A “resuscitate-tag” is almost the same as an usual dog-tag. The only difference between those two tags is the special personal message that’s punched into a resuscitate-tag; “do not resuscitate”.
The tekst will be punched into a stainless tag. This ensures the tekst is indelible.
Pay attention! To put the tekst: “do not resuscitate” on your tag is your own choice. In all probability, a rescuer won’t resuscitate you if you’re wearing it.
Of course, you can also put some other personal and medical information on the tag.
