Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All patients admitted in the intensive care unit at Erasme Hospital Brussels, Belgium will be recruited and if they have an arterial line for at least two days
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 each hour for 5 hours and this will be done for 2 days.
The patient's blood pressure will be measured in parallel with the mobile application and with the reference equipment (arterial line).
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 arterial line (gold standard)
