Ultrasound-PV-Card-smAs emergency medicine providers become more proficient in using bedside ultrasonography as a diagnostic tool, it can be difficult to remember all of the normal cutoff values. Is it 3 or 5 mm as the cutoff? Thanks to the team at UCSF (Dr. Maria Beylin, Dr. Scott Fischette, and Dr. Nate Teismann) for creating a succinct PV card listing the key numbers to remember. You can download this PV card into your mobile device as a reference guide, or you can even print and attach to each of your ultrasound machines!
