A patient presents with respiratory distress and shows pH = 7.2, PCO2 = 50 mmHg, PO2 = 85 mmHg and HCO3 = 20 mEq/L. The cause is
Metabolic acidosis
Metabolic alkalosis
Respiratory acidosis with compensatory Metabolic alkalosis
Respiratory acidosis with decompensatory Metabolic acidosis
(D) Respiratory acidosis with decompensatory Metabolic acidosis PREDICTION OF COMPENSATORY RESPONSES ON SIMPLE ACID-BASE DISTURBANCESDisorderPrediction of Compensation* Metabolic acidosisPaco2 = (1.5 x HCO3-) + 8OrPaco2 will | 1.25 mmHg per mmol/L |in orPaco2 = + 15* Metabolic alkalosisPaco2 will | 0.75 mmHg per mmol/L | in Paco2 will | 6 mmHg per mmol/L | in Paco2 = + 15* Respiratory alkalosis * Acute will | 2 mmol/L per 10 mmHg |, in Paco2* Chronic will|4 mmol/L per 10 mmHg | in Paco2* Respiratory acidosis * Acute will | 1 mmol/L per 10 mmHg | in Paco2* Chronic will | 4 mmol/L per 10 mmHg | in Paco2
