Mae hyn er gwaethaf pwysau aruthrol. Er enghraifft, atebodd gwasanaeth GIG 111 Cymru fwy o alwadau ffôn nag erioed, a'r nifer cyfartalog o alwadau coch y dydd a wnaed ym mis Rhagfyr oedd yr ail uchaf erioed.
This is despite immense pressure. As an example, the NHS 111 Wales service answered more calls than ever, and the average number of daily red calls made in December was the second highest on record.
