English: Well, I'm pleased to hear the oxygen flow issues are being addressed and are being highlighted, and that's, of course, important. It's partly, though, because of the flexing up of critical care capacity and the much greater use of oxygen, and so the flow that's required has obviously increased. That's not a surprise when we think about what's happening. In terms of investing in that work over a period of time, well, as we learn lessons, not just at the end of this but all the way through this, we'll of course have questions to ask about what we have done but then more importantly what we choose to do in the future for our preparation, not just for a potential future pandemic, but actually for what we think of as normal business and what level of resilience we need. And that's quite a difficult debate, actually, because that is about how we use resources and how we spend money prospectively when, actually, we've gone through a period of more than a decade where, actually, it's been about a deliberate policy to take money out of public services, and we've all had to cope with a significantly reduced amount to do that with. On your final point about whether this means that Ysbyty Gwynedd is being downgraded, I simply don't agree with you. There is no secret plan to downgrade Ysbyty Gwynedd and to do it secretly and quietly through the back door, so I'm happy to reassure you that this isn't the plan of either myself or anyone else. The reconfiguration of health services right across the country is about how we design what works best within our health and care system and how we meet the challenge set for us by the parliamentary review that set out that, on some services, we could and should see a better service with better outcomes for people if we concentrate those highly specialist areas, but equally on others, they should move out of specialist centres either into local provision or, indeed, primary and community care. That is the basic plan that we have right across the country, and it's really important that we reflect that that is the best way to deliver the best possible care to each of us and that's the way we could and should organise our system.
Welsh: Wel, rwy'n falch o glywed bod materion llif ocsigen yn cael sylw ac yn cael eu hamlygu, ac mae hynny, wrth gwrs, yn bwysig. Mae'n rhannol, serch hynny, oherwydd y cynnydd yn y capasiti gofal critigol a'r defnydd llawer helaethach o ocsigen, ac felly mae'r llif sydd ei angen yn amlwg wedi cynyddu. Nid yw hynny'n syndod pan ystyriwn yr hyn sy'n digwydd. O ran buddsoddi yn y gwaith hwnnw dros gyfnod o amser, wel, wrth inni ddysgu gwersi, nid ar ddiwedd hyn yn unig ond drwy hyn i gyd, wrth gwrs bydd cwestiynau i'w gofyn am yr hyn a wnaethom ni ond yn bwysicach na hynny, yr hyn y dewiswn ei wneud yn y dyfodol i baratoi, nid dim ond ar gyfer pandemig posibl yn y dyfodol, ond mewn gwirionedd ar gyfer yr hyn a ystyriwn yn fusnes fel arfer a faint o gydnerthedd sydd ei hangen arnom. Ac mae honno'n ddadl eithaf anodd, mewn gwirionedd, oherwydd mae a wnelo hi â sut yr ydym yn defnyddio adnoddau a sut yr ydym yn gwario arian yn rhagolygol a ninnau, mewn gwirionedd, wedi mynd drwy gyfnod o fwy na degawd pryd, mewn gwirionedd, mae wedi bod yn ymwneud â pholisi bwriadol i gymryd arian allan o wasanaethau cyhoeddus, a bu rhaid i bob un ohonom ni ymdopi â gostyngiad sylweddol i gyflawni hynny. O ran eich pwynt olaf ynghylch a yw hyn yn golygu bod Ysbyty Gwynedd yn cael ei israddio, nid wyf yn cytuno â chi. Does dim cynllun cyfrinachol i israddio Ysbyty Gwynedd ac i wneud hynny'n gyfrinachol ac yn dawel drwy'r drws cefn, felly rwy'n hapus i dawelu eich meddwl nad yw hyn yn gynllun gennyf i nac ychwaith gan unrhyw un arall. Mae'r broses o ad-drefnu gwasanaethau iechyd ledled y wlad yn ymwneud â'r ffordd yr ydym yn cynllunio'r hyn sy'n gweithio orau o fewn ein system iechyd a gofal a sut yr ydym yn ateb yr her a osodwyd inni gan yr adolygiad Seneddol a nododd, mewn rhai gwasanaethau, y gallem ac y dylem weld gwasanaeth gwell gyda chanlyniadau gwell i bobl os canolbwyntiwn ar y meysydd arbenigol iawn hynny, ond yn yr un modd ar eraill, dylent symud allan o ganolfannau arbenigol naill ai i ddarpariaeth leol neu, yn wir, i ofal sylfaenol a chymunedol. Dyna'r cynllun sylfaenol sydd gennym ni ledled y wlad, ac mae'n bwysig iawn ein bod yn nodi mai dyna'r ffordd orau o ddarparu'r gofal gorau posib i bob un ohonom a dyna sut y gallem ac y dylem drefnu ein system.
