The differential diagnosis of acid-base disorders is extensive (table 4-1) but can be easily organized into 4 distinct subsets by first determining whether the primary disorder is a (1) metabolic acidosis, (2) metabolic alkalosis, (3) respiratory acidosis, or (4) respiratory alkalosis the key pivotal feature that allows the clinician to. Case study: bob is a 64-year-old male admitted to the emergency room for asthma his laboratory results are as follows: ph 731, pco2 higher than normal, and total hco3– also higher than normal classify his acid-base balance as acidosis or alkalosis, and as metabolic or respiratory is there evidence of compensation.

We present here an approach to teaching the biochemical basis of acid-base balance which we believe allows students to have an enjoyable introduction to a difficult subject and which we have found prepares them satisfactorily for a variety of subsequent applications in their medical studies the clinical situation. Acid-base diagnosis ph: ph is greater than 744 so an alkalaemia is present the cause is an alkalosis pattern: pco2 & bicarbonate are both low suggesting either a metabolic acidosis or a respiratory alkalosis as we already know an alkalosis is present then the primary disorder is a respiratory alkalosis clues: the.
