Introduction

Cardiac output/pulmonary blood flow measurement is an important way to assess patients during the perioperative period, as well as patients who are critically ill. Current methods of assessing cardiac output have limitations. One indicator of cardiac output may be the expired carbon dioxide (CO₂) partial pressure response to intravenous sodium bicarbonate (IVSB), which is rapidly converted to CO₂.
