The Effect of Attention Distractor on the Quality of Chest Compression

Study Overview
=================
Brief Summary
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: CPR with attention distraction first<br>First, they perform two-minute chest compressions with conducting the PASAT. After 20 mins' rest, they perform two-minute chest compressions without conducting the PASAT. | Other: paced auditory serial addition test (PASAT)<br>* A number between 1 to 9 is called every three seconds through a speaker, and the performer calculates the last two numbers and shouts the answer.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | two minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | 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 | two minutes | 
| mean compression rate | Average of compression rate during two-minute chest compression. The scale for this outome is 'number per minute'. | two minutes | 
| mean compression depth | Average of compression depth during two-minute chest compression. The scale for this outcome is 'cm'. | two minutes | 
| Subjective difficulty | Each performer rate the subjective difficulties of two arms with the 100mm VAS (0: very easy, 100: very difficult) | Two minutes |
