B means to establish breathing and increase ventilation.
C is to maintain normal circulation and maintain adequate cardiac output. The position of pressing is under the sternum 1/3, and the frequency is 90 times/minute. Every three compressions, the positive pressure ventilation is 1 time, and the compression depth is 1/3 of the anterior-posterior diameter of the thorax.
D is drug therapy: 1: 10000 epinephrine can be administered intravenously or intratracheal; In addition, there are drugs such as dopamine or dobutamine.
