Blood Presure
Blood pressure is a measurement of the force of blood pushing against the walls of your arteries as your heart pumps blood through your body. It is a vital sign that provides important information about your cardiovascular health.
How Blood Pressure Is Measured
Blood pressure is expressed as two numbers, typically written as a fraction, such as 120/80 mm Hg.
-
Systolic pressure (the top number) is the pressure in your arteries when your heart beats and pumps blood.
-
Diastolic pressure (the bottom number) is the pressure in your arteries when your heart is at rest between beats.
-
The measurement is given in millimeters of mercury (mm Hg).
Blood Pressure Categories
The American Heart Association and other health organizations have established categories for blood pressure readings:
If your systolic and diastolic numbers fall into different categories, your blood pressure category is the higher of the two.
High Blood Pressure (Hypertension)
High blood pressure is a common and dangerous condition because it often has no symptoms. This is why it's sometimes called the "silent killer." Over time, uncontrolled high blood pressure can damage your blood vessels and organs, leading to serious health problems like:
-
Heart attack
-
Stroke
-
Kidney disease
-
Heart failure
The only way to know if you have high blood pressure is to have it measured regularly. If your blood pressure is consistently high, a healthcare provider will likely recommend a combination of lifestyle changes and, in some cases, medication.
Low Blood Pressure (Hypotension)
Low blood pressure is generally considered a reading below 90/60 mm Hg. While a low blood pressure reading may be normal for some people and not cause any problems, a sudden drop can be a sign of an underlying issue. Symptoms of low blood pressure can include:
-
Dizziness or lightheadedness
-
Fainting
-
Blurred vision
-
Nausea
-
Fatigue
If you experience these symptoms, especially if your blood pressure drops suddenly, it's important to consult with a healthcare professional to determine the cause. Very low blood pressure can be dangerous and, in severe cases, can lead to shock.
When to Seek Medical Attention
-
Hypertensive Crisis: If you get a blood pressure reading of 180/120 mm Hg or higher, and you have symptoms like chest pain, shortness of breath, back pain, numbness, vision changes, or difficulty speaking, you should seek immediate emergency medical care.
-
Hypotension: If you have symptoms of shock (such as cold, clammy skin; rapid, shallow breathing; or a weak, rapid pulse), you should call for emergency medical help immediately.
Regularly monitoring your blood pressure is an important step in maintaining your overall health.
OTHER CARDIOVASCULAR FITNESS TESTS
-
3-Minute Step Test:
How to: You'll need a 12-inch high step or sturdy box, a timer or stopwatch, and a metronome app (set to 96 beats per minute).
Step up and down at the metronome's pace for 3 minutes (up-up-down-down).
Immediately after, sit down and count your pulse for one full minute.
What it measures: How quickly your heart rate recovers after exercise, which is an indicator of your cardiovascular fitness. A lower heart rate after exercise generally indicates better fitness.
-
Cooper Test: The Cooper Test is a 12-minute running or walking test designed to measure a person's cardiovascular endurance. See instructions below.
-
1-Mile Walk Test:
How to: Find a flat, safe 1-mile route. Time yourself walking as fast as you can (without running or jogging) over that distance.
What it measures: Aerobic fitness based on the time it takes you to complete the mile.
You can find general fitness level norms based on age and sex.
In conclusion, cardiovascular fitness tests are a vital component of health and fitness assessments. They provide valuable insights into an individual's cardiovascular health, guide training programs, and help in the early detection of potential health issues. By understanding and utilizing various testing methods, individuals and healthcare providers can work together to promote better cardiovascular health and overall well-being. Regular testing and monitoring can lead to improved fitness levels, enhanced athletic performance, and a lower risk of cardiovascular diseases.
