Understanding Blood Pressure
Before delving into the specifics of how wrist blood pressure monitors work and their accuracy, it’s essential to have a clear understanding of what blood pressure is and why it matters for your health.
Blood pressure refers to the force exerted by circulating blood against the walls of your blood vessels. It is measured in two numbers: systolic pressure and diastolic pressure. The systolic pressure represents the force when the heart contracts and pumps blood into the arteries, while the diastolic pressure is the force when the heart is at rest between beats.
Blood pressure readings are typically given as two numbers, such as 120/80 mmHg. The first number represents the systolic pressure, while the second number represents the diastolic pressure. Blood pressure levels are categorized into different ranges, including normal, elevated, hypertension stage 1, and hypertension stage 2, with varying degrees of severity.
Maintaining a healthy blood pressure is important as high blood pressure, also known as hypertension, puts extra strain on the heart and blood vessels, increasing the risk of serious health problems, such as heart disease, stroke, and kidney disease. On the other hand, low blood pressure, known as hypotension, can cause dizziness and fainting, indicating that organs are not receiving adequate blood supply.
Regular blood pressure monitoring allows individuals to track changes in their blood pressure over time and make necessary adjustments to their lifestyle and treatment plans. It is a vital tool in managing and preventing hypertension.
Now that we have a clear understanding of the significance of blood pressure, let’s explore how wrist blood pressure monitors function and their effectiveness as a monitoring tool.
