Measuring blood pressure is one of the first things that a doctor would do while treating a patient. It is not used for treating a patient but to find out the ailments or physical problems that somebody might be suffering from. However, a lot of medical students ask their teachers: Why do you need a stethoscope when taking blood pressure?
The answer to this can be simple as well as complex. However, in order to have a basic understanding, the following elements may be taken into account:
1) The heart is responsible for pumping blood throughout the body.
2) The heart is therefore, responsible for the transportation of all sorts of elements to different parts of the body.
3) The extent to which the flow of the blood will be forceful will depend upon the intensity of the way the heart will be pumping.
This can be perceived as one of the most elementary explanations that can be put forth in order to explain Why do you need a stethoscope when taking blood pressure. However, to get into the finer details, the following reasoning may be of some use.
How it works
The rate at which blood flows depends upon how fast the heart pumps it. Therefore, it cannot be wrong to assume that the flow of blood, which is otherwise known as blood pressure, is directly dependent upon the heartbeat. The faster the heartbeat, the higher the blood pressure is going to be.
If we take, for example, the following rationale that a person has high blood pressure but the heartbeat is more or less around average levels. What reasoning should be put forward to explain the high blood pressure that he has? In many cases, other factors such as anxiety or too much salt in the food may be attributed as reasons. However, in order to answer the question, Why do you need a stethoscope when taking blood pressure, here are a few points:
1) Using a stethoscope determines the rate of the heartbeat, or the pulse. Therefore, while measuring the blood pressure and the pulse at the same time, using a stethoscope will make it evident if there is a correlation between the two. If there is, the logical conclusion is to rule out the possibility of anything else as a reason for the high blood pressure. The same argument can be used to explain the converse ~ low blood pressure.
2) It is a known fact among doctors that measuring blood pressure and the pulse simultaneously is effective in determining the primary reasons behind people’s illness. Therefore, using a stethoscope at the same time as measuring blood pressure is one of the elementary lessons that any aspiring doctor is given.
However, for people who are extra curious about the complex reasoning behind such rules, there is no shortage of matter for them to read up on and perform research. That in turn, will improve their knowledge about the particular process instead of merely believing whatever their textbooks and superiors tell them.
