For a little non-COVID #FOAMed, which we still need…
Here’s one that always gets me, that I always try to make sure the residents always understand before they leave our rotation!
I’m pretty sure if you have been fortunate enough to not come across someone doing this, you will – when you do, find a tactful way to share the knowledge!
Oh and don’t forget that H&R Reloaded is on!
cheers

Loved it ! Great refresher/reminder for trainees and staff. Hemoglobin is a concentration (mass in a given volume) -assess your perceived volume lost (or remaining volume), and don’t forget your diluents.
