Here are simple estimates of pericardial effusion volume based on echo measurements: - Mild: < 100 mL (echo size < 1 cm) - Moderate: 100-500 mL (echo size 1-3 cm) - Severe: > 500 mL (echo size > 3 cm) To estimate the volume of pericardial effusion (in mL) based on the size measured on echocardiography, you can use the following formula: Volume (mL) = [ (D1 x D2 x D3) / 3 ] x 4 Where: D1, D2, and D3 are the diameters of the effusion (in cm) measured in three different views: - D1: Anteroposterior diameter (measured in the parasternal long-axis view) - D2: Transverse diameter (measured in the parasternal short-axis view) - D3: Inferosuperior diameter (measured in the apical four-chamber view) Note: This formula is an estimate and may not always accurately reflect the actual volume of the effusion. Here are the key points for signs of cardiac tamponade: *Clinical Signs:* 1. *Beck's Triad*: - Hypotension (low blood pressure) - Muffled heart sounds ...
