Question 3
Question
A cricothyroidotomy should be performed if the airway can't be achieved by other means. In children under [blank_start]12[blank_end] years a needle is preffered (surgical offers better protection in older children). A [blank_start]5[blank_end]ml syringe should be attached to a cannula. Tubing should be connected to a [blank_start]Y[blank_end] connector; flow = patient's [blank_start]age[blank_end]. Increase flow by [blank_start]1[blank_end]l if chest not moving. Thumb off for [blank_start]4[blank_end] seconds to allow for expiration.
