Abstract

An intelligent printer-plotter for use with a source of time-correlated digital systolic and diastolic blood pressure data and heart rate data receives, stores, analyzes, and edits the data, producing tables of data and graphs having a particular format. The charter smooths the data by a moving average technique and includes modes which permit the operator to edit the data manually or to command the charter to perform the editing automatically. In the automatic editing mode, the data are tested against pre-established criteria. Data not meeting the criteria is flagged so that it can be passed over in subsequent calculation and printing operations; however, the flagged data is not destroyed, but is retained in a memory to permit subsequent re-examination and to permit verification of the editing process.

Claims

1. A charter for use with a source of time correlated digital systolic and diastolic blood pressure data and heart rate data, for receiving, storing, analyzing, and editing the data, and for producing tables and charts having a particular format for displaying under control of an operator in edited and unedited form both the data as received from the source and the analyzed data, said charter comprising in combination:

first storage means connected to the source of data for storing words of data when they are received from the source of data, and including flag storage locations associated with each of the words of data for storing as required a flag along with each word of data;

automatic editing means connected to said first storage means and operable in response to an edit command to edit by testing stored words of data to determine whether the stored words of data meet certain pre-established qualifications and to write a flag in the flag storage location associated with each of the stored words of data if the stored words of data do not meet the pre-established qualifications, so that edited data words meeting the pre-established qualifications can subsequently be recognized by the absence of a flag in their associated flag storage locations, both the edited and unedited data being retained in said first storage means after editing for selected use including verification and evaluation of the operation of said automatic editing means.

2. The charter of claim 1 further comprising:

manual editing means connected to said first storage means and operable under control of an operator for writing a flag in the flag storage location associated with a selected stored word of data.

3. The charter of claim 2 further comprising:

printer means connected to said first data storage means and displaying under control of the operator the unedited stored data words in a particular format to enable the operator to select a data word to be deleted, and displaying under control of the operator the edited stored data words to permit the operator to verify that the editing has been done correctly, both the edited and unedited data being retained thereafter in said first storage means for selected use including subsequent re-examination of the unedited data by the operator.

4. The charter of claim 1 wherein said pre-established qualifications include a range of acceptable magnitudes, a flag being written by said automatic editing means in the flag storage location associated with a stored word of data if the magnitude of the stored word of data is not within the range of acceptable magnitudes.

5. The charter of claim 1 wherein said pre-established qualifications include pre-established relations between substantially concurrent systolic and diastolic blood pressure data, a flag being written by said automatic editing means in the flag storage location associated with the stored systolic and diastolic blood pressure data if any of the pre-established relations does not obtain.

6. The charter of claim 1 further comprising:

arithmetical means connected to said first storage means for averaging stored words of systolic blood pressure data, for averaging stored words of diastolic blood pressure data, and for averaging stored words of heart rate data, and operable to employ in the averaging the unedited or the edited data as selected by the operator.

7. The charter of claim 6 further comprising:

printer means connected to said arithmetical means for printing in numerical form and for plotting in graphical form the averaged data in the edited or unedited form selected by the operator.

8. The charter of claim 1 further comprising:

arithmetical means connected to said first storage means for calculating the product of substantially concurrent systolic blood pressure and heart rate data.

9. The charter of claim 8 further comprising:

printer means connected to said arithmetical means for printing in numerical form and for plotting in graphical form the calculated product.
