However, this terminology is so widely employed that I will use it throughout this series of posts on high risk medical procedures. The term “AGMP” is really used to identify clinical scenarios […]
I am working hard on updating all the evidence around “aerosol generating medical procedures” or AGMPs, but I think this is a failed and probably harmful paradigm. I will still complete my write-ups because the terminology is so widely used, but I think we would all be better off if […]
In early April, I wrote a long post covering all the science I could find about aerosols and droplets. The basic summary was that this is an area of medicine with lots of misconceptions, poor assumptions, and incomplete science. There was good evidence that previous coronaviruses were spread by aerosols. […]
