Dr. Jessica Mason reviews the setup for percutaneous transtracheal ventilation. In this technique we use the angiocatheter from a central line kit (not a standard angiocatheter for peripheral access), a 10 cc flush, a 3 cc syringe with the plunger removed and the connector from a 7.0-7.5 ET tube inserted into the 3 cc syringe. With the flush attached to the angiocather, enter the cricothyroid membrane at 45 degrees aiming caudally while aspiring. When you see bubbles in the syringe you are in the trachea. Advance the catheter over the needle and remove the needle. Connect the angiocatheter to the 3 cc syringe with the ET tube connector. This allows you to attach a bag-valve and bag the patient. Many standard angiocatheters do not have a Luer lock connection so cannot connect to the syringe, and also have a filter at the top, so these should be avoided. This technique was described by Dr. Ilene Claudius in the C3 episode on Pediatric Airway.
