Pediatric POCs

Hello everyone I phoned BOC today lady said the smallest they do is what I have the the Z4 I think she said, they are the canisters I have mine in a shopping trolley, plus I have the Inogen G3 curtesy of NHS which I am grateful for. These others I think I saw in a post are even lighter but only last for an hour, but for exercise that's all I want ... I can never last the 3 hrs on my G3 anyway the stamina is not there ... any ideas. Sam

The Z4 is equivalent to others at around 2.2/2.7kg.

BOC do liquid oxygen with a flask weighing 1.63kg.

Does require more effort and you need a place to store main Dewar.


Thankyou Stone
