1.If you cannot see the vocal cords or epiglottis after positioning the laryngoscope blade, you have probably inserted the blade too far or have not placed the blade precisely in the midline.
如果在调整好喉镜窥视位置后,不能观察到声带或会厌,可能是由于窥视插入太深或未能将其精确地放置于正中线所致。收藏指正
2.Withdrawing the blade gradually in the midline will often allow the epiglottis or larynx to drop into view.
慢慢地在正中线退出窥视,经常可以使声带或会厌跃然出现于视野中。收藏指正
