what is the normal blood pressure range
Now a blood pressure of 120/80 is considered normal, and blood pressure readings of 130â139 are considered pre-hypertension. Readings above 140/90 are considered high blood pressure, and the current thinking is that anyone falling into this category should be taking medication to lower blood pressure. blood pressure reading gives two numbers (for example, 140/90). The top number is called the systolic pressure. It is the amount of pressure inside the arteries when the heart contracts. The bottom number is called the diastolic pressure.
