Mae'r math o therapi dwys a ddarperir yn golygu fod gwelyau gofal critigol yn un o adnoddau drutaf y gwasanaeth gofal eilaidd.  Er enghraifft, mae gwely lefel tri tua 4½ gwaith yn ddrutach na gwely mewn ward gyffredin. Felly, pan ddaw cyfnod o ofal critigol i ben, mae'n bwysig bod cleifion yn cael eu symud cyn gynted â phosibl i amgylchedd sy'n fwy priodol er mwyn eu hadsefydlu a diwallu eu hanghenion.
The nature of the intensive therapy provided means critical care beds are amongst the most costly resource within a secondary care service.  For example a level three bed is about 4½ times more expensive than a normal ward bed. Therefore, when a “critical care episode” is complete, it is important that patients are moved on to an environment more appropriate for their needs and rehabilitation as soon as possible.
