Purpose To analyze the accuracy of the defining characteristics of impaired gas exchange ( IGE ). Methods Cross‐sectional study carried out in 93 cardiac postoperative adult patients. The 19 NANDA ‐ I defining characteristics related to IGE were evaluated. Findings Ten defining characteristics were found in the sample. The best accuracy values, including specificity, diagnostic odds ratio, and likelihood ratios, inter alia, were found to decreased carbon dioxide, abnormal arterial blood gases, abnormal arterial pH , and abnormal breathing. Conclusion Some clinical indicators predict the presence/absence of IGE more accurately than others. Implications for Nursing Practice Knowledge of the accuracy of defining characteristics allows an early identification of particular nursing diagnoses, which can prevent complications.
