When taking blood pressure there are two readings, eg. 120/70. The first reading (120) is the systolic blood pressure and the second reading (70) is the diastolic blood pressure. The systolic blood pressure is always higher than the diastol…

How does posture effect a persn’s systolic & diastolic blood pressure, wat r error sources when takin BP?

Q: * what possible factors could make the results of taking blood pressure inaccurate, other than the arm not being at heart level?* what are the average systolic and diastolic pressures for someone when they are standing, sitting, lying down, and upside down?

A: If they have a medical condition such as atrial fibrillation or are hypotensive for whatever reason their blood pressure can drop significantly upon standing or sitting up. However in healthy adults the blood pressure should remain stable at around 120/80 regardless of position. The only sources of error i can imagine is artifact noise created by the environment, the tubes of the stethoscope rubbing together, if the patient is moving their arm or fingers, or if there is clothing around the patients arm (although I debate this theory)

Q: I know that systolic is the top number in the fraction and diastolic is the bottom, but I don’t understand what they mean! I looked it up on the internet but all the explanations don’t make any sense to me. Can someone tell me what they mean in simple terms?

In blood pressure, what is the significance of systolic and diastolic readings?

Q: If readings normally fluctuate throughout the day, depending on what we are doing, what would be considered the normal range? What causes either systolic or diastolic reading rise while the other remain normal?Why do systolic readings vary so much but diastolic hardly at all. For example certain emotional stress such as visiting the GP can send the systolic rocketing and the diastolic read normal.

A: Systolic and diastolic arterial blood pressures are not static but undergo natural variations from one heartbeat to another and throughout the day (in a circadian rhythm). They also change in response to stress, nutritional factors, drugs, disease, exercise, and momentarily from standing up.Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 110 over 70 (written as 110/70). * The top number is the systolic blood pressure reading. It represents the maximum pressure exerted when the heart contracts. * The bottom number is the diastolic blood pressure reading. It represents the pressure in the arteries when the heart is at rest.JNC VI Classification of Hypertension:-Category——-Systolic BP (mm Hg) ————Diastolic BP (mm Hg)Optimal-less than 120 and less than 80.Normal-less than 130 and less than 85.High normal.130 to 139 or 85 to 89.Hypertension Stage 1-140 to 159 or 90 to 99.Stage 2-160 to 179 or 100 to 109.Stage 3- greater than or equal to 180 or greater than or equal to 110.Note:- Ethnol use can increase BP. Cocaine use is a potent effector of hypertension. Smoking increases the risk of hypertension.
