Objectives: The process of organ donation is the starting point of this study, whose objec­tive was to describe and analyze the resonances of care that the living renal donor family establishes with the recipient family member in the donation process. Material and methods: It was developed as an exploratory descriptive qualitative research; the sample consisted of six living renal donor relatives residing in Lima-Peru, determined by criterion of theoretical saturation. The data collection was done through in-depth inter­views conducted in the homes of the participants in 2017. The data was organized, classified, categorized according to Minayo criteria and the theoretical basis of Boff. Orlandi’s oral discourse analysis was used to construct the empirical categories that emerged from the texts. Results: From the analysis of discourse, the Care-Life construct emerges and the resonance of love simultaneously complements the resonances of Compassion, Tenderness, Caress, Hope, categories that have as theoretical, epistemic and philosophical support the resonances of care human. Conclusions: Among the conclusions of the study, the resonance of love is the main category that emerges from the kidney donor relative in the Care-life construct, it is cemented in the care for the survival, conservation and well-being of the recipient family of organs, where the resonance of love is revealed as the great force that transforms life, unites and solidifies in conjunction with compassion, caress, tenderness, hope, resonances that humanize the care of the family, sensitize the act of organ donation.
