Abstract

Arterial blood gas analysis is a fundamental tool for assessing the acid-base and respiratory status of critically ill patients. Its incorrect interpretation can compromise therapeutic decisions in intensive care units. Objective: The aim of the study was to determine the causes of error in the interpretation of blood gas analysis by intensive care staff. Method: A qualitative literature review was conducted of publications indexed between 2018 and 2022 in databases such as PubMed, Scielo, Lilacs, and Dialnet. Results: The results showed that the highest proportion of errors occurred in the pre-analytical phase (46–75%), while the analytical phase presented between 19–22% of errors, mainly associated with inadequate sampling, incorrect transport, the presence of air bubbles, and deficiencies in clinical interpretation. Conclusion: It was concluded that continuous training and standardization of procedures were essential to reduce errors and optimize decision-making in critically ill patients.
