I take it you mean on your blood pressure readings? The bottom number is the pressure the blood is returning to the heart.

blood pressure gradient
When diastolic blood pressure (the lower BP number) is subtracted from the systolic blood pressure (the higher BP number), and the value is 60 or more, there is a widened pulse pressure. With persistently widened pulse pressures, individuals are at increased risk of cardiovascular and cerebrovascular (stroke) events.
systolic and diastolic pressures.
A good blood pressure reading for the average person is Less than 120 for the systolic (top) number and less than 80 for the diastolic (bottom) number). Blood pressures between 140-150 systolic and 90-99 diastolic are considered to be Stage 1 high blood pressure. A systolic reading of 160 or higher and a diastolic of 100 or higher is considered to be Stage 2 High Blood Pressure. Higher numbers than those are considered to be a crisis and can be life threatening.
If your top number is 140 or more then you have very high blood pressure, regardless of your bottom number - your apparatus is faulty
No, you do not have to be a registered nurse to take blood pressures. Many trained healthcare professionals, including medical assistants, nursing students, and even some fitness trainers, can measure blood pressure. However, proper training and understanding of the technique and equipment are essential to ensure accurate readings. Always follow local regulations and guidelines regarding who is authorized to perform such tasks.
