简要总结
Evaluation of a novel mobile application designed to estimate blood pressure (systolic-diastolic and mean arterial pressure) based on collected optical signals on patient's finger treated in surgical patients in the post-anesthesia care unit
详细描述
The purpose of the study is to compare the blood pressure values measured by a novel mobile phone application ( camera of the smartphone will be obstructed by the patient's right index) and the values measured by reference method used (the oscillometric brachial cuff).
All patients scheduled for noncardiac surgery at Erasme Hospital Brussels, Belgium will be recruited and their pressure will be measured with both mesurement methods. (novel smartphone application versus upper arm cuff oscillometry) at 5 time points (each 20-30 minutes)
The OptiBP Application is a mobile application installed on a mobile phone which is a non-invasive data-logger intended to acquire physiological data from patients. By applying the patient's finger on a smartphone's camera, a movie is generated and transformed into values of diastolic, mean and systolic blood pressure.
Three measures will be taken (spaced by one minute) with both methods after a period of 3 minutes of rest at each time point.
The patient's blood pressure will be measured in parallel with the mobile application and with the reference equipment (the oscillometric brachial cuff).
