Pectus Carinatum/Pigeon Chest can it affect your breathing, leading to irregular breathing causing bad sleep 'patterns'? Any suggestions?

[Adlon57]

I've had pectus carinatum due to meningitis when aged 10 years old, I've always bad sleep, the deformed chest, lower on my right hand side, could they be linked? I am aged 68,[so too late to get it surgically altered] and have epilepsy and fractured/broken every rib in my body, especially in 2017, I fell off my exercise bike, and shattered my sternum, at least 5 ribs! Could taking oxygen at night help my breathing thus a more 'natural' sleep?
