Dear Carol Ann,

'Pediatric' refers to low flow rate, not to how they attach to a tank.

So you probably have a CGA 540 (stem and nut weld type) pediatric flow rate

and

a CGA 870 (pin index) flow rate unknown.

You cannot use a regulator on a concentrator.

But you can use an outboard flow meter to control the output of your

concentrator, PROVIDED that your concentrator will not quit when the flow

rate is restricted (which all modern ones are designed to do).

You can get an outboard flow meter from

http://www.phc-online.com/

They sell the Invacare Precise Rx Pediatric Flowmeter for $192.50

It is controllable down to 1/16 l/m.

Best of Health!
