Analysing arterial blood gas results using the RoMe technique

Research output: Contribution to journalArticlepeer-review


Arterial blood gas (ABG) analysis is a fundamental skill in healthcare practice, particularly when caring for acutely unwell or deteriorating patients. It can be useful in the assessment of patients' acid-base balance and gas exchange, thereby informing appropriate care and management. However, many nurses find interpreting ABG results challenging. This article outlines a simplified approach to ABG analysis using three main values - pH, partial pressure of carbon dioxide and bicarbonate - and applying the RoMe ('Respiratory opposite, Metabolic equal') technique. It also provides brief descriptions of selected acid-base imbalances and explains how to identify whether these are uncompensated, partially compensated or fully compensated.
