I don’t have evidence for this, but it seems to be true:
🌪️ when patients need HFNC to help clear CO2, they find it comfortable (or at least tolerable)
🌪️ when patients get better and don’t need HFNC, they find it annoying and pull it off
so you can sometimes titrate to comfort 🤷♂️ #EMIMCC

A reminder this viral bronchiolitis season, more is not always better! Consider that high rates of HFNC may be making the baby more distressed.

1) agree with Damien - short term trial may be OK. Then see if you can wean to HFNC
2) COPD plus pneumonia pts can do well with a strategy of flipping back and forth between HFNC & BiPAP
3) Pure pneumonia and totally dependent on BiPAP for more than a few hours (cannot tolerate HFNC) ➡️ tube

Another thing I hear often in the ICU is this:
The patient is on high-flow nasal cannula (HFNC) (or high-flow oxymask)
When I specifically ask "how many liters?", often the answer is: 6 or 7 l/min
HFNC is a respiratory support system delivering heated-humidified O2 @

patients who intentionally self-extubate can often stay off the ventilator (eg using BiPAP or HFNC support).
when in doubt: stop all sedatives, support noninvasively, and watch really closely.
not ideal but this happens & often ends well 🤷♂️

Should we worry about re-expansion pulmonary edema (RPE)?
-Very uncommon(1-3% of drainages)
-Rapidity/completeness of drainage irrelevant
-Look for anterior chest discomfort, tachycardia, hypoxemia + tachypnea
-Tx:l O2 (NC, HFNC, NIV) + slow drainage
