The High Blood Pressure Chart-How to Read The Numbers

Have you ever wondered what the numbers on the high blood pressure chart mean? You will often find the doctors mentioning the systolic and diastolic pressure. The high blood pressure chart helps you figure out the blood pressure level and determine if it is healthy or not.

Hypertension or high blood pressure is a condition that affects the long-term force of the blood against the arteries. The high pressure causes health problems cardiovascular diseases. Knowing both the systolic and diastolic numbers could save your life.

Systolic and Diastolic Blood Pressure Defined

Systolic pressure is created when the heart beats and pushes blood from the arteries to the rest of the body.120 mm Hg is the normal systolic pressure, and anything above 140 is hypertension.

Diastolic pressure is measured when the heart rests, and blood and oxygen flow to the heart. The pressure originating from the heart during the rest causes the diastolic pressure. The normal diastolic pressure is 80 and lower.

Anything above 90 indicates high blood pressure. The number on top is the systolic pressure whole the bottom reading is diastolic.

Normal Blood Pressure

The normal blood pressure is 120/80. The blood pressure changes when we sleep, get excited, or nervous. When you are active, blood pressure increases but returns to normal when one rests.
Age, pregnancy and body size affect the normal blood pressure range. Newborns have a low blood pressure, but that is normal. Teens and adults have the same range.

Abnormal Blood Pressure

Any blood pressure range lower than 120/80mmHg is considered abnormal. People suffering from chronic diseases such as diabetes should keep their blood pressure below 130/80 mm Hg.

How to Measure Blood Pressure

The process is painless and simple. The nurse/doctor uses a small gauge with an inflatable cuff. The cuff will go around the upper. Sometimes, it goes on the wrist or forearm. However, for accurate results always use the upper arm.The High Blood Pressure Char

The nurse will inflate the cuff, and it tightens around the arm. Then, release the cuff slowly till it deflates. The systolic pressure appears at the top, and the diastolic one appears at the bottom.

It is written as 120/80. It is important to get your blood pressure checked regularly. The doctor will evaluate any unusually high or low-pressure readings.

Blood Pressure Ranges and What It Means

The blood pressure readings are classified into four categories ranging from normal to hypertension. The doctor will recommend different treatment plans based on individual blood pressure levels. For best results, doctors will evaluate the average readings based on the pressure reading from 2-3 previous visits.

Normal blood pressure

The systolic pressure should be 120 or less. The diastolic mm Hg should be less than 80. Keep up the good work and maintain a healthy lifestyle.


The systolic pressure should range from 120-139, and the diastolic pressure should range from 80-96. People with pre-hypertension are at risk of developing hypertension unless steps are taken to control the situation. The doctor will recommend the best treatment plan.

High blood pressure stage 1

Individuals with hypertension have a systolic blood pressure of 140-159. The diastolic pressure ranges from 90-99. The doctor may recommend lifestyle change coupled with medications to help manage the condition.

Hypertension Stage 2

Anything above 160 or higher as the systolic pressure and 100 or higher for the diastolic pressure is an indication of high blood pressure stage. The doctor may recommend a lifestyle change and prescribe some medications.

Hypertensive crisis

There are some figures that indicate the patient needs urgent medical care. The pressure reading is over 180 for the systolic pressure and over 110 for the diastolic pressure.

Patients may experience symptoms such as shortness of breath, numbness, and weakness, chest pains, and change of vision.

Which Number Is Important?

Doctors pay attention to the systolic blood pressure as it a risk factor for cardiovascular diseases. The systolic pressure rises steadily with age, and it affects the stiffness of the arteries.

People over 50 suffer the risk of cardiovascular diseases because of the plaque buildup and the increased incidences of cardio and vascular diseases. However, an elevated systolic or diastolic pressure is the only issue used to make a hypertension diagnosis.

    I used to not bother about blood pressure when I was younger. But I think it’s about time I start paying attention to getting blood pressure reading right. With struggles of raising up a kid and financial difficulty, it’s only a matter of time before hypertension catches up. Is there any obvious sign that you’ll feel when your blood pressure rises?
