Conceptually the sloping sides of the funnel of the Vortex represent the potential for deteriorating SpO2 if alveolar O2 is not restored. When ventilation is interrupted in a patient with shunt physiology this descent would be more precipitous, and (theoretically) less so with ApOx.

Nicholas Chrimes @chrimesy.com · 17/04/2026
Correct. Whereas ApOx w HFNO (in patients without shunt physiology) would make the sides less steep.

Should we use fewer arterial catheters in critical care patients? It may prevent harm from non-infective and infective complications, lower financial and environmental costs and reduce iatrogenic blood loss and blood transfusions in individual patients. #AnSky #ICUSky doi.org/10.1111/anae...

Pity they massively overdosed the ketamine arm - significant percentage > 2mg/kg / no ceiling dose ("rule of 1 ampoule") / dose per total body weight / and who gives > 0.5 mg/kg to a "sick" patient - great trial / wrong pharmacology / wrong conclusion = drugs are equivalent at equipotent doses

The term ‘TIVA’ is irrelevant to what’s being discussed. The question is should you deliver the induction meds for RSI through a syringe pump. The answer is no (until we get pumps that can deliver at 7200ml/hr).

Nicholas Chrimes @chrimesy.com · 29/11/2025
“TIVA RSI” (whether pump assisted or not) is a stupid term. What makes the anaesthetic TIVA is whether IV agent is used for throughout. All RSI inductions are IV but many are not TIVA bc a volatile is subsequently given for maintenance. It’s just pump assisted RSI.

Nicholas Chrimes @chrimesy.com · 29/11/2025
Specifics have evolved. Principles remain the same. I think the biggest issue w RSI is its binary nature. If someone is ‘at risk’ of aspiration, they get RSI even if elements of the technique (eg. no latency bw IA & NMBA) might cause them harm. Amounts to aspiration trumping all other concerns 🤔

Though there are plenty of other reasons to intubate head up.

Nicholas Chrimes @chrimesy.com · 15/11/2025
Steep head up decreases the risk of regurgitation but increases the risk of aspiration if regurgitation does occur. Conversely, steep head down makes regurgitation more likely but aspiration virtually impossible in an apnoeic patient. It’s a zero sum game. You can argue it either way.

Nicholas Chrimes @chrimesy.com · 15/11/2025
If you’re not going to use cricoid, you shouldn’t be doing RSI at all, just standard intubations on everyone.

Nicholas Chrimes @chrimesy.com · 15/11/2025
No one has shown *in a randomised controlled trial* that it does what they say it will do (which is true of all components of RSI) but there’s lots of other experimental evidence that it blocks passage of material bw stomach & pharynx (whereas no other component of RSI has any evidence at all!).

This one’s for @drmikeclifford.bsky.social Cricoid pressure has been selectively vilified out of RSI in many settings, yet it has less risks, a better rationale & more evidence for efficacy than any other cited component of RSI Why aren’t we doing it routinely for all adult tracheal intubations?
