BP should be measured in the right arm using standard practices, similar to the method used for adults (see Figure 2 in Chapter 1). The AAP 2017 Clinical Practice guidelines also provide considerable detail on correct BP measurement methods.1 When possible, in the clinic, the use of auscultatory BP is preferred, as normative BP data in children are obtained using this technique, and there are signi cant differences between values obtained by oscillometric and auscultatory measurements, with oscillometric measures being slightly www.kidney-international.org chapter 5 higher on average.1,3,362 Regardless, RCT data targeting either oscillometric or auscultatory BP measurements obtained in the clinic setting in children are lacking.363 For practical purposes, the initial BP measurement in a clinic setting may be oscillometric using a calibrated machine that has been validated for use in the pediatric population.1,3 However, conversion from oscillometric to ascultatory measurement on an individual basis is dif cult. In individuals at particularly high risk for elevated BP (e.g., those with glomerular dis- readings should then be con rmed by auscultation. Use of HBPM in children requires further study and has not been endorsed for the diagnosis of hypertension by the AAP Clinical Practice Guideline. When performed, elec- tronic upper-arm cuff monitors, which have been clinically validated in children, should be used with appropriate cuff size. Validation status for oscillometric BP devices in the pediatric age group can be checked at stridebp.org. HBPM should be performed for 7 days (not less than 3), with duplicate morning and evening measurements after 5 mi- nutes of sitting at rest and 1 minute between measurements (total of at least 12 readings per week).
