![]() In the other 8 patients, no BP could be measured due to inadequate signals. ResultsĪmong the 30 recruited patients, 22 patients had adequate OptiBP™ values and were thus analyzed. The performance of the smartphone application was investigated using the Association for the Advancement of Medical Instrumentation (AAMI) and the International Organization for Standardization (ISO) definitions, which require the bias ± SD between two technologies to be below 5 ± 8 mmHg. Bland–Altman and error grid analyses were used for agreement analysis between both approaches. ![]() ![]() We simultaneously measured three BP values every hour for five consecutive hours on two consecutive days using both the smartphone and arterial methods. In this observational study in intensive care unit patients, we compared blood pressure values obtained using a new optical smartphone application (OptiBP™ test method) with arterial BP values obtained using a radial artery catheter (reference method) in order to help validate the technology. While it is currently diagnosed and monitored non-invasively using the oscillometric method, having the ability to measure blood pressure (BP) using a smartphone application could provide more widespread access to hypertension screening and monitoring. ![]() Arterial hypertension is a worldwide public health problem. ![]()
