Did you know that the thing used to measure your blood pressure is called a sphygmomanometer, also known as a blood pressure meter, blood pressure monitor, or blood pressure gauge and is composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner.A mercury or mechanical manometer is used to measure the pressure. This is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded.Manual sphygmomanometers are used in conjunction with a stethoscope.Once you have checked your systolic blood pressure (SBP), your diastolic blood pressure (DBP) and your heart rate per minute (Beats Per Minute BPM), you really should write down your results in the Blood Pressure Monitor Log Book.This way you will have an hourly record of your blood pressure and you will be able to track what is causing it to go high or low.Check before and after a meal to see if there is any difference and then, after consulting with your doctor, see if your diet needs changing.Check first thing in the morning and right before you go to sleep. Check for differences.Keep track in this big, 8.5X11 inch, 150 page Blood Pressure Gauge Book.Perfect book to fill out and bring to your next physician's appointment to show your doctor exactly what your blood pressure is over a long period of time.
