ANATOMY

Detailed explanation-1: -The second number is the diastolic blood pressure which indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats. Anything 140/90 or above is considered a high blood pressure reading, which could be a diagnosis of hypertension.

Detailed explanation-2: -The diastolic pressure of an adult should typically be 60–80mm Hg, and if the number goes above this, it’s considered hypertension. However, if your blood pressure goes over 180/120mm Hg, this is dangerous, and you should seek medical attention immediately.

Detailed explanation-3: -Blood pressure readings are given in two numbers. The top number is the maximum pressure the heart exerts while beating (systolic pressure). The bottom number is the amount of pressure in the arteries between beats (diastolic pressure).

Detailed explanation-4: -However, isolated diastolic hypertension (IDH) occurs when your systolic blood pressure is normal, and only your diastolic blood pressure is high (over 80 mm Hg). IDH is an uncommon type of hypertension, accounting for less than 20% of all hypertension cases.

Detailed explanation-5: -Acute meal ingestion, caffeine or nicotine use can all affect BP readings, leading to errors in measurement accuracy. If the patient has a full bladder, that can lead to an error in systolic BP of up to 33 mm Hg, and the white-coat effect can have an error of up to 26 mm Hg.
