The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide concentration decides respiratory alkalosis or respiratory acidosis. Normally arterial blood gas analysis are used to assess the acid-base balance.
Upon systematic reviewing of the given case study it is noted that the PaO2 and PaCO2 are within normal limits, indicates that patient is not hypoxemic, still need to continue monitoring of oxygen saturation. The increased pH level of 7.5 indicates alkalosis. The next step is to evaluate PaCO2.Since lung regulates this, its …show more content…
Another treatment plan for metabolic alkalosis is by replacement of electrolytes, plasma volume. , histamine -2 receptor blockers to prevent further gastric acid loss severe case alkalosis can be corrected by dilute (0.1 N) hydrochloric acid or ammonium chloride, mechanical hypoventilation, low acetic acid hemodialysis. Supportive measures include provision of oxygen, monitoring and observation for further development of complication such as depression of ventilation and myocardial perfusion
