Measuring your blood pressure can help you and your doctor prevent or control hypertension and its many complications. Blood pressure readings in the doctor's office may be higher than at other times. The use of home blood pressure monitors can more accurately measure one's overall, or average, blood pressure level. We suggest that persons over age of 40 begin keeping a daily log of their blood pressure readings. Measuring your own pressure is neither expensive nor difficult. It's a good idea to take readings at different times of day, in case there is a difference between morning and evening values. The Blood Pressure Tracker simplifies blood pressure and heart rate data logging. The software automatically saves systolic and diastolic blood pressure, heart rate, and time of measurement. In addition to being a convenient data logger the software is also a valuable tool for blood pressure longitudinal trends analysis. This longitudinal analysis may help you and your doctor decide on the best medicine and help adjust daily drug dosage.
