Systemic Vascular Resistance(SVR) Calculator

Free SVR Calculator | Check Systemic Vascular Resistance Fast

Our SVR calculator is a reliable tool designed to help doctors, medical students, & researchers estimate systemic vascular resistance (that’s how hard it is for blood to move through your body). All you need to do is simply type in the value of Mean Arterial Pressure (MAP), Central Venous Pressure (CVP), & Cardiac Output (CO). The calculator will then determine SVR right away. That number helps doctors understand how blood is flowing & working in the body.

What is Systemic Vascular Resistance (SVR)?

SVR is how hard it is for blood to move through your body. Blood leaves the heart, travels around, & comes back. It tells us how much work the left ventricle has to do to push blood out. 

SVR formula: SVR = [(MAP – CVP) × 80] / CO

Its standard unit is dynes·sec·cm⁻⁵.

Doctors who deal with really sick patients, heart problems, or surgery use SVR all the time. It helps them know how well the heart is pumping.

Normal SVR Range

• Normal SVR range: 700–1600 dynes·sec·cm⁻⁵
• Low SVR (<700): May indicate septic shock, vasodilation, or adrenal insufficiency.
• High SVR (>1600): Can signal vasoconstriction, hypovolemia, or hypertension.

Doctors check SVR values to figure out conditions like cardiogenic shock, severe infections, or volume depletion. 

Why Use Our SVR Calculator?

• Accuracy

It delivers an accurate SVR value every time, so you don’t need to worry. 

• Efficiency

Our SVR calculator works fast, which is really helpful in clinical settings like the ICU. 

• Clarity

It tells you the result in numbers & shows if it’s in the normal range.

• Educational Value

It’s also a good learning tool for students who want to practice SVR math & compare it with another measure called Pulmonary Vascular Resistance (PVR).

Clinical Importance

SVR is an important number that tells us about your cardiovascular health. When doctors check SVR, they can change treatments to fit the patient better. They can also alter medicines & see how well someone is doing with tough problems like septic shock, cardiogenic shock, or hypertension. 

Our systemic vascular resistance calculator gives quick & accurate SVR results. This helps doctors make smart choices fast when caring for patients.
