Joe's Blood Pressure Data

The following graphs were produced by a computer program that helps me track my blood pressure and heart rate as measured by my Omron HEM-712C Digital Blood Pressure Monitor. I save the readings on my handheld and upload them to the astronomy network. (for processing details see below)

Heart Rate

(Some technical details: The program I've written is in the IDL computer programing language. Click here to see a copy of my IDL code and feel free to email me at joehall@pobox.com if you have any questions (about input formats, auxillary files, etc.). I use a command-line/ batch-mode image processing program (ImageMagick) to get from the program output to what you see above)
