How To Take Blood Pressure
By Leeanne Utiger
Many people would not have any idea on how to take blood pressure, and yet knowing how to take a blood pressure reading could prove to be very handy at times. This article will go into detail on how you too can learn to take blood pressure.
When you learn how to take blood pressure you will gain knowledge of how exactly a medical professional also takes a persons blood pressure. On learning how to take blood pressure you will find out that the person whos blood pressure is being taken needs to be seated first. This person will rest their arm on a level table. On discovering facts about taking a persons blood pressure you will learn that it is of utmost importance for the brachial artery to be level with the heart. This is why the person whos blood pressure is being taken has to rest their arm on a level table.
You will find out when learning how to take a blood pressure that a cuff is placed around the persons upper arm. To be more precise, the cuff is placed just above the elbow. A stethoscope is then placed in the hollow of the elbow. You will learn how by placing the stethoscope in the hollow of the elbow is in fact placing it over the brachial artery.
You are now ready to get to the next stage on how to take a blood pressure. You will discover how you have to then pump up the arm cuff to a certain pressure. This is generally about 180mmHg. You will learn how the pressure is in fact compressing the brachial artery, which will in turn make the artery collapse.
You will then learn how to slowly release the pressure from the cuff. Once the pressure is released, blood flow resumes which will create vibrations up against the artery walls. You will also learn how these vibrations create noise which can be heard through the stethoscope which has been placed in the hollow of the elbow.
You will discover how the noises cease to be heard once a certain amount of pressure has been released. You will also learn how there are in fact 5 phases to taking a blood pressure. The varying noises you hear while deflating the arm cuff will illustrate to you which phase you are while taking a blood pressure.
By the time you learn how to recognise phase 4 when taking a blood pressure, you will be able to anticipate that you have almost finished taking a blood pressure. Phase 4 is recognised by muffled sounds, while during stage 5 there will be no noises or sounds at all. You will learn how this indicates to you that the blood flow has now returned to normal and that it is time to carefully take off the blood pressure arm cuff. You will also learn how the blood pressure cuff at this stage has become completely deflated.
That is the basic knowledge you will need to know about how to take a blood pressure. If you need to learn more about how to take a blood pressure, then I suggest you talk to a medical professional for further advice regarding how to take a blood pressure.
