Assess the Accuracy of Transtek TMB-1591-A-002 Blood Pressure Monitor in Conformance With the ANSI/AAMI ISO 81060-2 Standard

1. Introduction:

Automated blood pressure cuff measurement is the standard of care in numerous medical settings today. This study was designed to assess the accuracy of a previously cleared automated blood pressure cuff system using the same arm sequential dual observer auscultation method. The study was conducted in accordance to ANSI/AAMI/ISO 81060-2:2013 Non-invasive sphygmomanometers - Part 2: Clinical investigation of automated measurement type, the Code of Federal Regulations requirements for Non-Significant Risk Device Investigations and as appropriate ISO 14155: Clinical investigation of medical devices for human subjects - Good clinical practice. 2. Purpose of Clinical Investigation:

The purpose of this study is to provide supporting documentation for non-invasive blood pressure measurement Accuracy claims for the TMB-1591-A-002 Blood Pressure System with Reusable Cuffs on the intended adult and pediatric population. 3. Clinical Investigation Population:

Following Salus Independent Review Board (IRB) approval, a total of 90 subjects were screened and enrolled into the study and data was collected. Two subjects were withdrawn from the study and the data was not used in the data analysis. These subjects were removed due to difficulty in hearing the reference blood pressure range (systolic and/or diastolic) and the other was removed due an unstable systolic range. A total of 88 healthy subjects, (53 adult / adolescent and 35 pediatric) ages 3-75yr, arm circumference 15-49.5 cm, systolic blood pressures ranges 79-176.5 and diastolic blood pressure ranges of 49-116 were included in the study for analysis. The study was conducted May 30 - June 16, 2017 to perform an accuracy validation on TMB-1591-A-002 Blood Pressure System with FlexiPortTM Reusable Cuffs. 4. Method:

The requirements for the study were to include a minimum of 85 subjects with a minimum of 35 pediatric subjects 3-12 years of age and the remainder over 12 years of age, with at least 30% being male and 30% being female, and an arm circumference range of 15-55cm where at least six subjects were evaluated in each of the seven cuffs. For the data collection, at least 90% of the subjects needed to contribute 3 paired observations allowing the remaining 10% to be 2 paired observations. A minimum of 255 valid paired observations were needed for the analysis.
