Estimates pericardial effusion size from echocardiographic diastolic echo-free space, calculates hemodynamic tamponade risk using Beck triad and respiratory variation, and indicates pericardiocentesis urgency.
BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).
BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

Each component has a specific meaning:
Note: Interpret the pericardial tamponade risk result against the clinical thresholds and context described above.
Enter the echocardiographic diastolic echo-free space, calculates hemodynamic tamponade risk for the patient or scenario you are assessing. Estimates pericardial effusion size from echocardiographic diastolic echo-free space, calculates hemodynamic tamponade risk using Beck triad and respiratory variation, and indicates pericardiocentesis urgency. Use the pericardial tamponade risk result to inform your clinical assessment.
