This is fascinating. Never knew this could happen but makes sense.

Old school diuresis monitoring in RV failure? 📉 Daily weights + strict I&Os = cornerstone… but recent evidence disagrees! they’re often inaccurate & slow to obtain. 😩 Upgrade your game: Check UOP goal + electrolytes q6h in first 24h, then q12h. Even better: spot urine Na

ACUTE RVF AND FLUID STEWARDSHIP: There has been a traditional teaching that hypotension in acute RVF should be treated first with a trial of small IVF bolus. In my recent review I argue that this 'traditional teaching' should be reserved for rare cases of clear hypovolemia. The

Pressure Volume loops have so much great physiology! I built a little app to simulate cardiac PV curves and demonstrate how different MCS devices (IABP, Impella, VA-ECMO) alter them. Try it out: nickmmark.github.io/pressure-volum… I'd love to hear your feedback & ideas for improvement!

Pulmonary and critical care medicine lives where physiology meets judgment. It is a field defined by high-acuity care and the need to balance evidence, experience, and ethics in real time. The work is deeply collaborative, intellectually demanding, and shaped by rapidly-evolving

❤️‍🔥Are we HARMING the RV while trying to protect the lungs? 🫁 Positive pressure ventilation,especially PEEP, can increase PVR and RV afterload, worsening acute RVF. Are we inadvertently exacerbating RV strain with 'lung-protective' strategies? Go ahead and unload the RV. There

🎙️🌍 "It is untrue that the deaths from measles went away on their own. It took vaccines to get it done." DrDemetre discusses why we need to lean into transparency, call out misinformation, and give people dominion over their medical decisions to stop the next wave of

CVP isn't outdated! It's essential! - Reliable for spotting congestion - Feasible at the bedside - Easy to trend serially The study shows fluid boluses drive up CVP (and venous congestion) especially in non-responders- exactly why we stress: Don't raise it further. Target

Amos Dodi, MD Absolutely. Physiology is not a fashion trend. You just have to use it properly. One of the problems is that the focus on forward flow resulted in much misunderstanding and dismissing of CVP.
