—The visualization of the arterial pulse waveform
has been a problem to clinical physicians because normally, the
medic has to imagine the pulse from palpation. But in this work
we provide a simple electronic device, designed and assembled
from elements such as operational amplifiers, resistances, and
commercial capacitors, among others. We use analogic filters
(active and passive), compensators, amplifiers, a common
fototransistor and a light emitting diode as sensor, which is in
contact with a human arterial pulse palpation site (wrist or
neck). In the results it is possible to see a clear signal from an
arterial pulse waveform in an oscilloscope screen. Finally,
remain in the future work to integrate a display to see the
waveform in other devices, also to perform arterial pulse
waveform semiology automatically.
