intubation sequence

[Timothy J Coats (SURG) 7728]

An I teaching incorrectly?

I was interested to see a mention of jet ventilation using an ambu 
bag. I have allways taught that at least a 50psi pressure oxygen 
source is required to oxygenate (not ventilate) through a needle cric. 
I have no experience of using a needle (always do a surgical!). Does 
ventilation with an ambu bag through a needle actually make the 
chest move?

Anyone have actual (rather than theoretical) experience?

Tim.

> Just curious if your home made crico set-up is anything like 
mine?  I use a 3cc syringe, remove the plunger and needle and 
attach the adapter from a size 7.0 ETT.  This fits PERFECTLY into 
the syringe barrel and can then be ventilated with ambu or 
mechanical (although may get high inspiratory  
pressure alarms) or can hook up to a jet ventilator.  Works great in 
a pinch and buys you some time (albeit, limited). > Andrew J.
