Resuscitation in pregnancy

Primigravida, 38th week of pregnancy, is admitted to the maternity ward of regional hospital with regular uterine contractions every 4 minutes. The membranes break spontaneously. Cervix is dilated at 3 cm. A gynaecological examination and ultrasound is normal. The patient is transferred to the delivery room. Anaesthesiologist provides epidural analgesia. Labour progresses more after the first bolus to epidural catether (0.125 % levobupivacaine 9 mL + sufentanil 5 μg). During the last examination a midwife measured dilation of cervix 7 cm.

Suddenly partner calls a midwife, because woman doesn't react to any insults. An obstetrician comes and diagnoses cardiac arrest. What should obstetrician do next?
