I also work in healthcare. There are legal documentd that can seriously help here as well. Living will, DNR, advance directive, and medical POA for example.

As a fellow Christian i also find this topic important. All heathcare, but especially end of life care is aiming limited resouces (all the docs, nurses, meds, proceedures, beds etc) at an infinate problem... death.

At some point we MUST cease trying to preserve life at all costs. But technology continues to extend that ultimate limit.

"Just because we can" is a terrible and sometimes hellish driver.
