Squashing an artery to control severe bleeding a.k.a. “Pressure points” is a difficult skill to perform and there is little evidence it helps (and this evidence may be more lore than substance). Our new bleeding control curriculum is Well-aimed direct pressure, Elevation, and as a last resort, apply a Tourniquet. The acronym used to remember this is W-E-T.
As an additional side note, pressure points are also no longer part of the American Red Cross, Pre-Hospital Trauma Life Support, Tactical Combat Casualty curriculum, or the National Registry of EMT Skills Sheets.
