The investigators plan to investigate the effect of attention distractor on the quality of chest compression during cardiopulmonary resuscitation. For this, a simulated study with Manikin is performed and the paced auditory serial addition test (PASAT) is used for distracting performer's attention.

adequate compression rate
the percentage of chest compression with adequate rate (100-120 per minute) during two-minute chest compression. Formula(%)=number of adequate chest compressions (rate:100-120/min) x 100 / number of all chest compressions during two minutes
Time frame: two minutes
adequate compression depth
the percentage of chest compression with adequate depth (5-6cm) during two-minute chest compression. Formula(%)= number of adequate chest compressions(depth=5-6cm)x 100 / all chest compressions during two minutes
Time frame: two minutes
adequate chest recoil
the percentage of chest compression with adequate chest recoil during two-minute chest compression. Formula(%)=number of adequate chest recoils(automatically measured with simulator) x 100/ number of all chest compressions during two minutes
Time frame: two minutes
mean compression rate
Average of compression rate during two-minute chest compression. The scale for this outome is 'number per minute'.
Time frame: two minutes
mean compression depth
Average of compression depth during two-minute chest compression. The scale for this outcome is 'cm'.
Time frame: two minutes
Subjective difficulty
Each performer rate the subjective difficulties of two arms with the 100mm VAS (0: very easy, 100: very difficult)
Time frame: Two minutes
