I've used all three, plus in-wall units. To me, concentrators seemed the easiest to work, but were always breaking down and needing repairs. So we search & search & search for replacement units. If you've a LARGE number of pts needing O2, will you have enough? If power goes out, where will you plug in? Where will you store/park extra machines? And you will need a cleaning schedule to include the nasty dusty filters! MY biggest pet peeve with concentrators was that there were never enough electirc sockets to accomodate the concentrator & IV pump & GT pump & nebulizer & CPM machine & electric bed (laptop plug, cell phone charger, cd player, personal fan)etc. GET THE IDEA?!?! And then if the roommate has equip also!
Big tanks were a nuisance r/t size & being awkward in the room, and then unit and central storage were problematic. Who will bring them to the floor? Will deliveries be sufficient if there's a large usage? And the need for WORKING REGULATORS? You need sufficient supply of them and staff need to be knowledgabe in the assemby (not always easy). Tank dollies, too.
Those little battery ones and/or liquid oxygen rechargeables last only briefly, but they are good for whch trransport and off-unit activities. Not long term use. Again, someone must be responsible for recharging them. Also, they empty out silently so your pt is on room air!
In-wall units were no-brainers but that was preplanned into the building of the walls They were a luxury! But flowmeters were a scarcity.
As supervisor in various LTC facilities, I've done them all in different combos. The time & energy I've spent making sure my units were covered could be horrendous some nights. I've faced all the problems I mentioned. Some employers rose to the challenges and worked to make the system work. And others...(let's not go there!). But with mgt accomodating the system, I personally would choose concentrators with big tank availability for quick use. Just my
