Abstract
Abstract A method system for measuring the rate of occurrence of physiological parameters, such as temperature, pulse rate and respiration rate. A method, implemented by a digital processor associated with an electronic measuring system, provides accurate measurements in a short period of time, which measurements are then displayed to the system operator. Automatic indicator signals or alarm signals are produced whenever data is determined to be invalid. The system is entirely self-contained and, upon completion of a measuring cycle, actuation of the appropriate function key, will visually display the valid data to the operator.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
240 words
A method for measuring a physiological parameter of a patient in a rapid manner by converting successive measurements of the physiological parameter into a final measurement value thereof, comprising the steps of: (a) detecting successive occurrences of the physiological parameter; (b) producing, in response to said successive occurrences of said physiological parameter, data points representing values of said physiological parameter; (c) comparing each of said data points with a predetermined range to determine those data points having a value falling within said predetermined range, and determining the number of said data points having a value falling within said predetermined range; (d) computing an average of all said data points having a value falling within said pre-determined range; (e) determining if said computed average falls outside of said predetermined tolerance limits, and if so, substituting said computed average as a new average; and (f) determining if said computed average falls within said predetermined tolerance limits, and if so, comparing the determined number of said data points having a value within said predetermined range with a pre-selected number, declaring the computed average to be an invalid calculation if the determined number of date points is less than said pre-selected number, and declaring the computed average to be a valid calculation if the determined number of date points is greater than said pre-selected number; whereby to rapidly obtain for display a valid final measurement value of the physiological parameter from said date points.
Claim 2
Independent Claim
240 words
A method for measuring a physiological parameter of a patient in a rapid manner by converting successive measurements of the physiological parameter into a final measurement value thereof, comprising the steps of: (a) detecting successive occurrences of the physiological parameter; (b) producing, in response to said successive occurrences of said physiological parameter, data points representing values of said physiological parameter; (c) comparing each of said data points with a predetermined range to determine those data points having a value falling within said predetermined range, and determining the number of said data points having a value falling within said predetermined range; (d) computing an average of all said data points having a value falling within said pre-determined range; (e) determining if said computed average falls outside of said predetermined tolerance limits, and if so, substituting said computed average as a new average; and (f) determining if said computed average falls within said predetermined tolerance limits, and if so, comparing the determined number of said data points having a value within said predetermined range with a pre-selected number, declaring the computed average to be an invalid calculation if the determined number of date points is less than said pre-selected number, and declaring the computed average to be a valid calculation if the determined number of date points is greater than said pre-selected number; whereby to rapidly obtain for display a valid final measurement value of the physiological parameter from said date points.
