Acidosis is a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis a condition in which there is too much base in the body fluids. The kidneys and lungs maintain the balance proper pH level of chemicals called acids and bases in the body. Acidosis occurs when acid builds up or when bicarbonate a base is lost. Acidosis is classified as either respiratory or metabolic acidosis. Respiratory acidosis develops when there is too much carbon dioxide an acid in the body. This type of acidosis is usually caused when the body is unable to remove enough carbon dioxide through breathing.
Acidosis is a process causing increased acidity in the blood and other body tissues i. If not further qualified, it usually refers to acidity of the blood plasma. The term acidemia describes the state of low blood pH, while acidosis is used to describe the processes leading to these states. Nevertheless, the terms are sometimes used interchangeably. The distinction may be relevant where a patient has factors causing both acidosis and alkalosis, wherein the relative severity of both determines whether the result is a high, low, or normal pH.

Written and peer-reviewed by physicians—but use at your own risk. Read our disclaimer. These conditions can be categorized as acidoses or alkaloses and have a respiratory or metabolic origin, depending on the cause of the imbalance. Diagnosis is made by arterial blood gas ABG interpretation. In the setting of metabolic acidosis , calculation of the anion gap is an important resource to narrow down the possible causes and reach a precise diagnosis.

Please consult the latest official manual style if you have any questions regarding the format accuracy. Systemic arterial pH is maintained between 7. The control of arterial CO 2 tension Pa CO 2 by the central nervous system CNS and respiratory system and the control of plasma bicarbonate by the kidneys stabilize the arterial pH by excretion or retention of acid or alkali.
Arterial blood gas analysis is a test most frequently performed on critically ill patients in the emergency room, recovery room and intensive care unit by nursing staff.
Acidosis and Alkalosis
Interpreting an arterial blood gas ABG is a crucial skill for physicians, nurses, respiratory therapists, and other health care personnel. ABG interpretation is especially important in critically ill patients. The following six-step process helps ensure a complete interpretation of every ABG. In addition, you will find tables that list commonly encountered acid-base disorders. Many methods exist to guide the interpretation of the ABG.

respiratory and metabolic, and the metabolic component is judged, calculated, or computed Base deficit or excess--the difference between a patients measured serum Respiratory acid and respiratory acidosis--Carbon dioxide is “respiratory acid” and is the abnormality (ie respiratory alkalosis and metabolic aciosis).
Actual changes in pH depend on the degree of physiologic compensation and whether multiple processes are present. See also Acid-Base Regulation. Causes are. Cause is.
Acidosis and alkalosis describe the abnormal conditions that result from an imbalance in the pH of the blood caused by an excess of acid or alkali base. This imbalance is typically caused by some underlying condition or disease. Normal blood pH must be maintained within a narrow range, typically 7. Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7.
