Sky Labs presented its ring-type blood pressure monitor, CART BP pro, at the Digital Biomarkers in Clinical Trials Summit in Basel, Switzerland. The company is pitching the device as a data platform for drug clinical trials, aiming to replace conventional cuff-based monitors that often disrupt sleep and increase dropout rates.
Conventional 24-hour ambulatory blood pressure monitors use an arm cuff that inflates repeatedly. A 2011 study by Viera et al. found that 70.2% of users experienced sleep disruption. Among participants with low tolerability, the failure rate for collecting adequate 24-hour data reached 50.0% on repeated measurements. Those dropout rates raise costs and stretch clinical timelines.
CART BP pro is a cuffless ring worn on the finger. It collects blood pressure data during daily activities and sleep without repeated arm constriction. The company says this reduces the measurement burden on subjects and helps secure stable, long-term vital signs data, including heart rate.
