The document discusses POLST (Physician Orders for Life-Sustaining Treatment), which is used to document patients' end-of-life treatment preferences. It outlines a series of questions asked of patients to determine their goals of care, including whether they would want CPR if their heart stopped or life-sustaining treatment if their lungs and heart could no longer provide oxygen to their organs. Answers to these questions determine the appropriate treatment options selected on the POLST form. The POLST is then signed by the patient and healthcare provider to document the patient's wishes.
