[Computerized processing, using a Macintosh, of ambulatory arterial pressure measurements collected on a Spacelabs...

The use of the Spacelabs blood pressure recorder has given rise to processing programs running on Apple II and IBM PC computers. The authors have written in M.S. BASIC (2.1) a program who take advantage of graphic abilities and easy manipulation on Macintosh. The software was designed to perform three tasks: Communicating between Macintosh and Spacelabs station using serial interface (RS 232) without requesting specific interface card. Editing a report on two pages: The first is the listing of 96 measurements (one by 15 minutes). The second provides: patient identification, height, weight, diagnosis. Graphic representation of measurements Systolic and diastolic blood pressure (BP) repartition histogram for 24 hours, day and night. Standard deviation and mean of pressure and heart rate (HR) for those periods. A third optionally gives hourly chronogram and diagrams for cumulated BP and HR. Creating a file: 550 records can be stored on a 800 K floppy disk. The file handles: data for each patient (excepted identification). Random access and revision of each parameter is possible.

comparative reports for group patients and patient by patient analysing data with appropriate statistical test (ANOVA and correlation) are done.
