How To Make Pulse Counter
The rhythmical dilation of arteries produced when blood is pumped outward by regular contractions of the heart, especially as palpated at the wrist or in the neck.
The pulse is usually felt just inside the wrist below the thumb by placing two or three fingers lightly upon the radial artery. The examiner’s thumb is never used to take a pulse because its own pulse is likely to be confused with that of the patient. Pressure should be light; if the artery is presse
d too hard, the pulse will disappear entirely. The number of beats felt in exactly 1 minute is the pulse rate.
