decreased bicarbonate‚ or HCO3. Diabetic Acidosis Diabetic acidosis happens when there is too much of the acid known as ketones in the body due to diabetes. A diabetic may not have enough insulin to break down blood sugar‚ so the body uses fat to digest the sugars. Ketones are the byproduct of this alternative process. Blood gases would show a pH lower than 7.4‚ low bicarbonate levels‚ and a low PcO2. Hyperchloremic Acidosis Hyperchloremic acidosis is caused by too much sodium bicarbonate in the

is due to the pressure build-up as the carbon dioxide gas is produced. Describing the Chemical Reaction between Baking Soda and Vinegar Baking soda‚ a pure chemical called sodium bicarbonate‚ has the chemical formula: NaHCO3 When dissolved in water baking soda separates into sodium (Na+) and bicarbonate ions (HCO3- ): NaHCO3 ---> Na+(aq) + HCO3-(aq) Vinegar‚ a weak (5%) solution of acetic acid in water‚ partially dissociates into hydrogen ( H+) and acetate ions (CH3COO-): CH3COOH

Arterial Blood Gas Interpretation (ABG) Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2)‚ carbon dioxide (PaCO2)‚ and the pH of an arterial blood sample. Oxygen content (O2CT)‚ oxygen saturation (SaO2)‚ and bicarbonate (HCO3-) values are also measured. A blood sample for ABG analysis may be drawn by percutaneous arterial puncture from an arterial line. The ABG analysis is mainly used to evaluate gas exchange in the lungs. It is also used to assess integrity of

and carving details become rounded‚ gradually. Black crust forms on sheltered buildings and monuments. A classic buffer is a combination of a weak acid and its conjugate salt; for instance‚ carbonic acid (H2CO3) and sodium bicarbonate (NaHCO3)‚ or even sodium bicarbonate and calcium carbonate. In any buffer system‚ the boost in [H+] increases the reaction rate H+ + salt => weak acid and takes some H+ out of circulation. As it does so‚ it increases weak acid concentration‚ so the reverse reaction
