Clinical Indicators of Impaired Gas Exchange in Cardiac Postoperative Patients

Abstract

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.

Propósito

Analizar a acurácia das características definidoras de Troca de Gases Prejudicada (TGP).

Méthodo

Estudo transversal desenvolvido com 93 pacientes adultos no pós-operatório cardíaco. Dezenove características definidoras da NANDA-I associadas a TGP foram avaliadas.

Resultados

Dez características definidoras foram encontradas na amostra. Os melhores valores de acurácia, incluindo especificidade, odds ratio diagnóstica e razões de verossimilhança, entre outras, foram encontrados para as características definidoras dióxido de carbono diminuído, gases sanguíneos arteriais anormais, pH arterial anormal e respiração anormal.

Conclusão

Alguns indicadores clínicos predizem a presença/ausência de TGP mais precisamente que outros.

Implicações para a prática de enfermagem

O conhecimento acerca da acurácia das características definidoras contribui para uma identificação precoce de diagnósticos de enfermagem específicos, o que pode prevenir complicações.
