Resumo


A Apneia Obstrutiva do Sono (AOS) é uma síndrome caracterizada por episódios de obstrução das vias aéreas, que provoca eventos de dessaturação de oxigênio. Estes eventos podem ser identificados pela análise da oximetria e são utilizados como um dos parâmetros para diagnosticar a AOS. Porém, sua definição é pouco precisa em manuais e na maior parte da literatura. Desta forma, este trabalho busca avaliar se diferentes metodologias para o cálculo de eventos de dessaturação causam impacto no íIndice de Dessaturação de Oxigênio (IDO) e no diagnóstico de AOS. Os resultados indicaram que os valores de IDO são significativamente diferentes entre si (p <0,001) e que as metodologias apresentaram performance variável para diagnóstico de AOS.
