[Analytics of ambiguity: methodological strategy to the phenomenological research in health].

The strategy presented in this paper, called Analytics of ambiguity, is connected to the necessity of understanding findings in researches based on Merleau-Ponty's phenomenology. It was developed through a study of descriptions of life experiences from ten family members, members of a Mutual Help Group for caregivers of Alzheimer's patients, conducted at a university in Florianopolis, Santa Catarina, Brazil. Such descriptions were shown through interviews based on intercorporeal experience, during the writing of a Doctoral Dissertation in Nursing. The application of the Analytics of ambiguity to this study is consistent with other similar studies and opens up possibilities for the understanding of findings in phenomenological researches, specifically those based on the experiential ontology of Merleau-Ponty, for it enables us to recognize consciousness as something non-perceptible and perception as an always ambiguous process.
