Acid Base Balance Kidneys are the primary organ responsible for excreting acid and regulating electrolyte balance. Lungs regulate acidity by increasing the rate of respiration which results in excreting higher levels of CO2. This is the most efficient way of maintaining acid/base balance, especially in the short-term.

Metabolic alkalosis Compensation for metabolic alkalosis occurs mainly in the lungs, which retain carbon dioxide (CO2) through slower breathing, or hypoventilation (respiratory compensation). CO2 is then consumed toward the formation of the carbonic acid intermediate, thus decreasing pH. Respiratory compensation, though, is incomplete.

Acidosis Acidosis occurs when your kidneys and lungs can’t keep your body’s pH in balance. Many of the body’s processes produce acid. For instance, your lungs and kidneys can usually compensate for slight pH imbalances, but problems with these organs can lead to excess acid in your body. The acidity of your blood is measured by determining its pH. A lower pH means that your blood is more acidic, while a higher pH means that your blood is more basic. The pH of your blood should be around 7.4. According to the American Association for Clinical Chemistry (AACC), acidosis is characterized by a pH of 7.35 or lower.

- Alkalosis (alkalemia) occurs when the pH rises above 7.45. A primary respiratory problem is determined if the PaC02 is less than 35mmHg(alkalosis) or greater than 45 mmHg(acidosis). A primary metabolic problem is when the HC03 is less than 22mEq/L (acidosis) or greater than 26mEq/L(alkalosis).

Background Background. Respiratory alkalosis is a disturbance in acid and base balance due to alveolar hyperventilation. Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO 2).n turn, the decrease in PaCO 2 increases the ratio of bicarbonate concentration to PaCO 2 and, thereby, increases the pH level, thus the descriptive term of respiratory alkalosis.

How would you expect this to affect blood ph and respiratory rate and is this a state of acidosis or alkalosis? When the pH decreases to below 7.35 an acidosis condition is present. Acidosis means that the hydrogen ions are increased and that pH and bicarbonate ions are decreased. A greater number of hydrogen ions are present in the blood than can be absorbed by the buffer systems.Alkalosis results when the pH is above 7.45.This condition results when the buffer base (bicarbonate ions) is greater than normal and the concentration of hydrogen ions are decreased. greater number of hydrogen ions are present in the blood than can be absorbed by the buffer systems. Alkalosis results when the pH is above 7.45. This condition results when the buffer base (bicarbonate ions) is greater than normal and the concentration of hydrogen ions are decreased.

Respiratory Alkalosis Normally, these two gases are kept in balance by the respiratory system. Respiratory alkalosis occurs when carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. This condition is basically the opposite of respiratory acidosis, when the blood becomes too acidic.reating the condition is a matter of raising carbon dioxide levels in the blood. The following strategies and tips are useful for respiratory alkalosis caused by overbreathing due to panic and anxiety: 1  Breathe into a paper bag. 2  This is a very simple strategy. 3  It can also be very effective.

The Effects of Carbon Dioxide in the Bloodstream Increase in Acidity. CO2 is an important source of acid in the blood. This is because an enzyme called carbonic anhydrase rapidly converts CO2 and water into a substance called carbonic acid (H2CO3), which in turn can rapidly turn into HCO3- and free hydrogen ions (H+). pH is a measurement of these free hydrogen ions.

Respiratory acidosis In chronic respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range, with a normal blood pH (7.35 to 7.45) or near-normal pH secondary to renal compensation and an elevated serum bicarbonate (HCO3− >30 mm Hg).

- Alkalosis results when the pH is above 7.45. This condition results when the buffer base (bicarbonate ions) is greater than normal and the concentration of hydrogen ions are decreased. Both acidosis and alkalosis can be of two different types: respiratory and metabolic.

2.3 Respiratory Regulation -continued The peripheral chemoreceptors and the central chemoreceptors both contribute to causing the hyperventilation (Kussmaul respirations) that accompany metabolic acidosis. This increase in ventilation will lower arterial pCO 2 and this will be sensed by the central and peripheral chemoreceptors and ventilation will be inhibited. Changes in CSF [HCO 3] will occur over about 12 to 24 hours and will return CSF pH towards normal.

Respiratory Physiology - HIGH LIGHTED CARDS ONLY The respiratory system can regulate the pH level of the b…lood by the depth and rate of ventilation. By increasing the rate and depth of ventilation, the respiratory system will decrease the amount of CO2 in the blood which will decrease the amount of carbonic acid in the blood. That will increase the blood pH.

Respiratory Alkalosis When you inhale, you introduce oxygen into the lungs. When you exhale, you release carbon dioxide, which is a waste product. Normally, the respiratory system keeps these two gases in balance. Respiratory alkalosis occurs when carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. When the blood becomes too acidic, respiratory acidosis occurs. Hyperventilation is typically the underlying cause of respiratory alkalosis. Hyperventilation is also known as overbreathing. Someone who is hyperventilating breathes very deeply or rapidly.

Alkalosis The kidneys and lungs maintain the proper balance (proper pH level) of chemicals, called acids and bases, in the body. Decreased carbon dioxide (an acid) or increased bicarbonate (a base) level makes the body too alkaline, a condition called alkalosis.

Acid-Base BalanceTerminology The body maintains the blood at pH 7.4, which is about 0.4 pH units more alkaline than the intracellular pH (Reeves and Rahn, 1979). This is equivalent to a 2.5-fold difference in concentration: extracellular - 40 nMol/L; intracellular - 100 nMol/L.

- The two major types of acidosis are respiratory acidosis and metabolic acidosis. Factors that increase carbon dioxide, also increasing the concentration of carbonic acid (the respiratory acid), cause respiratory acidosis. Metabolic acidosis is due to an abnormal accumulation of any other acids in the body fluids or to a loss of bases, including bicarbonate ions.

CO2, Blood pH and Respiratory Alkalosis: Causes and Effects Blood pH is tightly regulated by a system of buffers that continuously maintain it in a normal range of 7.35 to 7.45 (slightly alkaline). Blood pH drop below 7 can lead to a coma and even death due to severe acidosis. This causes depression of the central nervous system. High blood pH (above 7.45) is called alkalosis.

- The amount of carbon dioxide exhaled, and consequently the pH of the blood, increases as breathing becomes faster and deeper. By adjusting the speed and depth of breathing, the brain and lungs are able to regulate the blood pH minute by minute.

Background Background. Respiratory alkalosis is a disturbance in acid and base balance due to alveolar hyperventilation. Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO 2).espiratory alkalosis can be acute or chronic. In acute respiratory alkalosis, the PaCO 2 level is below the lower limit of normal and the serum pH is alkalemic. In chronic respiratory alkalosis, the PaCO 2 level is below the lower limit of normal, but the pH level is relatively normal or near normal.

- Chemical buffers, such as hemoglobin, may resist this shift in pH. At the same time, increasing concentrations of carbon dioxide and hydrogen ions stimulate the respiratory center, increasing breathing rate and depth and thereby lowering carbon dioxide concentration.

USING THE ACID - BASE MAP TO ANALYZE BLOOD GASES The HCO3 is the compensation for this acidosis and has pulled the pH back into the normal range :A COMPENSATED RESPIRATORY ACIDOSIS pH = 7.35CO2 = 25HCO3 = 13 Another compensated blood gas with a pH in the normal range.here are also many non-renal causes of changes in HCO3 like keto-acidosis, lactic acidosis and NG suction, but kidneys are the main controllers of HCO3. More HCO3 means less acid and a higher pH. Less HCO3 means more acid and a lower pH. Normal HCO3 is 24 mEq with a normal range from 22 to 26 mEq.

Pulmonary Disease in the Elderly In particular the lungs interact closely with the kidneys in order to maintain the blood pH within the narrow range (7.34–7.45) needed to sustain life. Therefore a change in one of these organ systems will affect the other as the emunctories work to maintain homeostasis.
