地方热点:珠海调度电话里的生命接力
It was a busy afternoon in Zhuhai. 1 two families facing life-and-death emergencies.
At 5:48 p.m., Xiaoling's father suddenly fell down in the living room. His face 2 pale, and he stopped breathing. Xiaoling was scared. She called 3 help, crying, "My father isn't moving!" On the phone, the emergency operator(调度员), Shou Xiaotao, spoke calmly, "Push hard on the middle of his chest(胸部)—fast!" With shaking hands, Xiaoling followed the instructions —30 pushes, then tilting(倾斜) his head back to give 4 air. "You're doing great," Shou encouraged. Eight minutes later, the ambulance arrived. The doctors used a machine 5 his heart beat again. Later, a doctor told Xiaoling, "Your quick 6 saved his life."
Just after sunset, another emergency happened. At 7:31 p.m., Grandma Li suddenly coughed and then stopped breathing. Her grandson, Hao, shouted into 7 phone, "She's not moving!" The operator, Chen Jiajun, guided him: "Press hard on her chest." Hao counted as he pressed. When the ambulance came, Grandma Li was not awake, but the doctors saved her.
Both stories show a 8: When someone's heart stops, the first four minutes are the most important. Xiaoling and Hao had never learned CPR(心肺复苏) before. With the 9 help, they became heroes. "I just did 10 he told me," Xiaoling said later, holding her father's hand. In those moments, courage, a calm voice, and four minutes can change everything.
