I am out and about most days with my portable LOX and love the freedom it gives me. However, this week, in this lovely autumn sunshine, I was out in my garden pruning the shrubs ready for winter. All went well for about half an hour until I suddenly felt very breathless. I realised I wasn't getting any oxygen so I stopped, fiddled with the control knob and tube connections, took my cannula out and checked it was clear and only then saw what I had done. I had grabbed my tubing in with a bunch of foliage and cut clean through it with my secateurs. Thanks to Air Products I had spare tubing so, after gasping then giggling I was able to continue my lovely afternoon in the sunshine
