O2D2 mount location

[NewMoon]

Just bought the unit, wondering where folks mount/set them while in flight? 

Between the seats? On the back seat? 

Ideas and photos would be great.

I did a write-up on this and posted some pics not too long ago, available here:

 

You may want to avoid zip tying the oxygen line to any wires, and plan to protect it from damage.

Good luck, still love my setup.

Are you using a built in bottle or a removable bottle in the back seat?

I use a removable bottle in the back seat so I put my o2d2 on the ceiling attached to the cabin light screw strapped in with a velcro strap.  Its a nice place for it because its always at hand ready to go and it keeps the tubes nicely untangled.  The tubes go up from the back seat bottle, then down to our heads in the front.  No fuss.

I have built in O2.

I put mine on the glare shield with heavy duty Velcro.  I like having it in view for warning lights.

I happened to be doing interior shortly after I purchased an O2D2, and had a small pocket sewn in the back of the copilot seat.  But you could also make a pocket that straps around the head rest and hangs high just under the copilot headrest as well.  My O2 connections were right above that in the headliner, so this was a good place.  However, it all depends on where your oxygen connection is to help minimize tubes going everywhere.

I do like the fact that it's out of the way, but I agree with @Pinecone that it is nice to have it somewhere within eye glance...although not completely necessary since it's a pulse demand delivery.  If either oxygen stopped or unit stopped, the pulses would stop.  BTW, ANC on my headset really makes the alarm quiet with the engine running unless it was right by your head.

But if my oxygen connector was on the side wall, I'd likely mount it right here like one of my buddies did.  His tubing comes out a hole in the sidewall along the arm rest so that it keeps the regulator tucked and out of the way.

These adhesive cable tie mounts make it easy to keep the oxygen line separated and tamed:

1) How do you know the pulses stopped?  Realizing that you may be distracted, and if it happens for a bit, you may be hypoxic and not realizing. There is a visible warning on the unit.

2)  You can wire the unit to your audio panel so you can hear the alarm

My 252 O2 outlet is on the arm rest.  So the tubing goes forward to the panel, then up and along the edge of the glare shield to the unit.

[Marc_B]

So if unit ran out of batteries, tubing became disconnected/kinked, or oxygen ran out, the nasal pulse doesn't deliver oxygen. The pulse unit only controls the length of time of the pulse and the frequency that it occurs.  At least for me, it's pretty easy to tell if that stops and up until then I should have decent saturation.  Pulses are noticeable.  Much easier to notice loss of pulse than loss of unperceived constant flow.

 

[Pinecone]

But will you notice if there are other things grabbing your attention?

I agree, that under normal cruise, I can tell if I am getting pulses of O2.  But I will not only rely on that.

[Marc_B]

Stock constant flow has no alarms, no lights, and the flow isn't nearly as perceptible as an on-off pulse.  I have my oxygen connection in the headliner which makes it difficult to mount the unit in a "best location for the utmost visibility and safety."  But I'm VERY happy with my location, visibility, and safety plan.  Glad you found a place you like as well!  OP asked for mount options.  There are more than one potential locations that work, tame the tubes, and are safe. 

In general, there are so many things I am scanning and looking at on a routine basis while flying (including the O2D2).  You don't need to smack me in the head with them in order for me to recognize them.  And studies have shown that in high stress, multi-tasking situations you can completely ignore stimuli that are smacking you in the face.  I'm comfortable with my safety margin, have 2 pulse ox's in the aircraft / use them every 15-20 minutes when using oxygen, change the batteries in the O2D2 unit and pulse ox's at annual regardless of capacity, and typically don't let my oxygen get down to less than 1/3-1/2 tank before topping off.

@Pinecone I agreed with you from the beginning in my first post.

Back to the original request.  Post up any photos of your mount locations so the OP can find what works for their situation.

Late to the party, but wanted to get some pics.  I tried the way Z W used on the pedestal, but I kept kicking the unit when trying to exit the aircraft (user error, I've no doubt, but I couldn't seem to fix myself).  I went a little crazy and 3D printed a frame to hold it to the overhead using the panel screws already there.  I thought about the velcro strap thing, but kept seeing it swinging and hitting my head, so I overdid it.  My first attempt was the purple one, which worked really well until a trip to Alabama in the summer when I learned how hot it gets inside a covered plane.  The second attempt (the white one) gave a lot more bottom support.  The unit sits right next to my head while I'm flying, so alerts are easy to hear, even thru an ANR headset.  I put the inline regulator up there too so its easy to check as I've had the tube come loose there before and start bleeding O2 (gets real cold when it leaks and its an easy check there).  If I were to do it again, I'd consider putting that up on the armrest.  I wrapped the O2 line from the onboard tank for some extra protection and just run it up behind my seat (still looking at ways to run it better) and the masks are just in the back pocket, easy to grab when needed.  All the hoses come in over your shoulder.

@Grumpy I experimented around with adhesive/velcro in the headliner and came to the same conclusion.  Easy to get too hot even stopping for lunch and adhesive wouldn't hold the weight of the unit.  Considered mounting a velcro strap using washers and screws through the velcro to keep it up instead of adhesive.  But as you found it's hard to get that tight.  My creativity stopped there for the overhead and I didn't even think about a printed part.

I have a pouch that hangs from the head rest between the two front seats. That way everybody hears the deedle deedle if something changes.

I have but a single O2D2.  I didn't understand your comment about switching every 15-20 minutes?

I have a finger pulse oximeter hanging on my prop knob that I check my oxygen saturation every 15-20 min while up in the levels.  It gives me something to do when I'm bored and keeps me safe.

Thanks.  I misread your post at first, but now I get it.

[Pinecone]

I got a ring style pulse ox.  You can leave it on, and it alarms (vibrates) at a user set point.  Also logs to your phone.
