Key result
The OptiBP smartphone application demonstrated good agreement with invasive arterial monitoring for mean arterial pressure with a bias of 0.9 mmHg, fulfilling AAMI/ISO universal standards.
Why the study?
Measuring blood pressure with a smartphone application could provide more widespread access to hypertension screening and monitoring compared to standard oscillometric methods.
Does the OptiBP optical smartphone application accurately measure blood pressure compared to invasive arterial monitoring in ICU patients?

Does the OptiBP optical smartphone application accurately measure blood pressure compared to invasive arterial monitoring in ICU patients?
Mean Difference: 0.9 (95% CI -13–15)
The OptiBP smartphone application showed good agreement with invasive arterial monitoring for mean and diastolic blood pressure in ICU patients, though systolic pressure measurements did not meet AAMI/ISO standards.
Desebbe et al. (2022) conducted an observational in Intensive Care / Arterial Blood Pressure Monitoring (n=30). OptiBP smartphone application vs. Invasive arterial blood pressure monitoring (radial artery catheter) was evaluated on Agreement (bias) between OptiBP and invasive arterial blood pressure for mean arterial pressure (MAP) (MD 0.9 mmHg, 95% CI -13 to 15). The OptiBP smartphone application demonstrated good agreement with invasive arterial monitoring for mean arterial pressure with a bias of 0.9 mmHg, fulfilling AAMI/ISO universal standards.
