A decrease in base (ie cheap 16mg atacand mastercard, [HCO −]) is termed a base deficit cheap atacand 4mg fast delivery, and an increase in base is termed a base excess. The primary causes of acid–base disturbances are abnormalities in the respira- tory system and in the metabolic or renal system. As from the Henderson–Hasselbalch equation, a respiratory disturbance leading to an abnormal pCO2 alters the pH, and sim- ilarly a metabolic disturbance altering the [HCO −]changes the pH. Any primary disturbance in acid–base homeostasis invokes a normal compensatory response. A primary metabolic disorder leads to respiratory compensation, and a pri- 8 mary respiratory disorder leads to an acute metabolic response due to the buffering ca- pacity of body fluids, and a more chronic compensation (1–2 days) due to alterations in renal function. The degree of compensation is well known and can be expressed in terms of the degree of the primary acid–base disturbance. Table 8–2, page 164, lists the major categories of primary acid–base disorders, the primary abnormality, the secondary compensatory re- sponse, and the expected degree of compensation in terms of the magnitude of the pri- mary abnormality. Most acid–base disorders result from a single primary disturbance with the normal physiologic compensatory response and are called simple acid–base disorders. In cer- tain cases, however, particularly in seriously ill patients, two or more different primary disorders may occur simultaneously, resulting in a mixed acid–base disorder. To determine a mixed acid–base disorder from a blood gas value, follow the six steps in the Interpretation of Blood Gases (in the following section). Alterations in either [HCO −] or pCO that differ from expected compensation levels indicate a second 3 2 process. Two of the examples given in the following section illustrate the strategies em- ployed in identifying a mixed acid–base disorder. INTERPRETATION OF BLOOD GASES Use a uniform, stepwise approach to the interpretation of blood gases.

During the choice phase cheap 4 mg atacand fast delivery, the actual decision to follow a certain course of action is made atacand 8mg mastercard. If a single option results from the design phase, the choice phase is a simple acceptance or rejection of the option. If multiple courses of actions are identified in the design phase, then the decision makers are challenged in choosing from multiple conflicting objectives. Some decision rules for multivariable problems have applied strategies like holistic evaluation methods, heuristic elimination, and holistic judgment. During the review phase, the outcomes of the decision making process are reviewed for validity and applicability for the case in hand. Any deviation and changes to these outcomes could very well become an expert knowledge that can be fed back into the knowledgebase to help future decision making cases. Several studies were performed to identify the characteristics and functions of a medical decision support system. Turban and Aronson (2000) and Beatty (1999) have performed extensive research in this area of medical decision support system. Turban and Aronson (2000) summarizes the characteristics into few categories as listed below. Support decision makers in semi structured and unstructured situations by bring- ing medical expert judgment and computer knowledgebase together. Support decision making when the problem area consists of various inter-depen- dent and/or sequential paths. This allows new learning, adjustments to current knowledge and knowledge pattern recognition. Copying or distributing in print or electronic forms without written permission of Idea Group Inc. Even a great decision support system can be useless if the users are challenged by its interface. Should provide both automated and interactive decision support depending on the nature of the problem/opportunity.
