RDI was high
Rera is factored into a number called the rdi (respiratory disturbance index).
Ahi is the apnea-hypopnea index, meaning you stopped breathing or had a 50% reduction in airflow with desaturation(drop in oxygen
) an average 1 time per hour. When rera is added, you get a rdi score and this was elevated. Rera's are events where there is resistance to airflow but not enough to call apnea or hypopnea.
