Cardiovascular Responses to Submaximal Exercise
Why can't you hear these sounds before the cuff is inflated?
There is not enough pressure on the artery.
The cuff is there is dramatically slow down the blood flow. In order to hear the
sounds, blood flow must be stopped, then when pressure is slowly released, the
blood rushes through the vein resulting in the thumps and taps. If blood pressure was measured at the level of a subject's calf rather than at the
of the upper arm, would you expect the blood pressure readings to be different?
You would expect the blood pressure readings to be higher due to the nature of
greater elasticity of arteries around the calf. The ABPI (ankle brachial pressure
index) also shows that pressure at the ankles should have higher pressure than
the arm. Describe four sources of error when recording blood
