in communication with the memory computes a measure of patient respiratory stability. The analyzer applies one or more rules to the patient data that are based on a plurality of parameters which in combination, have been identified as being predictive of patient respiratory instability, such as mean airway pressure (MAWP), plateau pressure (PP), arterial oxygen saturation (SaO2 or SpO2), and heart rate (HR). Based on the application of the rules, the analyzer determines the measure of patient respiratory stability.

  • Patent number: 8878677
    Abstract: Medical vital signs (110) are captured, recorded, processed, and a signal quality assessment (160) is computed based on signal waveform components such as slope, amplitude, time to rise, time at peak, and degree to which signal peaks (420) and valleys (430). The signal assessment (160) may be used as a basis for rating the quality (130) of the underlying vital signal, to increase the quality of the signal by removing noisy segments and physiologically impossible peaks (42) and valleys (434), to detect a parameter value (120), to label a waveform (140), or to prompt an alarm (550) to indicate the signal has reached a critical level and issue a warning to the user of the vital data. The signal and the assessment are stored in an indexed, searchable data storage memory (590) from which the signals may be retrieved and displayed (300).
