1. Systole is when the ventricles contract and push the blood out through the body. The higher number is the systole pressure. It is when the pressure of the blood pulsating through the arteries equals the pressure of the cuff. Diastole is when the whole heart has a brief period of rest before beginning the next beat. We read this as the lower number in blood pressure.
2. Heart rate is measured with a stethoscope or with fingers. Blood pressure is measured with a blood pressure cuff and a stethoscope.
3. The thumb is not ideal to use because it has its own pulse. The two pulses can be confused and cause an inaccurate reading.
4. The blood pressure cuff works by first increasing the pressure to the point of cutting blood supply to the arm off. After the circulation is cut off you slowly lower the pressure until the blood starts pumping through the arm again and you can hear it. This is the systolic pressure reading. It is when the pressure of the ventricles closing equals the pressure exerted on that artery. Then the diastolic pressure reading is when the heart beat stops being heard. That is when the pressure equals the pressure exerted when the heart relaxes.
