What is an ICU Hemodynamic Calculator?

An ICU hemodynamic calculator helps clinicians assess cardiovascular performance by calculating cardiac output, cardiac index, stroke volume, and mean arterial pressure (MAP). These parameters are critical for managing shock, sepsis, heart failure, and post-operative ICU patients.

Why MAP is Important in ICU?

Mean arterial pressure reflects tissue perfusion. A MAP below 65 mmHg may indicate inadequate organ perfusion and increased risk of shock or organ failure.

Heart Rate

Number of heartbeats per minute.

Stroke Volume

Blood ejected per beat.

Body Surface Area

Used to normalize cardiac output into cardiac index.

Systolic & Diastolic Blood Pressure

Used to calculate MAP and assess perfusion pressure.

Frequently Asked Questions

What is normal cardiac output?

Normal cardiac output in adults ranges from 4 to 8 L/min.

What is normal MAP in ICU patients?

A MAP of 65–100 mmHg is generally considered adequate for organ perfusion.

Who should use this ICU calculator?

Medical students, ICU nurses, residents, and physicians can use this calculator for educational and clinical reference.
