PPT-Abnormalities in acid-base balance

Many critical illnesses can disturb acidbase balance Acidbase disturbances may indicate an underlying disease or organ damage Accurate interpretation of acidbase disturbances requires the following. Janis Rusin APN, MSN, CPNP-AC. Pediatric Nurse Practitioner. Lurie Children’s Transport Team. Objectives. Discuss the mechanisms for maintaining normal acid-base balance. Define respiratory and metabolic acidosis and alkalosis. Definitions . Strong Acids. HCl. HBr. HI. HNO. 3. HClO. 4. H. 2. SO. 4. Acid: a species that supplies H. +. ions to water. Strong acid: an acid that completely ionizes in water forming an H. +. ion and an anion. Titration. Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. of Salts. Acid-Base Properties of Salts. Type of Salt. Examples. Comment. pH of solution. Cation is from a strong base, anion from a strong acid. KCl, KNO. 3. NaCl. NaNO. 3. Both ions are neutral. Neutral. Diagnosis of acid base balance in diarrhoeic calves. Implementation in practice Dai Grove-White A historical perspective William O ’ Shaughnessy 1831 “I would expect much benefit from the frequently repeated use of the neutral salts by the mouth dissolved in large quantities of tepid water. In severe cases, in which Coakley. 2/27/2014. Quick Review: Acids. Acids are compounds which function as. hydrogen (H+) donors . in biochemical equations/solutes.

This lecture presents the basic concepts of pharmaceutical inorganic chemistry with emphasis on the description, mechanisms and uses of various pharmaceutical products which are clinically used to correct various body disorders. The major topics to be covered are acids and bases, intra and extra cellular electrolytes, the gastrointestinal agents and topical agents frequently employed in the conversion of drugs to chemical forms convenient to their product formulations.. Acid. is defined as a substance which when dissolved in water gives hydrogen ions. (H +) . Examples.. Base is defined as a substance which when dissolved in water gives hydroxyl ions. (OH-) .
