THE PULSE AND BLOOD PRESSURE
The pulse beat is generally taken at the fron of the wrist wehre the Radial Artery passes into the palm of the hand.
The average rate of the pulse in a healthy adult is 72 beats each minute. There may be a variation of up to five beats per minute (rarely more) within the normal range. In infants and young children the normal rate is faster (up to 100 beats per minute).
To take the pulse, place three fingers along the line of the artery about half an inch in from the thumb side of the lower end of the forearm. Roll the artery undre the fingers until the maximum beat is felt.
(a). The speed whether normal, fast or slow.
(b). The strength wether normal, strong or feeble
(c). The rhythm whether regular or irregular
The pressure of the blood in the arteries is called the blood pressure and is maintained by the force required to push the blood through the capillary section of the circulation. It follows, therefore, that if an artery is cut, blood will spurt out with considerable force, varying according to the size of the artery. The pressure decreases in the small arteries and capillaries owing to their large sectional areas. Blood pressure is therefore, greatest in the arteries, less in capillaries and least in veins.
