Medical science never stands still. Researchers across the globe are continually striving to improve technology and the way we treat critically ill patients. Every now and then, one publication amongst the many makes us reconsider and maybe change direction. The article below is the first in our new collection, where we take these watershed papers and get straight to the point ‑ by stripping them back to the key facts and findings and presenting them in a standardized, easy‑to‑digest format. We hope you enjoy it and would love to hear your feedback or comments.
