The indication for a cricothyrotomy is a "cannot intubate, cannot ventilate" situation.[1]

Step 0

The first step is to gather the needed equipment. This includes a scalpel, a bougie, a 6-0 endotracheal tube, and a 10 cc syringe.

Step 1a

Feel the laryngeal prominence (Adam's apple) of the thyroid cartilage.[2]

Step 1b

Than move about 2 centimeters lower on the neck into the depression representing the cricothyroid membrane, after which is the cricoid cartilage.[2] Some recommend finding the sternal notch than moving up.[3]

Step 2

Stabilize the neck and make a 4 centimeter vertical cut through the skin over the cricothyroid membrane.[2]

Step 3

Blunt dissect with fingers down to the cricothyroid membrane.[2]

Step 4

Cut with the scalpel across and through the cricothyroid membrane and place your finger through the hole.[2]

Step 5

Pass the bougie through the hole guiding it inferiorly.[2]

Step 6

Pass a 6-0 cuffed endotracheal tube over the bougie.[2]

Step 7

Inflate the balloon, then bag valve mask with end tidal CO2 attached.[2] Than secure the tube.

Step 8

Finally verify depth of placement of the endotracheal tube on chest Xray.
