SUSPECTED ACID-BASE DISTURBANCE

SUSPECTED ACID-BASE DISTURBANCE Suspected Acid-Base Disorder Normal pHAcidemia(pH < 7.35) Respiratory Acidosis (pCO2 > 40 mmHg) Methanol Uremia Diabetic Ketoacidosis Propylene Glycol Isoniazid Lactic Acidosis Ethylene Glycol Acetylsalicylic Acid Metabolic Acidosis (HCO3 < 24mmol/L) HCO3 : CO210:10 Renal Gastrointestinal (diarrhea) Alkalemia (pH > 7.45) Metabolic Alkalosis (HCO3 > 28mmol/L) HCO3 : CO212:10 Respiratory Alkalosis (pCO2 < 35 mmHg) Normal Arterial Blood Gas Mixed Acid-Base Disorder Anion GapNon-Anion Gap Acute HCO3 : CO21:10 Chronic HCO3 : CO23:10 Acute HCO3 : CO22:10 Chronic HCO3 : CO24:10 Diagnosis of Mixed Metabolic Disorders in Patients with Metabolic Acidosis:Anion Gap Not Increased Non-Anion Gap Acidosis Alone? Anion Gap = ?HCO3 Anion Gap Acidosis Alone ? Anion Gap < ?HCO3 Mixed Anion Gap Acidosis + Non-Anion Gap Acidosis?Anion Gap > ?HCO3 Mixed Anion Gap Acidosis + Metabolic Alkalosis
