The authors describe two cases of metabolic acidosis, caused by diabetic ketoacidosis in the first case and by dehydration following gastroenteritis in the second one. Both patients were followed with noninvasive end-tidal CO2 (ETCO2) monitoring. A correlation between EtCO2 and PCO2 and HCO3- has been established in the literature. Noninvasive ETCO2 is used in only 5-6% of metabolic emergencies. In contrast, users described its use as easy and convenient.
