- In this video, George goes over the basics and components of a portable liquid oxygen portable (stroller) and the liquid oxygen reservoir (stationary) tank
Nice! Thanks
What is the maximum continuous flow of oxygen and how long will the portable unit last without a refill
I make liquid air in my basement with a cryocooler :)
Once in a while, I let the liquid nitrogen boil off so I can play with the liquid oxygen that remains. I have a video of paper shooting flames like a flare after being soaked in LOX. It's fun stuff!
Very interesting
Thank you
I've just been put on LOX and have a skin of ice on the exterior from the dial down to the bottom. Does anyone know what to do or why this is happening? The folks at my MDE company didn't know.
from were can I get same machine?
How can I get one like that,,,is it loud, my oxygen tank is so loud I have a headache,,cannot sleep?what can I do??
If on a setting is on 2 L C flow what is the time on it
Hi, I was wondering when the patient wants to use the portable canister and turns on the flow rate, should the canister then have vapour around it while in use? is there any dangers to that vapour? thanks.
Hi: It depends. If there is moisture between the portable canister and the reservoir during filling, its possible that the vapor could be oxygen vapor so the usual oxygen safety precautions should be employed. Another possibility is that the vapor is just moisture that condensates as the canister filled (the components of it exposed to liquid oxygen are now super cold0 so a mist occurs.....especially in humid locations....it would be like taking something out of the freezer on a really hot summer day and watching the mist come off of it. Hope this helps.
The vapor that you are speaking about should disappear after awhile as the unit warms up. If you are in a hot and humid area, It could have a small amount of vapor coming off of it for quite awhile. When its hot and humid where I live and I pull a tray of ice cubes out of the freezer, there is usually a humidity vapor coming off of it.
The vapor itself (under normal conditions) is just room air humidity. However, if your unit is leaking, it could be liquid O2 vaporizing. If your concerned, please have your service provider check it. Hope this helps
What does it mean when it starts making a loud whining noise after being filled? Ours are not in the best condition, they drip all of the time. Some of the portable tanks wont stay on the refill adapter at all they tend to pop off. Sometimes they will leak vapor after filling up, i believe that might be from getting frozen open a little bit.... please help me out. My facilities tanks are not in ship shape condition and so as of right now Im a little apprehensive about filling them.
It would be hard to pin point what it is without being there and hearing it. However, that sound could be gas escaping from the fill valve at the bottom of the unit or it could be from a pressure release valve inside the unit. Both can occur with filling. If your unit is older its probably prone to some leaks, but those sounds should end and the dripping should stop. Any moisture by the fill valve will also create problems like that by freezing open (the fill valve) when exposed to the cold liquid.
Try to ensure that the fill valves/connectors on the portable and the reservoir are both dry prior to connection and filling. Once connected, you may have to hold on to the portable while filling to prevent liquid from escaping.......not the best situation. Also make sure that your wearing the proper safety gear like, safety shield, proper gloves or mitts and long sleeves. Remember that liquid O2 is around -180 C and frost bite can occur quickly.
If in doubt, get a service technician to check it so that its safe for you and your patients to use.
What uses does liquid oxygen have in the medical field? Is it just more convenient to store instead of pressurized? I always thought the pressurized oxygen canisters has liquid in them…
No, you can't liquify oxygen under room temperature conditions so the compressed gas needs much more volume. One liter LOX turns to 800 liter gas under normal conditions. A 1 liter gas cylinder with 200 bar can only deliver about 160 liter.

What is the PPE (if I’m hearing it correctly) cloth? What’s “PPE”?
Hi: Personal Protective Equipment......heavy gloves, face shield etc to protect a person from injuries when handling liquid O2
Personal Protective Equipment: pretty much safety gear you would wear to protect yourself.
Personal Protection Equipment (Gloves, Safety Glasses and such.)
which part do you call the durer
Dewar?! This is the thermal insulated storage tank.
