Pathophysiology of acid base balance

What is acid-base balance? Your blood needs the right balance of acidic and basic alkaline compounds to function properly.

Pathophysiology of acid base balance

Diagnosis[ edit ] Although blood gas sampling is not always essential for the diagnosis of acidosis, a low pH in either a venous or arterial sample does support the diagnosis.

If the pH is low under 7. If the patient has other coexisting acid-base disorders, the pH may be low, normal or high in the setting of metabolic acidosis. If a setting of a cause for metabolic acidosis being noted in the patient's history, a low serum bicarbonate indicates metabolic acidosis even without measurement of serum pH.

Other tests relevant in this context are electrolytes including chlorideglucosekidney functionand a full blood count. Urinalysis can reveal acidity salicylate poisoning or alkalinity renal tubular acidosis type I.

In addition, it can show ketones in ketoacidosis. To distinguish between the main types of metabolic acidosis, a clinical tool called the anion gap is considered very useful.

It is calculated by subtracting the sum of the chloride and bicarbonate levels from the sum of the sodium and potassium levels.

As sodium is the main extracellular cation, and chloride and bicarbonate are the main anions, the result should reflect the remaining anions. An elevated anion gap i. As the differential diagnosis is made, certain other tests may be necessary, including toxicological screening and imaging of the kidneys.

It is also important to differentiate between acidosis-induced hyperventilation and asthma ; otherwise, treatment could lead to inappropriate bronchodilation. This intervention, however, has some serious complications in lactic acidosis, and in those cases, should be used with great care.An acid is a substance that can donate hydrogen ions (H+), and a base is a substance that can accept H+ ions, regardless of the substance’s charge.

Essential for NCLEX-RN® preparation, course, and competency review, this volume provides. a complete concentrated outline of fluids, electrolytes, & acid—base balance.

Nov 10,  · Rhabdomyolysis (literally, “dissolution of skeletal muscle”) is a syndrome caused by injury to skeletal muscle and involves leakage of large quantities of potentially toxic intracellular contents into plasma.

First described in the victims of crush injury during World War II, it is a final pathway of diverse processes and insults. Acid-Base Balance: Ketoacidosis Diabetic acidosis, or ketoacidosis, occurs most frequently in people with poorly controlled diabetes mellitus.

When certain tissues in the body cannot get adequate amounts of glucose, they depend on the breakdown of fatty acids for energy. Patho Wk 5: Ch. 3 Part 2 - 1 ACID/BASE BALANCE Objectives Differentiate between metabolic/respiratory acidosis and metabolic/respiratory alkalosis.5/5(1).
