"Respiratory analysis demonstrated 7 obstructive apneas, 0 mixed apneas, and 318 central apneas. A total of 325 apneas and an apnea index of 45.2 events/hour was recorded. There were 101 hypopneas, with a hypopnea index of 14.0 events/hour. The APNEA HYPOPNEA INDEX (AHI) was 59.2 events/hour. The patient had a RESPIRATORY DISTURBANCE INDEX (RDI) of 63.3 events/hour.
Central Apneas associated with Periodic Breathing noted. Removing these Central Apneas from the APNEA/HYPOPNEA INDEX (AHI) decreased the overall APNEA/HYPOPNEA INDEX (AHI) to 17.5 events/hour.
The lowest desaturation was to 72%. Mean oxygen saturation was normal while awake. The mean saturation while asleep was 93%. Mean oxygen saturation was decreased while in NREM Sleep (mean SaO2 of 91%) and normal while in REM Sleep (mean SaO2 of 98%). The patient spent 73.5% of the total sleep time having a SaO2 > 90% and 10% of the total sleep time having a SaO2 between 80-89%.
This was an abnormal study.
Severe Obstructive Sleep Apnea was recorded (AHI equal to 17.5 events/hour).
Oxygenation was abnormal, with hypoxia recorded while asleep.
Ventilation was normal.
Moderate, intermittent snoring was noted.
Of note, there was a significant amount of periodic breathing recorded during this study, several of these events last for several minutes.
Clinical Correlation required.
Thank you for reading my novel ;-) I would also appreciate any advice as to what I should be looking for or ask for in a mask / machine. He also has Aspergers, it might be a challenge sensory wise to find a mask he feels comfortable with.
