shoutout to @mdcalc - measure height and use formula to obtain TV #StoweEM20 by @mattroginski
dont stress about the etCO2 81 - hypercapnia wont kill the patient. trying to achieve a normal pCO2 might 💀 (dynamic hyperinflation causes obstructive shock) . #StoweEM20 by @mattroginski ImageImageImage
autoPEEP can be measured, but this requires a passive patient. waveforms provide qualitative information even if not passive #StoweEM20 by @mattroginski ImageImage
the primary driver of autoPeep is respiratory rate (*not* tinkering with the inspiratory time). shoot for resp rate around 10-14 #StoweEM20 by @mattroginski ImageImage

Critical interactions for the critical care cardiologist: An anthology of the tortured pharmacist's department

@TaniaAhuja who should get AV nodal blockers?

Diltiazem is contraindicated in shock.

**If you don't know the EF, may avoid.**

Diltiazem and riveroxiban may interact as well.

Low slow and trying to crash

CCB & Bbl intoxication.

Getting things done is tough! A really sick CCB/BBl intoxication challenges this.

@emcrit Start with calcium, although it probably don't do a ton. May follow this with a calcium infusion if there is sufficient IV access.

Why do I deviate from ACLS?

- @mdonnino at #critcarecards24 Image
@mdonnino Do you resume CPR after shock? Yeap.

In 2005 the algorithm changed from stacked shocks to a single shock followed by waiting for 2 minutes to see what is going on.

No solid evidence that this was the correct approach.

- @mdonnino at #critcarecards24 Image
@mdonnino Years after implementation: the new approach actually seemed to cause worse outcomes (not statistically significant)

More on RV failure:

Acute RVMI: loading can be helpful because we want to raise the RV pressure higher than the PA pressure to cause blood to flow downhill.

- @Chrisotpher Barnett at #critcarecards24 Image
Image
Chronic pulmonary artery hypertension: RV is *chronically* adapted

Volume loading may help push patients into the RV death spiral.

- Chrisotpher Barnett at #critcarecards24 Image
Image
In chronic RV dysfunction, function may often be optimized by fluid removal.

this may additionally avoid systemic congestion!

1st talk: RV dysfunction by @Sam_Brusca at #critcarecards24

RV contracts in multiple mechanisms.

LV contraction indirectly contributes 40% of the stroke volume of the RV! Image

- RV-PA coupling may fail with RV dilation, but this is difficult to assess at the bedside

- @Sam_Brusca at #critcarecards24 Image
Image
PAPI as a marker of RV-PA coupling!

cutoff may depend on context

RV MI: unconditioned PAPI decouples at <1

PAH: PAPI cutoff for worse outcomes may be higher Image

how to place a consult: you MUST understand the five stages of consultant grief.

once you can understand this painful and natural process, requesting consults will make a LOT more sense

buckle up, it can be a little rough…

🧵 1/6…
stage 1: denial

- You dont need a consult.
- You called the wrong service.
- 18 years old? consult pediatrics
- I’m not actually on call now
- Everything’s fine, just walk it off…
stage 2: anger

- you should have consulted us earlier/later
- you should have checked this test before calling us
- you’re a terrible doctor/student/human being
