Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evaluation of a novel smartphone application designed to estimate blood pressure (systolic-diastolic and mean arterial pressure) and heart rate based on collected optical signals on patient's finger treated in the emergency department against the reference method (the oscillometric brachial cuff )

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of the study is to compare the blood pressure values measured by a novel smartphone 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 admitted to the emergency department at Erasme Hospital Brussels, Belgium during 5 consecutive weeks will be recruited and their pressure will be measured with both mesurement methods. (novel smartphone application versus upper arm cuff oscillometry).

The OptiBP Application is a mobile application installed on a smartphone 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 (+ heart rate), as well as patient's heart rate.

After having compared that the blood pressure in both arms are similar ( maximum of 10 mmHg of blood pressure difference between both arms), three measures will be taken (spaced by one minute) with both methods after a period of 3 minutes of rest (supine position).

The patient's blood pressure will be measured in parallel with the mobile application and with the reference equipment (the oscillometric brachial cuff).

Then, the values obtained by the two methods will be compared to confirm the reliability of the data obtained with the novel mobile application.

The goal is therefore to compare blood pressure values as obtained by the analysis of the data recorded by the OptiBP Mobile Application, against simultaneous measurements provided by the oscillometric brachial cuff
