简要总结
The purpose of this study is to evaluate the variations of respiratory changes in pulse oximeter plethysmographic amplitude (delta POP) according to different contact forces between finger and sensor of pulse oximeter. During general anesthesia without surgical stimuli, pulse oximeter sensor is applied with serial contact force, from 0 to maximal 1.5N (increased by 0.2N) and POP waveform is obtained for 60 seconds. Delta POP will be calculated and compared.

研究组 & 干预措施
Children under general anesthesia
During general anesthesia without surgical stimuli, pulse oximeter sensor is applied with gradually increased contact force, from 0 to maximal 1.5N (increase by about 0.2N), at an index finger and POP waveform is obtained for 60 seconds at each contact force. Delta POP will be calculated and compared.
干预措施: Applying pulse oximeter sensor (Other)
