Agreement and Precision of a Novel Smartphone Application (OPTIBP) For Continuous Blood Pressure Monitoring

2019-10-15 11:11:28 | BioPortfolio


Evaluation of an novel smartphone algorithm designed to estimate blood pressure based on collected optical signals on patients against the reference method, (radial arterial catheter) in patients having major surgeries.


The purpose of the study is to compare the blood pressure values measured by a mobile application used with a smartphone and the values measured by reference method, which is the radial arterial line

Patients scheduled for major surgeries under general anesthesia at the Erasme

Hospital will be recruited and their arterial pressure will be measured with both measurement methods (novel smartphone application and the invasive arterial line).

The placement of an arterial line is standard of care in the institution for patients scheduled for major surgeries. General anesthesia and surgery itself are known to generate significant variations in blood pressure. Since the first minutes of anesthesia, the patient's blood pressure will be measured in parallel with the mobile application and with the reference equipment. Then, during the intervention, measurement will be taken each hour during the duration of the surgery. After the intervention, measurement will be taken once again one hour after arrival in the post-anesthesia care unit or the intensive care unit.

Blood pressure values obtained by the two methods will be compared to confirm the reliability of the data obtained with the mobile application.

Medical and Biotech [MESH] Definitions

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.

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.

The application of scientific knowledge or technology to the field of radiology. The applications center mostly around x-ray or radioisotopes for diagnostic and therapeutic purposes but the technological applications of any radiation or radiologic procedure is within the scope of radiologic technology.

Advanced technology that is costly, requires highly skilled personnel, and is unique in its particular application. Includes innovative, specialized medical/surgical procedures as well as advanced diagnostic and therapeutic equipment.
