Colloid osmotic pressure (COP) calculator is an assessment tool to calculate the colloid osmotic pressure in patients.
To calculate the colloid osmotic pressure in patients.
Use to calculate the colloid osmotic pressure in order to determine the pressure induced by proteins in blood plasma. Formula: Colloid Osmotic Pressure = (Globulin in g/dL x 1.4) + (Albumin in g/dL x 5.5) Reference ranges: Parameter Normal Low Normal High Globulin 2 g/dL (20 g/L) 3.5 g/dL (35 g/L) Albumin 3.4 g/dL (34 g/L) 5.4 g/dL (54 g/L) COP 23 mmHg 29 mmHg
