 Today, I will demonstrate you how we can measure the blood pressure. We will also check the effect of exercise on blood pressure. Dear students, first of all, I will give you a brief introduction of blood pressure. As the heart beats, the blood poured through the arteries cause a rise in pressure caused systolic pressure followed by a decrease in pressure as the heart ventricles prepare for the next beat. This lower pressure is called as diastolic pressure. We can measure blood pressure using an instrument known as Sevegmo Manometer. Dear students, according to guidelines of Centre of Disease Control and Prevention Authentic Source that normal blood pressure should be below 120 by 80 mmHg. This includes a systolic pressure reading under 120 mmHg and diastolic pressure under 80 mmHg. To measure blood pressure, we use an instrument called Sevegmo Manometer. This device composed of an inflatable cup which is wrapped around the arm, a measuring device which indicates the pressure of a bulb to inflate the cup, a valve to release the air. We use a stethoscope to listen to the sound of arterial blood flow. First of all, use a properly sized blood pressure cuff. The length of the cuff's bladder should be at least equal to 80% of the circumference of upper arm. Wrap the cuff around the upper arm with the cuff's lower edge 1 inch above the anticovital fossa. Now lightly press the stethoscope's bell over the brachial artery just below the cuff's edge. Now, rapidly inflate the cuff to 180 mmHg, release air from the cuff at a moderate rate. Listen with the stethoscope and simultaneously observe the Sevegmo Manometer. The first knocking sound is the subject systolic pressure. When the knocking sound disappears, that is the diastolic pressure. The subject has normal blood pressure which is 120 by 80 mmHg. Dear student, now we will check the effect of exercise on the blood pressure. For this, ask the subject to exercise for about 30 minutes. We will check the blood pressure after exercise. Dear student, now the subject has high blood pressure which is 130 by 90 mmHg. Now you can note the difference between normal blood pressure and the blood pressure after exercise. There are different precautionary measures while taking blood pressure using the Sevegmo Manometer. First, use a large cuff on obeys and heavily muscles subjects. Second, for pediatric patients use a smaller size cuff. Third, in pediatric patients, the lower blood pressure may indicate the presence of hypertension. Number 4, don't place the cuff over clothing. And number 5, always flex and support the subject's arm. Dear student, this experiment makes you understand the importance of getting accurate blood pressure measurements so that you have clear pictures of your risk factor for heart diseases and stroke.
