Sphygmomanornetry the pediatric patient

The indirect measurement of blood pressure in the pediatric population is often difficult or impossible to perform and when values are obtained, they are often unreliable or inaccurate. An accurate measurement of arterial systolic pressure in the upper extremity is obtainable with a properly designed and sized occluding cuff and an ultrasonic device to detect the first Korotkoff sound. For the detection of the first Korotkoff sound ultrasonic Doppler devices are superior to the stethoscope. When wider occluding cuffs than usual are applied to the upper extremity, the error of measurement is minimized. A method for accurately measuring end diastolic pressure has yet to be described despite assertions to the contrary.
