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. One of the main purposes of the test is assessment of acid-base status, which is often disturbed during critical illness. This article is intended to provide an introduction to the physiology of acid-base balance and the many pathological conditions that are associated with disturbance of that balance. It provides nurses and other health professionals, who are less than familiar with the topic, with a basis for understanding how the results of arterial blood gas analysis are applied in the investigation of patients whose acid-base balance is disturbed. Normal cell metabolism depends on the maintenance of blood pH within very narrow limits 7.

Acid-base disorders

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. A summary of these techniques can be found in some of the suggested articles. What is the relationship between the direction of change in the pH and the direction of change in the PaCO 2?

Acidosis and Alkalosis

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. Acidemia is said to occur when arterial pH falls below 7.

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.

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.

The control of arterial CO 2 tension Paco 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. The metabolic and respiratory components that regulate systemic pH are described by the Henderson-Hasselbalch equation:.

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. Compensatory mechanisms begin to correct the pH see table Primary Changes and Compensations in Simple Acid-Base Disorders whenever an acid-base disorder is present.

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. Many conditions and diseases can interfere with pH control in the body and cause a person's blood pH to fall outside of healthy limits. Most of the acid is carbonic acid, which is created from carbon dioxide CO 2 and water.

Беккер достал блокнот. - Итак, начнем с утра. Расскажите мне, что произошло.

 Их слишком много! - воскликнула Соши, выхватив распечатку из рук Джаббы и сунув ее под нос Сьюзан.  - Смотрите. Сьюзан кивнула. Так и есть, примерно через каждые двадцать строк появляется произвольный набор четырех знаков. Сьюзан пробежала все их глазами.

И это понятно, - подумала.  - Никакой вирус Хейла не волнует, он ведь отлично знает, что происходит с ТРАНСТЕКСТОМ. Но Чатрукьян стоял на. - Зараженный файл существует, сэр.

Из пулевого отверстия в виске хлестала кровь - прямо на. Росио попробовала закричать, но в легких не было воздуха. Он вот-вот задавит. Уже теряя сознание, она рванулась к свету, который пробивался из приоткрытой двери гостиничного номера, и успела увидеть руку, сжимающую пистолет с глушителем.

Но чего еще можно было ждать от Танкадо - что он сохранит кольцо для них, будучи уверенным в том, что они-то его и убили.

    acid base disorders are possible: Two metabolic disorders can occur together. One metabolic disorder can occur together with a single respiratory disturbance.
