Drains

Colin had joked with the Doctor about doing a spreadsheet with my drainage. When we went to the appointment on Monday where we were told that the drains were staying in for another few days, he gave us a hard time about the messy hand-written sheet we had. The chart is Colin's stab with an excel spreadsheet and a linear fit.

I managed to put all the data points in MATLAB with relative times and also calculated the drainage rate for each interval. I used MATLAB's Polyfit function to fit a second degree polynomial to each set of data, just for grins.

Surprisingly, the Doctor said he has just had another patient diagnosed with angio-sarcoma of the breast. Primary angiosarcoma should be a once-a-career finding for a surgeon, so to have two within two months is definitely an outlier.
