Chronic nasal obstruction cause throat collapse? poll please

[williamco]

I am wondering about this possibility as I noticed so many people over here talking about nasal obstruction:

Chronic nasal obstruction will cause negative pressure inside your throat because as you try to inhale against the obstruction you have suck more , create more negative inside your throat, that might cause your throat to buckle in over time, slack off, and while sleeping with low muscle tone your extra slacking tissue will relax and buckle in closing your throat.

I am wondering how many of us had chronic nasal obstruction prior to being diagnosed with sleep apnea?
to assess the importance of this issue as a cause of apnea, specially that while you are being treated by CPAP, continuing to have nasal obstruction might progress your apnea condition and causes increase in pressure requirement as a result

Actually, reasonable as it might sound, I would check out your theory with an ENT MD before assuming it's valid and doing a poll on it.

It's not a theory he invented as it turns out.

Starling Resistor modeling shows that increased nasal resistance facilitates a suction-type (transluminal) collapse or downward sagging in the pharyngeal area. Not everyone is particularly susceptible to that airway-collapse dynamic, but I sure am! If I progressively and very slowly pinch my nostrils closed, I can feel my upper airway just as progressively closing to a point of pharyngeal blockage. Those are the same dynamics that occur when a paper straw collapses while drinking an overly-thick milk shake. Those same high nasal-resistance dynamics---in much less severe proportions than my experiment---are probably sufficient for RERAs and/or microarousals in certain patients. And those same suction-type dynamics are what account for the majority of discussion in these links I presented earlier. Additional Starling Resistor references:

That is on inhale.

Apparently it has the reverse effect on exhale - http://www.proventtherapy.com/about-pro ... erapy.aspx

Yup... those supposedly add negligible resistance during inhale, but significant resistance during exhale. The back-pressure created during that latter exhale stage supposedly proactively biases the upper airway with static pressure right at the end of exhale when obstructive apneas tend to set in.

We've had some interesting discussion about those as well:

But those are altogether different mechanics for an altogether different respiratory phase than Williamco is polling for...

Yes, I too had this problem so i discussed it with my allergist, he recommended that I sleep on 3 pillows. That was miserably uncomfortable for me, so I bought a 7" Bed Wedge, I am now sleeping better.
He said that when we lie down blood rushes to the sinuses which causes them to plug up. I have found this to be true. At first I had purchased a 10" wedge but it was too high for me. I returned it and exchanged it, it is so much better.
