The more free H+ ions available for donation, the more acidic the compound. . hassan. objectives. 1. Describe the physiology involved in the acid/base balance of the body.. 2. Compare the roles of PaO2, pH, PaCO2 and Bicarbonate in maintaining acid/base balance.. 3. Review causes and treatments of Respiratory Acidosis, Respiratory Alkalosis, . Many critical illnesses can disturb acid-base balance.. Acid-base disturbances may indicate an underlying disease or organ damage.. Accurate interpretation of acid-base disturbances requires the following:. Acid-base balance.  . * Acids are electrolytes that release hydrogen ions (H+) when they are dissolved in water.. * Bases are electrolytes are release hydroxide ions (OH-) when they are dissolved in water.. 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-) . Examples..
