Our weekly letter
One clinical question, properly explained, every week in six minutes.
Why do we give adrenaline during cardiac arrest? Which rhythms should we shock? Why do we prescribe fluids the way we do?
Each six-minute letter traces a familiar part of clinical practice through its physiology, original evidence and medical history — so you understand not just what we do, but why.
