The kidney is a homeostatic organ that varies the excretion of water, electrolytes, and other hydrophilic molecules to maintain constancy of the composition of the extracellular fluid ECF.

Acid-Base Balance

By convention, scientists refer to hydrogen ions and their concentration as if they were free in this state in liquid water. The pH is calculated as the negative of the base 10 logarithm of this concentration:. Human cells and blood each maintain near-neutral pH. The pH of a solution indicates its acidity or basicity alkalinity. The pH scale is an inverse logarithm that ranges from 0 to anything below 7. Extremes in pH in either direction from 7. The pH in cells 6.

An important property of blood is its degree of acidity or alkalinity. The acidity or alkalinity of any solution, including blood, is indicated on the pH scale. The pH scale, ranges from 0 strongly acidic to 14 strongly basic or alkaline. Blood is normally slightly basic, with a normal pH range of about 7. Usually the body maintains the pH of blood close to 7. A doctor evaluates a person's acid-base balance by measuring the pH and levels of carbon dioxide an acid and bicarbonate a base in the blood.

Acid—base imbalance is an abnormality of the human body's normal balance of acids and bases that causes the plasma pH to deviate out of the normal range 7. In the fetus , the normal range differs based on which umbilical vessel is sampled umbilical vein pH is normally 7. An excess of acid is called acidosis or acidemia and an excess in bases is called alkalosis or alkalemia. The process that causes the imbalance is classified based on the cause of the disturbance respiratory or metabolic and the direction of change in pH acidosis or alkalosis. This yields the following four basic processes:.

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. Even relatively mild excursions outside this normal pH range can have deleterious effects, including reduced oxygen delivery to tissues, electrolyte disturbances and changes in heart muscle contractility; survival is rare if blood pH falls below 6. The mechanism which overcomes this problem and serves to maintain normal blood pH i.

Your blood needs the right balance of acidic and basic alkaline compounds to function properly. This is called the acid-base balance. Your kidneys and lungs work to maintain the acid-base balance. Even slight variations from the normal range can have significant effects on your vital organs. Acid and alkaline levels are measured on a pH scale. An increase in acidity causes pH levels to fall. An increase in alkaline causes pH levels to rise.

The kidneys help maintain the acid—base balance by excreting hydrogen ions into the urine and reabsorbing bicarbonate from the urine. Urine testing is important because it can detect acid—base imbalances. For instance, uncontrolled diabetes results in highly acidic urine. If the diabetes remains uncontrolled, the kidneys could become over-stressed and malfunction, which could lead to coma or death. Within the human body, fluids such as blood must be maintained within the narrow range of 7. Outside that range, pH becomes incompatible with life; proteins are denatured and digested, enzymes lose their ability to function, and the body is unable to sustain itself. To maintain this narrow range of pH the body has a powerful buffering system.

The Kidney in Acid-Base Balance

Согласно расписанию, в полночь должен был заступить на двойную смену новый сотрудник по имени Зейденберг. Чатрукьян еще раз обвел глазами пустую лабораторию и нахмурился.  - Где же он, черт возьми.

Беккер открыл конверт и увидел толстую пачку красноватых банкнот. - Что. - Местная валюта, - безучастно сказал пилот. - Я понимаю.  - Беккер запнулся.

Среднее время, потраченное на один шифр, - чуть более шести минут. Потребление энергии на среднем уровне. Последний шифр, введенный в ТРАНСТЕКСТ… - Она замолчала. - Что .

Джабба понимал, что ВР текущего кризиса со всей наглядностью объяснит то, что он хотел сказать. - ВР! - крикнула Соши, усаживаясь за компьютер в задней части комнаты.

Я вызвал скорую. Беккер вспомнил синеватый шрам на груди Танкадо. - Быть может, искусственное дыхание делали санитары.

От него не ускользнула ирония ситуации: он получал возможность работать в самом сердце правительства страны, которую поклялся ненавидеть до конца своих дней. Энсей решил пойти на собеседование. Сомнения, которые его одолевали, исчезли, как только он встретился с коммандером Стратмором. У них состоялся откровенный разговор о его происхождении, о потенциальной враждебности, какую он мог испытывать к Соединенным Штатам, о его планах на будущее. Танкадо прошел проверку на полиграф-машине и пережил пять недель интенсивного психологического тестирования. И с успехом его выдержал. Ненависть в его сердце уступила место преданности Будде.

The lungs partially compensate for acidosis or alkalosis through increased or decreased excretion of CO 2 in a matter of minutes.

interpreting acid-base balance requires simultaneous mea- surements of arterial pH and plasma electrolytes, as well as knowledge of compensatory physiologic.
