Chen Ge removed his shirt, and the two nurses helped him apply the audio recorder and heartrate monitor. After testing, several fluctuating lines appeared on the screen in the middle of the hall. The man stood to the side of the stage and pointed at the lines. "HR/PR represents heartrate and pulse rate. SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen in the blood. RESP is respiratory rate. TEMP is body temperature. Based on these few lines, we can clearly and objectively see the change in your emotions."
After putting on his clothes, Chen Ge shrugged. "Can we start now?"
"The entrance is to the left of the hall; the exit is on the right. We'll wait for you at the exit," the man explained briefly to Chen Ge. "There is a guide inside the Haunted House, so he'll tell you what to do."
