NAMI whammy

I am up for board consideration as an SNA. During my flight app they took xrays of my sinuses (the flight doctor said they weren't necessary for the application) and i had a slight buildup in one of my sinuses. Is this going to come back to haunt me when I get down to Pensacola if it hasn't cleared up by then?

Basically what can they disqualify you for concerning sinuses?

I'm no doctor either, so I am just going to tell you what I know. People who can't pop their ears, and people who can't make it through the compression chamber without feeling like their head is going to explode are the cases I am referring to. If those things occur they proceed medically from there. Some NPQ, some get sinus surgery, some get a second try and pass because they didn't realize they had a slight cold. It is really a case by case basis from what I've seen. Review the standards for a naval flight physical and waiver requirements. They might answer some specific questions.

I believe the correct answer to that would have been;

This sparked my interest. I have always heard about smoking having some temp. effect on vision. What is the story with chewing tobacco? Never been too clear on what physical effects dip has on someones body (besides the obvious oral problems). Thanks Doc.


BTW, I forgot to mention that exercise prior to flight can also interfere with vision...lactic acid binds with hemoglobin and will prevent O2 uptake, much in the same manner as smoking (via carbon monoxide). Sucking on the mask, by itself, will not change this chemical bond.

Being O2 deprived alters vision this way.....the eye muscles become weak and uncoordinated...pupils constrict....retinal vessles become cyanotic.....accommodation goes down the crapper, causing your vision to decrease. So, anything that alters the RBCs ability to carry O2 is bad. Hence the reference to alcohol and smoking. As for smokeless tobacco...*I think* that nicotine can alter the way hemoglobin carrys O2. Still researching......

And I overread the first question on this page. NOMI is the Naval Operational Medicine Institue...where as NAMI is the Naval AEROSPACE Medical Institute.

Look forward to hearing more. I've been doing some looking around and all I can find is smoking info or someone trying to sell me some stop-smoking crap - and a few dip-is-bad posters.

Not a whole lot of solid info on what dip does to the rest of your body.

NOMI, NAMI

Not so fast....

NAMI does not equal NOMI although one grew out of the other and now NAMI is a "detachment" under NOMI. See their "combined" history here.

NOMI vs NAMI (and NAOMI)

You forgot NAOMI. Crap, I hated that name.

Nope. It's OBE (so I didn't mention it) since only lasted 4 years as they state in the history:

On 1 April 1981, the Naval Aerospace Medical Institute became an Echelon Three Command, reporting directly to the Bureau of Medicine and Surgery (BUMED). The Commanding Officer of the Institute continues to report to the Commander, Naval Education and Training Command for area coordination.

On 7 December 1992, the Secretary of the Navy authorized the official name of the Institute to be changed to the Naval Aerospace and Operational Medical Institute.


On 17 December 1996, BUMED authorized the Naval Aerospace and Operational Medical Institute (NAOMI) to change its name to the Naval Operational Medicine Institute (NOMI).

On 1 October 1999, the Fleet Hospital Operations Training Command (FHOTC), the Surface Warfare Medicine Institute (SWMI), and the Naval Undersea Medical Institute (NUMI) became a component and detachments of NOMI respectively.

In July 2000, the Naval Aerospace Medical Institute (NAMI) was established as a detachment under NOMI to meet new and evolving requirements for aerospace medical specialty training, aviation consultative services, and for aviation physical screening and standardization.

See the total history for continued influence and growth of NOMI to encompass all warfare specialities including Special Operations related medicine.

All the above is correct. Also I think it is more of a blood flow problem. Nicotine causes dialation of vessles and increase of heart rate which together gives less time for the O2 to bind to the hemoglobin. A normal person will bind three O2 to each hemoglobin but with nicotine it decreases the "chance" of binding.

The consensus amongst my cohorts from Quantico, Pensacola and DC is that chewing tobacco does not have an effect on O2 transport.

In general, nicotine does this: causes a quick release of adrenaline which>> increase heartbeat, BP along with rapid and shallow breathing >>> tells your body to dump glucose stores into the blood. Nicotine may also
block insulin release (insulin tells your cells to take up extra glucose) which could lead to hyperglycemia which, in turn, could lead to decreased hunger sensations. Nicotine may also increase basal metabolic rate slightly, burning more calories. (that is why most smokers/chewers are thin)

However, this is not a healthy excuse using this as a means of weight loss.
In the long term, nicotine will likely increase the level of LDLs which will damage your arteries....hence the main reason why tobacco users are more likely to have a stroke or MI.

That is great info Doc, I can see you put some effort into it and I appreciate that.

Do you make it a habit to confirm the medical knowledges of physicians?
