Cardiopulmonary resuscitation performance.

	Conventional group; (48 teams)	Video call guidance group; (48 teams)	p-value
Accurate D/C shock			1.00
Yes	48 (100%)	48 (100%)
No	0 (0%)	0 (0%)
Time to 1st defibrillation (seconds)	73 (59.75~90)	56 (44~74.25)	<0.001
Time from last compression to defibrillation (seconds)	8 (3~19)	3 (2~7)	<0.001
Time from defibrillation to chest compression (seconds)	3 (2~4)	2 (1~3)	<0.001
Total CPR time (seconds)	704.5 (674~740)	686.5 (663~706.2)	0.004
Total hands-off time (seconds)	285.5 (299.75~339.0)	228 (192.75~270.25)	<0.001
Hands-off ratio (total hands-off time/total CPR time (seconds)	0.41 (0.33~0.47)	0.32 (0.27~0.38)	<0.001

The values (except accurate D/C shock) are presented as the median (interquartile range).
BLS: basic life support, D/C: direct current, CPR: cardiopulmonary resuscitation.
