An ambulance was just a mobile emergency treatment facility.
The procedures that could be performed in it were limited.
Zheng Ren had set up a simplified version of a closed chest drainage system to ensure the patient's breathing was unobstructed and that she would not die of pneumothorax. He then used the suction tube to remove blood from her upper airway to prevent it from clotting, which would result in blockage of her airway.
On top of that, he applied pressure onto Yang Lili's stab wounds on her abdomen to reduce bleeding.
Faster! Faster!
Zheng Ren kept urging the ambulance driver on.
Sea City General Hospital and No. 9 Elementary School were not that far apart, but the thick metallic scent of blood heightened Zheng Ren's anxiety.
The ambulance would normally be unable to drive at such speed even with its sirens at maximum volume.
