NCT02088879

Brief Summary

The chest compression depth decreases over time after starting continuous chest compression due to the rescuers' fatigue. The investigators hypothesized that the frequency parameters from surface electromyogram from each muscle during chest compression may reflect the muscle fatigue of the rescuers. Then investigators can identify which of the body are mainly used and get tired by continuous chest compression using surface electromyogram.

Outcome Measures

Primary Outcomes (1)

  • median frequency of electromyogram

    median frequency of electromyogram in 16 muscles during chest compression The muscles are flexor carpi radialis, extensor carpi radialis, biceps brachii, triceps brachii, deltoideus, erector spinae (cervical area), trapezius, rhomboid, erector spinae (thoracic area), erector spinae (lumbar), obliquus externus abdominis, rectus abdominis, pectoralis, quadriceps femoris, biceps femoris, gastrocnemius. On the dominant side of the rescuers, we will attach sixteen electrodes on these muscles.
