Looking forward to the article!
Pretty darn cool! Although I think it will blow some minds that a nasal cannula can be used at rates of up to 15 lpm 🙂
Levitan and Weingart making emergency airway management safer the world over!
You guys rock!
Thanks from down under.
I used these principles on my last severe pneumonia case recently…she had SaO2 88% on 15Lmask. with CPAP and nasal cannula ..she was100%….during the whole RSI ..she never dropped lower than 98%
It works
believe
Nice video Scott,
I love PEEP valves on my BVM. Adding NPO2 @ 15lpm is a great touch.
On a side note, I’d be drawing a distinction between my resus patient exhaling and “expiring”. Context, context. :>)
Take care
Matthew
I read your annals paper with great interest.
The table “Sequence of Preoxygenation and Prevention of Desaturation” seems to specifically indicate the nasal cannula should not be connected to oxygen during the preoxygenation period. This appears to be discordant with the video – and as you nicely explained would lead to PEEP only being provided during expiration. Can you please clarify why that was included in your paper?
Thank you
Great review article, would like to incorporate this method into our pre-hospital RSI program to buy us more safe apnea. Wondering if there is a concern for denitrogenation-related atelectasis with this method and if so how much of a concern would it really be?
Thanks for a great resource!!
The fact that we are using CPAP makes atelectasis far less likely.

Hey Scott, I was wondering if this is true if you are using flow inflated bags instead of self-inflated bags, We use anesthesia bags in our department, and I’m thinking that because we have constant flow (no actual expiration vale) on these bags that they provide constant PEEP. Is that an accurate assumption?
yes it is. I did a discussion on Mapleson Circuits as one of the wees. Problem is most are non-calibrated and I think rebreathing increases with PEEP on these bad boys.
