At the moment the government are saying all of our hospitals do have capacity (albeit some less than others). We have thousands more beds being created in the field hospitals and 7000+ vents available. I don’t think doctors are having to choose which person to save just yet (which is only based on when there is a lack of equipment). If you turn up needing treatment and they can provide it, they absolutely will. A DNR also doesn’t mean you won’t be treated, it means if you die during that treatment they won’t try to bring you back. A very different reality to what the media (again) are painting - that doctors will overlook your 90 year old gran for the 30 year old in the bed next to her. IF there is a lack of equipment (which the government are indicating we are far from facing), then they’ll make that heartbreaking choice which they sometimes have to do even without a pandemic though I suspect not too often. If your hospital has capacity and regardless of a DNR, everyone WILL be treated.
