Is a blood pressure of 302/90 good or bad?
You may be wondering if a blood pressure of 302/90 is considered good or bad or if it's too high, too low, or normal.
According to the American Heart Association, a blood pressure reading of 302/90 would be considered hypertensive crisis. A hypertensive crisis happens when the systolic reading (the top number) is higher than 180 and/or the diastolic reading (the bottom number) is higher than 120.
What is a good blood pressure reading?
According to the American Heart Association, a normal blood pressure reading is lower than 120/80. While there is no specific number for low blood pressure, most experts say blood pressure is too low when it causes symptoms or drops suddenly. In general, though, low blood pressure can be considered anything under 90/60.
More information about a blood pressure reading of 302/90
A blood pressure reading of 302/90 is pronounced "302 over 90." You may also see it written colloquially as 302/90 bp.
In a blood pressure reading of 302/90, 302 is called the systolic number and 90 is called the diastolic number. Systolic refers to the part of the cardiac cycle in which the heart contracts and pumps blood from the chambers into the arteries, and diastolic refers to the part of the cardiac cycle in which the heart relaxes and allows the chambers to fill with blood. You may also hear the systolic and diastolic numbers referred to as the top number and the bottom number.
Systolic and diastolic readings are measured in mmHg, which is a unit of pressure equal to the pressure that can support a column of mercury 1 millimeter high. Hg is the chemical symbol for mercury. For a blood pressure reading of 302/90, you would pronounce it "302 over 90 millimeters of mercury."

Please note that if a field is blank, it's not an accident—it simply means a record doesn't exist for that particular blood pressure. This could be because going forward or backward would create a blood pressure reading that wouldn't make sense, or because that blood pressure simply doesn't exist in our records.

How do you measure blood pressure?
In a doctor's office, blood pressure is traditionally taken manually by a doctor or nurse with a sphygmomanometer. A sphygmomanometer is a medical instrument with an inflatable cuff and pressure meter or dial. The sphygmomanometer is placed snugly around the upper arm and is inflated by hand, and the doctor or nurse listens to the brachial artery with a stethoscope as they gradually reduce the pressure of the cuff. When the whooshing sound of blood is first heard through the stethoscope, the doctor or nurse makes note of the reading on the pressure meter. This indicates the systolic blood pressure reading. When the sound disappears, the reading on the pressure meter indicates the diastolic pressure reading.
Blood pressure can also be taken at home using a number of a digital devices. They typically consist of an inflatable cuff and digital display and simply work by placing the cuff around the upper arm and pressing a button, after which the cuff inflatess, deflates, and displays a reading. The most popular blood pressure machines for home use are made by Omron, Beurer, and Paramed, amongst many others.
