Patients with terminal illness or end of life who are treated in intensive care rooms (ICU) such as respiratory failure, loss of consciousness, organ disorders, and sepsis are often difficult to release from life support. The act of sustaining life is carried out by providing life support devices and pulmonary resuscitation (RJP), while the act of releasing life assistance means not doing resuscitation or releasing the use of life support devices. This study aims to find whether there is a relationship between patients who are given life support measures in the form of mechanical ventilators with the incidence of CPR in patients before dying in the ICU. Data is taken from the medical records of patients who died in ICU Yogyakarta PKU Gamping Hospital in 2017-2018. The results showed that there was no relationship between patients using ventilators with CPR (p> 0.05). In this study there were patients who did not do CPR, but could not be followed because no CPR was performed because of data limitations.
