What happens to blood pressure when it is measured inaccurately?

When blood pressure is measured inaccurately, it can produce false readings. This could be due to various factors, such as using an improperly calibrated sphygmomanometer, incorrect cuff size, or improper technique during measurement. As a result, the readings may not reflect the true blood pressure of the individual. For example, if the cuff is too small, it may lead to an overestimation of blood pressure, while a cuff that is too large may underestimate it. Therefore, accurate measurement is crucial for diagnosing conditions like hypertension or hypotension and for making informed clinical decisions. Being aware of the potential for false readings emphasizes the importance of proper measurement techniques in clinical practice.
