Abstract: Ultrasound is used to provide input data for a blood pressure estimation scheme. The use of transcutaneous ultrasound provides arterial lumen area and pulse wave velocity information. In addition, ultrasound measurements are taken in such a way that all the data describes a single, uniform arterial segment. Therefore a computed area relates only to the arterial blood volume present. Also, the measured pulse wave velocity is directly related to the mechanical properties of the segment of elastic tube (artery) for which the blood volume is being measured. In a patient monitoring application, the operator of the ultrasound device is eliminated through the use of software that automatically locates the artery in the ultrasound data, e.g., using known edge detection techniques. Autonomous operation of the ultrasound system allows it to report blood pressure and blood flow traces to the clinical users without those users having to interpret an ultrasound image or operate an ultrasound imaging device.

Abstract: A technique is provided for determining service intervals for devices, such as medical equipment. Data related to a device is collected and compared to data from a population of like devices. A service interval may be calculated based on the comparison. The data regarding the population of like devices may be raw quantitative or qualitative data or may be processed data, such as may be used to graph the reliability of the device as a function of some variable such as usage or age, i.e. a reliability curve. The data may representative of the device as a whole or one or more components of the device. Multiple service intervals may be generated for a single device by calculating a service interval for each data source, such as a component or subset of components, of the device. An optimal service interval may then be selected. In addition, the technique may be applied for selection of a service interval for more than one device.
