Generally speaking, you will be detailing decisions regarding the use of emergency treatments to keep you alive in the event of a tragedy, such as CPR, artificial hydration and nutrition, comfort care and the use of a ventilator. To further detail these very specific decisions, you might want to consider a Physician Order for Life-Sustaining Treatment (POLST) Form, which is a medical order for specific medical treatments you would want during a medical emergency. A POLST form is not a substitute for an advance health care directive, rather can work in conjunction with the directive and is particularly appropriate for those with a serious illness or advanced frailty.
