  • Publication number: 20130274571
    Abstract: Embodiments of the present disclosure provide a hypersaturation index for measuring a patient's absorption of oxygen in the blood stream after a patient has reached 100% oxygen saturation. This hypersaturation index provides an indication of the partial pressure of oxygen of a patient. In an embodiment of the present invention, a hypersaturation index is calculated based on the absorption ratio of two different wavelengths of energy at a measuring site. In an embodiment of the invention, a maximum hypersaturation index threshold is determined such that an alarm is triggered when the hypersaturation index reaches or exceeds the threshold. In another embodiment, an alarm is triggered when the hypersaturation index reaches or falls below its starting point when it was first calculated.

  • Patent number: 8274360
    Abstract: Physiological information can be stored in a dynamic round-robin database. Parameter descriptors may be used to identify parameter values in the records. The parameter values can be dynamically updated by changing the parameter descriptors. In addition, the size of files used in the database can be dynamically adjusted to account for patient condition. In certain implementations, the round-robin database can be adaptive, such that an amount of data stored in the database is adapted based on patient condition and/or signal condition. Additionally, medical data obtained from a clinical network of physiological monitors can be stored in a journal database. The medical data can include device events that occurred in response to clinician interactions with one or more medical devices and device-initiated events, such as alarms and the like. The journal database can be analyzed to derive statistics, which may be used to improve clinician and/or hospital performance.

  • Publication number: 20110213272
    Abstract: According to certain described aspects, multiple acoustic sensing elements are employed in a variety of beneficial ways to provide improved physiological monitoring, among other advantages. In various embodiments, sensing elements can be advantageously employed in a single sensor package, in multiple sensor packages, and at a variety of other strategic locations in the monitoring environment. According to other aspects, to compensate for skin elasticity and attachment variability, an acoustic sensor support is provided that includes one or more pressure equalization pathways. The pathways can provide an air-flow channel from the cavity defined by the sensing elements and frame to the ambient air pressure.

  • Publication number: 20110105854
    Abstract: Medical patient monitoring devices that have the capability of detecting the physical proximity of a clinician are disclosed. The medical patient monitoring devices may be configured to perform a first selected action when the presence of a clinician is detected in a first detection area, and to perform a second selected action when the presence of the clinician is detected in a second detection area. The medical patient monitoring devices may be configured to determine whether a clinician is present in a detection area based on the strength of a signal from a clinician token, and based on a signal strength adjustment value associated with the clinician token. When the presence of a clinician is detected in a detection area, the medical patient monitoring devices may be configured to perform a predetermined action that is determined from a remote database communicatively coupled thereto.

  • Publication number: 20110001605
    Abstract: Medical patient monitoring devices that have the capability of detecting the physical proximity of a clinician are disclosed. The medical patient monitoring devices may be configured to perform a selected action when the presence of a clinician is detected. Systems and methods for facilitating communication between medical devices that use different medical communication protocol formats are also disclosed. For example, a medical communication protocol translator can be configured to receive an input message formatted according to a first protocol format from a first medical device and to output an output message formatted according to a second protocol format supported by a second medical device using a set of translation rules. Medical monitoring reporting systems are also disclosed. The medical monitoring reporting systems may be used to analyze a stored collection of physiological parameter data to simulate the effect of changing various medical monitoring options.

  • Publication number: 20090119330
    Abstract: Physiological information obtained from a medical patient can be stored in a dynamic round-robin database. Parameter descriptors may be used to identify parameter values in the records. The parameter values can be dynamically updated by changing the parameter descriptors to provide for a flexible database. In addition, the size of files used in the database can be dynamically adjusted to account for patient condition. In certain implementations, the round-robin database can be adaptive, such that an amount of data stored in the database is adapted based on patient condition and/or signal condition. Additionally, medical data obtained from a clinical network of physiological monitors can be stored in a journal database.
