Evaluation of a novel smartphone application designed to estimate blood pressure (systolic-diastolic and mean arterial pressure) based on collected optical signals on patient's finger treated in the emergency department against the reference method (the oscillometric brachial cuff )
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 one consecutive week 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, as well as patient's heart rate.
Three measures will be taken (spaced a minute) with both methods 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

Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.
Phenomenon where increased BLOOD PRESSURE readings taken in non-clinical settings (e.g., HOME BLOOD PRESSURE MONITORING) do not replicate in clinical settings.
The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.
The application of technology to the solution of medical problems.
