Validation of the concept Risk for Decreased Cardiac Output

Abstract

Objectives: to validate the concept "risk for decreased cardiac output". Method: Six of the eight steps suggested in the technique developed by Walker & Avant were adopted to analyze the concept of the phenomenon under study and the proposal made by Hoskins was used for content validation, taking into account agreement achieved among five experts. Results: the concept "decreased cardiac output" was found in the nursing and medical fields and refers to the heart's pumping capacity while the concept "risk" is found in a large number of disciplines. In regard to the defining attributes, "impaired pumping capacity" was the main attribute of decreased cardiac output and "probability" was the main attribute of risk. The uses and defining attributes of the concepts "decreased cardiac output" and "risk" were analyzed as well as their antecedent and consequent events in order to establish the definition of "risk for decreased cardiac output", which was validated by 100% of the experts. Conclusion: The obtained data indicate that the risk for decreased cardiac output phenomenon can be a nursing diagnosis and refining it can contribute to the advancement of nursing classifications in this context. Validación del concepto riesgo de débito cardiaco disminuidoObjetivo: Validar el concepto riesgo del débito cardíaco disminuido. Método: Fue adoptada la técnica de Walker & Avant para analizar la definición del fenómeno enfocado, utilizando seis de las ocho etapas sugeridas y la propuesta de Hoskins para validar el contenido, considerándose la conformidad entre cinco expertos. Resultados: el concepto de debito cardíaco disminuido se encuentra en las áreas enfermería y médica y su atención se centra en la capacidad de bombeo del corazón. Sin embargo, el concepto de riesgo es presente en un gran número de áreas. Las características definitorias de la disminución del gasto cardíaco mostraron como principal atributo deficiencia de la bomba cardiaca y, para el riesgo, el atributo de probabilidad.Analizados los usos y características definidoras de los conceptos "débito cardíaco disminuido" y "riesgo" con los hechos anteriores y subsiguientes, fue posible elaborar la definición de "riesgo de débito cardíaco disminuido", la cual fue validada por 100% de los expertos. Conclusión:Los resultados encontrados permitieron concluir que el fenómeno de riesgo de débito cardíaco disminuido puede constituir un diagnóstico de enfermería y su refinamiento puede contribuir al avance de las clasificaciones de enfermería. This study can contribute to the advancement in the subject since this diagnosis is seldom explored in studies conducted in the nursing field and NANDA is considering it for potential inclusion in its classification. ObjectivesTo validate the concept of decreased cardiac output. MethodStudy developed in two phases: analysis and validation of the concept decreased cardiac output. Concept analysisThis stage was developed between 2006 and 2012 using six of the eight steps suggested in the technique described by Walker & Avant Content v...

Analysis of the concept of powerlessness in individuals with stroke

“…(10) It is also seen that in this taxonomic classification system all diagnostic categories are derived from concepts and present theoretical models or formulations (11) to give meaning to the observations of physiological, psychic, social, religious and spiritual phenomena, going through continuous analyzes according to studies found in the literature. (12)(13)(14)(15)(16)(17)(18)(19) As already mentioned, the conceptual definition of powerlessness (00125) standardized by NANDA-I is "lived experience of lack of control over a situation, including a perception that one's actions do not significantly affect a result."

Nursing diagnosis in adult patients with cardiovascular conditions: an integrative literature review

“…Esse DE está relacionado, principalmente, à diminuição da fração de ejeção do ventrículo esquerdo, resultando em sinais e sintomas como a dispneia, graças à incapacidade do coração em manter um débito cardíaco suficiente para satisfazer as necessidades teciduais de oxigênio, e edema nos membros inferiores, associado à presença do débito cardíaco, evidenciado pela infiltração no espaço intersticial e redução do fluxo sanguíneo periférico, associado à intolerância à atividade. (27,28) O risco de intolerância à atividade física é o DE destacado nas pessoas que correm o risco de não realizar atividade física suficiente ou completar uma rotina de atividade física regular. (24) É necessário que a assistência de enfermagem permita avaliar quais os possíveis fatores fisiológicos e motivacionais resultantes dessa intolerância, seja por estado de saúde comprometido ou ausência do autocuidado, tendo em vista as diversas doenças cardiovasculares que impossibilitam a realização de exercícios de alto impacto, o que permite a atuação de uma equipe multiprofissional para prestação da assistência qualificada.…”

Risk factors for decreased cardiac output after coronary artery bypass grafting: a prospective cohort study

“…Considering this perspective, a concept analysis of risk for decreased cardiac output (00240) was previously developed, consisting of its definition and validation by experts and the identification of its risk conditions in the literature. 10 This proposal was submitted to NANDA-I for possible recognition as a nursing diagnosis, approved and included in the 2015-2017 classification with the definition 'Vulnerable to inadequate blood pumped by the heart to meet metabolic demands of the body, which may compromise health' and six risk factors (alteration in heart rate, alteration in heart rhythm, altered afterload, altered contractility, altered preload and altered stroke volume; NANDA-I). 8 However, no previous study has investigated the predictive risk factors of the nursing diagnosis of risk for decreased cardiac output after CABG.…”
