TL;DRAbstract
Data acquisition systems make it very easy to collect huge amounts of data from many sources at once. The real challenge is in data reduction: obtaining useful information from the mass of numbers. As an example, imagine digitizing a blood pressure trace from an arterial catheter at 50 Hz. The tracing would look something like Figure 5.1 and at a heart rate of 88 beats/min there are thirty-four data points per beat. What we really want is the mean, systolic and diastolic pressure for each beat, plus the instantaneous heart rate: four values per beat.
