Abstrakt: Clinically validate (using Fehring's model) characteristics of the nursing diagnosis (ND) of decreased cardiac output (DCO) in 29 patients with decompensated heart failure. Cross-sectional study conducted in a Brazilian university hospital. According to the reliability rate (R) between the experts, the major characteristics (R ≥ 0.80) were fatigue, dyspnea, edema, orthopnea, paroxysmal nocturnal dyspnea, and elevated central venous pressure, and the secondary characteristics were weight gain, hepatomegaly, jugular vein distension, palpitations, crackles, oliguria, coughing, clammy skin, and skin color changes. Characteristics with R > 0.50 and ≤1 were valid in the ND of DCO. Implications for the nursing practice: Clinical validation studies are necessary to determine the adequacy of this diagnosis and its determining characteristics with Taxonomy II. Validar clinicamente, segundo o modelo proposto por Fehring, as características definidoras do diagnostico de enfermagem (DE) débito cardíaco diminuído (DCD) em 29 pacientes com insuficiência cardíaca congestiva descompensada. Estudo transversal conduzido em um hospital universitário no sul do Brazil. De acordo com a taxa de fidedignidade de Fehring (R) obtidas entre as peritas, as características definidoras consideradas maiores (R ≥ 0.80) foram fadiga, dispnéia, edema, ortopnéia, dispnéia paroxística noturna e pressão venosa central aumentada; e características secundárias foram ganho de peso, hepatomegalia, distensão da veia jugular, palpitações, crepitações, oliguria, tosse, pele fria e pegajosa e mudanças na cor da pele. Características com R > 0.50 e ≤1 foram validadas para o diagnóstico débito cardíaco diminuído (DCD). Estudos de validação clínica são necessários para evidenciar a adequação deste diagnóstico e suas características definidoras a Taxonomia II. [ABSTRACT FROM AUTHOR]
