1. High anion gap metabolic acidosis with appropriate compensation
Critical care clinicianBackground
A patient has acidemia with a low bicarbonate and reduced PaCO₂.
Problem
Determine whether the findings represent high anion gap metabolic acidosis and whether respiratory compensation is appropriate.
How to use
Enter pH 7.20, PaCO₂ 25 mmHg, HCO₃⁻ 10 mmol/L, sodium 140 mmol/L, chloride 104 mmol/L, albumin 4.0 g/dL, and select 1 decimal place.
{"ph":7.2,"paco2":25,"hco3":10,"sodium":140,"chloride":104,"albumin":4,"decimalPlaces":1}Outcome
The tool calculates an anion gap of 26, identifies high anion gap metabolic acidosis, and reports appropriate respiratory compensation by Winter’s formula. The delta ratio is 1.0, consistent with a pure high anion gap metabolic acidosis.
