Blood Pressure CuffTaking an accurate blood pressure was one of the first things we all learned in EMT or First Responder class, but it can be very easy to get in the habit of using poor technique when wrapping the cuff around a patient’s arm. Here are a few quick reminders to improve your blood pressure assessment skills.

• Expose the patient’s arm. Bulky clothing significantly reduces the accuracy of the cuff.

• Be careful rolling the sleeve up. If it is too tight it may inadvertently restrict blood flow to the arm.

• Use the right size cuff. A cuff that is too large will give readings that are lower than reality. A cuff that is too small will give readings that are higher than the actual blood pressure.

• Use the bell on your stethoscope if it has one. The bell picks up low tones better than the diaphragm.

• Make sure your manual BP cuff is calibrated. After time, use and abuse they can get “out of zero.” Check the instructions for your model for calibration instructions, but most have a little box or circle at the bottom of the sphygmomanometer gauge where the needle should rest when the cuff is completely deflated.

• Document the patient’s position when you took their BP and the arm on which you took it.
