Why is a cardiac output calculator useful?
Well, for starters, let’s define just what cardiac output is. Cardiac output is the the amount of blood pumped by the heart per minute. This is a very important value to know, especially if you suffer from cardiovascular disease.
This cardiac output calculator is beneficial by showing you not only what your cardiac output is, but what your cardiac index is as well. This information can be especially important for you if your health is subpar or if you simply want to have more knowledge about your heart’s status quo.
When you engage in exercise, your heart rate and stroke volume increase. When this happens, this also causes your cardiac output to increase. During exercise, there’s a decrease in peripheral resistance mainly due to the dilation of vessels supplying skeletal muscles.
It’s important to note here that the reduction in peripheral resistance is not as great as the increase in cardiac output. This is essentially why blood pressure increases during exercise, regardless of the vessels being dilated. Using a cardiac output calculator allows you to better understand how effectively your heart can pump blood throughout your body to successfully nourish your tissues in a given minute.
What is arterial blood?
Arterial blood is oxygenated blood in the circulatory system that is found in the left chambers of the heart, the lungs, and also in the arteries. This is the blood that is rich in oxygen and nutrients which is used to help fuel and repair working tissues. Blood is oxygenated in the lungs. It then returns to the left atrium through the pulmonary veins. And finally into the left ventricle before it’s pumped throughout the body.
You’ll need to provide your oxygen saturation, oxygen tension, and oxygen concentration in the cardiac output calculator above to yield you the correct results.
What is venous blood?
Venous blood is deoxygenated. Oxygenated blood becomes deoxygenated by using the oxygen to nourish working tissues throughout the body via the circulatory system. Deoxygenated blood is pumped by the right ventricle to the lungs via the pulmonary artery which is divided into two branches, left and right to the left and right lungs.
Just as the case with arterial blood, you’ll need to do the same with venous blood by providing your oxygen saturation, oxygen tension, and oxygen concentration in the cardiac output calculator.
What cardiac index means in a cardiac output calculator
With this cardiac output calculator, you get the benefit of obtaining your cardiac index. What is a cardiac index? Well, in short, a cardiac index is a haemodynamic parameter that relates the cardiac output from the left ventricle in 1 minute to the body’s surface area. Thus, relating heart performance to the size of the individual. This information can be especially important as it gives you a relative parameter to take into consideration as you yield your results from the cardiac output calculator.
All in all, using a cardiac output calculator can be very beneficial for you as it will show you how efficient your heart is at pumping blood per minute. This information is relevant regardless of whether you suffer from cardiovascular disease, have low cholesterol levels, or are a healthy individual who simply desires to learn more about your own heart health.
