To analyze the relevance of clinical indicators and the clarity and precision of conceptual and operational definitions of the diagnosis Impaired gas exchange.
Content analysis, by 39 nurse judges, divided into the phases of conceptual definition of the phenomenon of interest, construction of the structure of the phenomenon of interest and analysis of the judges on the built structure.
From the 22 indicators, 21 were considered relevant Impaired gas exchange. The indicators that obtained absolute relevance were Cyanosis, Hypercapnia, Hypoxemia and Tachycardia. The indicator Headache upon waking did not show any statistically significant relevance for the diagnosis. All conceptual and operational definitions were clear and precise.
The indicators listed for Impaired gas exchange were relevant to the phenomenon, except Headache upon waking because it does not correspond to a safe manifestation to identify the diagnosis, according to the analysis of the judges. Each conceptual and operational definition was adequate for its indicator.
分析临床指标与诊断“气体交换受损”的概念和操作定义的清晰度和精确性之间的相关性。
内容分析法，由 39 名护士评判员分为感兴趣现象的概念定义阶段、感兴趣现象的结构构建阶段以及评判员对构建结构的分析阶段。
在 22 个指标中，有 21 个被认为与“气体交换受损”相关。绝对相关的指标有发绀、高碳酸血症、低氧血症和心动过速。醒来时头痛这一指标与诊断无显著相关性。所有概念和操作定义都清晰准确。
除了醒来时头痛，因为它与识别诊断的安全表现不符，所以列出的用于诊断“气体交换受损”的指标与该现象相关。每个概念和操作定义都与各自的指标相适应。
