Abstract

Objective: to evaluate the usefulness of capnography for the detection of metabolic changes in spontaneous breathing patients, in the emergency and intensive care settings. Methods: in-depth and structured bibliographical search in the databases EBSCOhost, Virtual Health Library, PubMed, Cochrane Library, among others, identifying studies that assessed the relationship between capnography values and the variables involved in blood acid-base balance. Results: 19 studies were found, two were reviews and 17 were observational studies. In nine studies, capnography values were correlated with carbon dioxide (CO2), eight with bicarbonate (HCO3), three with lactate, and four with blood pH. Conclusions: most studies have found a good correlation between capnography values and blood biomarkers, suggesting the usefulness of this parameter to detect patients at risk of severe metabolic change, in a fast, economical and accurate way.

RLAE’s authorship concept is based on the substantial contribution by each of the individuals listed as authors, mainly in terms of conceiving and planning the research project, collecting or analyzing and interpreting data, writing and critical review. Indication of authors’ names under the article title is limited to six. If more, authors are listed on the online submission form under Acknowledgements. The possibility of including more than six authors will only be examined on multicenter studies, considering the explanations presented by the authors.
Including names of authors whose contribution does not fit into the above criteria cannot be justified. Those names can be included in the Acknowledgements section.
