Correlation of Wrist and Arm Blood Pressure Measurements

This study will compare an automated wrist blood pressure device (Omron 3 Series Wrist Blood Pressure Monitor) with both an automated arm blood pressure device (Welch Allyn ProBP 3400 series) and a manual aneroid blood pressure device. The goal is to assess correlation of wrist blood pressure readings to manual and automated arm readings, and to determine the utility of wrist monitors in both clinic and home ambulatory blood pressure monitoring in the pediatric population.

Inclusion Criteria

• Patients of Tufts Pediatric Nephrology Clinic during the study period
• Age 7 years to 21 years
• Wrist circumference between 13.5 cm and 21.5 cm
  

Exclusion Criteria

• Abrasions or open wounds on arm or wrist
• Neurologic condition that causes asymmetric muscle bulk, increased muscle tone, or contractures of the arm or wrist
• Non-English speaking

Study Requirements

This study will require the patient to sit for 7 total blood pressure readings. The study will only include the initial clinic visit, with no research follow up visits required. Estimated time required for the 7 blood pressure readings is 15 minutes. There is no labwork or imaging required as a part of this study.
