🫁 What happened to ARDS? 20 years ago ARDS was everywhere. Now we rarely see it. We didn't cure it. We just stopped causing it. Here’s how IV fluids quietly created (and solved) an epidemic of iatrogenic lung injury 🧵

The wait is over..it’s the start of something new! 👏 The Intensive Care Society 💙 ICS Cast begins … and where better to kick it all off than at #SOA25! 🔊 #FOAMed #POCUS #FOAMcc #Medx #Meded What’s in store??🤔

🧵1/ Hypovolaemia is the most overdiagnosed concept in medicine. We say it reflexively — especially in sepsis. But here’s the uncomfortable truth: We can’t measure blood volume. We infer it. Often wrongly. Let’s unpack why that matters. 👇 #MedTwitter #FOAMed

1/ Most people think the heart drives circulation. But what if that’s backwards? Anderson’s model flips the whole idea of cardiac output on its head — and it changes how you think about fluid, flow, and failure. 🧵👇 #physiology #FOAMed #MedTwitter #criticalCare #cardiacOutput

At Intensive Care Society 💙 #SOA25? Love #POCUS or want to learn more? Come and hear from Jennie Stephens how we got to a world-class accreditation programme with #FUSIC in the UK, and enjoy a competitive showcase of great examples of when #POCUS saved the day.

Some of the Turning the Tide team at Intensive Care Society 💙 #SOA2025 delivering a tour de force of macro and micro circulation physiology, but also a reminder of how not to cause unintentional harm to critically unwell patients by not carefully managing fluid therapy.

Do you struggle with the Ultrasound Guided Ankle block? Think it’s tricky and not worth the hassle? In this video tutorial - I try to demystify it, as if we were at an ultrasound scanning workshop. No bells & whistles (apart from a lovely machine!) 👇🏼 youtu.be/Bl0_x-hn3yA?si…

Great to be able to contribute to a session on oedema, venous congestion and rational fluid prescribing at #SOA25 with 2 such passionate and talented presenters Andy Breen and Ross Prager. I’ve done lots of talks but hard not to feel nervous in such a big auditorium! Remember -

💉 “Give a fluid challenge — see if we can get the norad down.” We’ve all heard it. Boluses are often given just to reduce vasopressor doses. Why? • Fear that pressors are harmful • Pressure to keep patients off ICU But topping up to drop the norad might not be the best move…

💧Fluid creep accounts for more fluid than resuscitation in ICU. But nobody prescribes it — and most don’t even notice it. The truth? 🧨 Most ICU patients don’t need routine maintenance fluids. Here’s what’s really going on 👇🧵
