Blood pressure is measured by an automated oscillometric device or arterial waveform from IntelliVue MX800 Bedside patient monitor (Philips Healthcare, Amsterdam, Netherlands).~Following parameters will be measured by non-invasive electrocardiogram (ECG), photoplethysmograph (PPG), and an accelerometer on the chest and will be used to estimate the biosignal derived blood pressure.~PAT(time between R peak of ECG and beginning of the pulse of PPG)~PEP(time between R peak of ECG and peak of accelerometer signal)~PTT(PAT-PEP)~The algorithm of the biosignal derived blood pressure will be made using the MATLAB 2016b(Mathworks, Natick, MA) program.~The agreement between the non-invasive blood pressure and the biosignal derived blood pressure will be analyzed using Cohen's Kappa or Bland-Altman plot.
The aim of this study is to estimate blood pressure in pediatric patients using a non-invasive electrocardiogram (ECG), photoplethysmograph (PPG), and an accelerometer on the chest.
