I am having an idea that CPAP might not be able to fully correct obstruction that is caused by tongue, for these reasons:
1-soft palate and throat are thin easy to push tissues by high pressure, the base of the tongue is the thickest component in the throat
2- the aerodynamic of pressured air going down in the throat, might push soft palate away (backward in mouth air delivery, or forward in nasal air delivery) and push throat backward in either path of air delivery , but tongue is the only component that relaxes downward during sleep so it needs to be pushed upward, no pressured air going down the throat can push the tongue upward in opposite direction of the air pathway, this is against physics, however CPAP can only work in this case by creating more space in the throat soft tissue by the pressured air but no direct impact on the tongue
However only mouth air delivery can push the back of the throat a bit more, because air is going in straight direction at back of the throat, opening more space for the relaxed tongue.
this aerodynamic can't happen with nasal air delivery as the air going down not hitting the back of the throat in a straight head on direction, yes transmitting pressure all around but in not as much as direct hit
Further more air going down (nasal delivery) might push the tongue down even further, while air going backward (mouth delivery) will not be in line of the tongue relaxation path, and will not push it further down, as air is bouncing off the back of the throat into trachea, might even push tongue forward.
the bottom line, I need to check if aerodynamic of nasal air delivery versus mouth air delivery inside the throat, has any impact of those people who are still tired. knowing that it might be many factors involved, so the poll might help to shed light by showing the percentage of usage in this group.
Thanks for participation
