What are the different types of blood pressure measuring devices?

High blood pressure or hypertension is one of the prevalent medical issues that many people struggle with in the world. It is estimated that almost 90% of people have the risk of developing hypertension. So, even if a person doesn't develop high blood pressure by middle age, his/her chances of developing one by the time he/she reaches 55 to 65 are higher. 


But thankfully, medicine has evolved leaps and bounds and has a solution for various health concerns. 


So, in today's blog, we will take a look at the instruments that help in measuring blood pressure. 


But before that, let's understand Blood Pressure. 


Blood pressure is a force that the circulating blood applies on the walls of the blood vessels. This pressure decreases when the blood flows through various organs like capillaries, arteries, veins, and arterioles. 


In general terms, blood pressure is referred to as arterial pressure. 


Arterial pressures can be measured either invasively or non-invasively. For the invasive option, the patient needs to visit the hospital.


What are the types of Blood Pressure Simulators?


The types of Blood Pressure Simulators include:


Non-invasive measurement:

With Non-invasive auscultatory and oscillometric measurement, measuring the blood is simple and quicker than invasive measurement.


This process requires less expertise in fitting and have almost zero complications. And since it causes no pain or unpleasantness, many patients prefer this method. 


However, when it comes to measuring accuracy, one can expect systematic differences in the numerical results. 


That is why NIBP Simulators are used for routine monitoring or examinations. 


Palpation methods:

With the palpation method, the professionals can obtain a rough estimation of the minimum systolic value. The palpation of radical pulse specifies a minimum blood pressure of 80 mmHg. The femoral pulse defines at least 70 mmHg, and the carotid pulse specifies a minimum of 60 mmHg. 


To obtain an exact value of systolic blood pressure, one can opt for a sphygmomanometer when the palpation of radial pulse returns. 


Even the diastolic pressure that is the minimum pressure in the arteries that occur near the end of the cardiac cycle, can be measured using this method. 


Auscultatory methods:

The auscultatory method is a prevalent method where both a stethoscope and a sphygmomanometer are used to determine the blood pressure. The process comprises placing the inflatable cuff over the arm just parallel to where the heart is situated. 


The mercury nanometer is attached to the inflatable cuff gives an accurate result without the need for calibration. 


The clinical professional then proceeds to repeatedly squeeze the rubber bulb until the artery is blocked. The examiner then proceeds to listen to the brachial artery at the elbow using a stethoscope while slowly releasing the pressure. And when the blood starts to flow in the artery, you can listen whooshing sound. The pressure at which this sound is initially heard is termed as systolic blood pressure. The cuff pressure is released until no sound is produced at the diastolic arterial pressure. 


Oscillometric methods:

The oscillometric method is used for long-term measurement as well as in general practice. The equipment has the same functionality as the auscultatory method, but it has an electric sensor fitted on it that detects the blood flow, meaning there is no need for a stethoscope. 


The calibration needs to be checked routinely to maintain the accuracy of the device.


In this method, the inflatable cuff fitted on the upper arm is automatically inflated using an electrically operated pump and valve. 


This method requires fewer skills than Auscultatory method, meaning even an undertrained staff can perform the task. 

And the term Non-Invasive Blood Pressure Simulator is sometimes used to describe oscillometric monitoring equipment.
