Analysing arterial blood gas results using the RoMe technique

Marlon Bernardo Lecturer in nursing education, Faculty of Nursing, Midwifery and Palliative Care, King’s College London, London, England

Why you should read this article:
  • To enhance your knowledge of basic arterial blood gas analysis

  • To gain an understanding of various acid-base imbalances and the compensatory mechanisms associated with these

  • To learn how to apply the RoMe (‘Respiratory opposite, Metabolic equal’) technique when analysing arterial blood gas results

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.
