An acid-base diagram for human plasma, showing the effects on the plasma pH when P CO 2 in mmHg or Standard Base Excess (SBE) occur in excess or are deficient in the plasma [23] Acid–base imbalance occurs when a significant insult causes the blood pH to shift out of the normal range (7.32 to 7.42 [16]).
Metabolic acidosis is a serious electrolyte disorder caused by an imbalance in the body's acid-base balance. It can be acute or chronic, and can lead to acidemia, which is defined as arterial blood pH that is lower than 7.35.
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 (7.35 to 7.45). In the fetus, the normal range differs based on which umbilical vessel is sampled (umbilical vein pH is normally 7.25 to 7.45; umbilical artery pH is normally 7.18 to 7.38). [1]
Electrolyte imbalance is an abnormality in the concentration of electrolytes in the body, which can affect various functions and organs. Learn about the causes, symptoms, and treatment of different electrolyte disturbances, such as calcium, chloride, magnesium, phosphate, potassium, and sodium.
As with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H 2 CO 3) and its conjugate base (for example, HCO − 3) so that any excess acid or base introduced to the system is neutralized. Failure of this system to function properly results in acid-base imbalance, such as acidemia (pH < 7.35) and alkalemia ...
A Davenport diagram is a graphical tool to describe blood acid-base chemistry following a respiratory or metabolic disturbance. It shows the relationship between PCO2, bicarbonate and pH, and how they change with different buffers and conditions.
Acidosis is a biological process that increases hydrogen ion concentration in blood or body fluids, lowering pH. It can be metabolic or respiratory, and can be compensated by the lungs or kidneys. Learn about the signs, causes and treatment of acidosis.
Homeostasis is the state of steady internal physical and chemical conditions maintained by living systems. Learn about the components, history, and applications of homeostasis, and see how it regulates variables such as temperature, pH, and blood sugar.
