In 452 minutes of sleep 304 episodes of apnea were scored, 288 were central (meaning there was no effort), 7 were obstructive. Another 158 episodes of obstructive hypopnea were identified. Hypopnea is when there is a 30-90% reduction in airflow. The overall AHI (apnea-hypopnea index) was 52. AHI is used to determine the severity of sleep apnea 5-15 is mild, 15-30 is moderate, and above 30 is severe.
Daylon's oxygen saturation dropped significantly as low as 55% at one point. His oxygen level was below 90% for 20% of the study.
Obstructive Sleep Apnea, Central Sleep Apnea, and Hypoxemia
Have airway reassessed by ENT, and CPAP would also be a possibility.
We are not able to see ENT until December 14th, but saw Dr. T today. He does not feel that ENT is going to find anything that they can fix, so he wants to get Daylon on a CPAP if at all possible. We tried a little bit today, but he wasn't having it, so we will do an overnight CPAP titration study on January 4th.
