Criteria for Not Starting CPR: Scientific evaluation has shown that there are no clear criteria to predict the futility of CPR accurately. Therefore, it is recommended that all patients in cardiac arrest receive resuscitation unless; 1. The patient has a valid DNAR order. 2. The patient has signs of irreversible death: rigor mortis, decapitation, or dependent lividity.
3. No physiological benefit can be expected because the vital functions have deteriorated despite maximal therapy for such conditions as progressive septic or cardiogenic shock. 4. Withholding attempts to resuscitate in the delivery room is appropriate for newly born infants with Confirmed gestation <23 weeks or birthweight <400 g Anencephaly,Confirmed trisomy 13 or 18
