Polisomnografía - Results

Nombres alternativos

Estudios del sueño; Polisomnograma; Estudios de los movimientos oculares rápidos; Polisomnografía de parte de la noche; PSG

Valores normales:

Una polisomnografía registra:

Con qué frecuencia usted deja de respirar durante al menos 10 segundos (denominado apnea).
Con qué frecuencia su respiración se bloquea parcialmente durante 10 segundos (llamado hipopnea).

Los resultados casi siempre se informan usando el índice de apnea e hipoapnea (IAH). Un IAH de menos de 5 se considera normal.

Significado de los resultados anormales:

Los resultados del índice de apnea e hipopnea (IAH) se usan para diagnosticar la apnea obstructiva del sueño.

5 - 15 es apnea del sueño leve
15 - 30 es apnea del sueño moderada
Más de 30 es apnea del sueño grave

El especialista del sueño también debe examinar otros hallazgos a partir de la polisomnografía, la historia clínica y el examen físico para hacer el diagnóstico y decidir sobre el tratamiento. Una polisomnografía también puede ayudar a diagnosticar la narcolepsia.
