Number of central vein puncture trial	up to 5 times, an expected average observation time of 30 seconds
Time to first puncture of central vein	Interval between skin penetration of the needle and flashback of blood, an expected average of 30 seconds
First successful central vein puncture rate	Interval between skin penetration of the needle or angiocatheter and flashback of blood, an expected average of 30 seconds
