Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

We read the recently published article, ‘How accurate is EUS-guided direct portal vein pressure measurement? A comparison with intraoperative measurements’ with great interest. In this article,1 Singh ...

Abstract: Objective: Oscillometric finger pressing is a potential method for smartphone-based blood pressure (BP) monitoring. A photoplethysmography (PPG)-force sensor unit measures the slowly ...

Ōura Health, maker of the sleek ring that tracks sleep, stress, and fitness, has formally petitioned the FDA for clearance to continuously monitor blood pressure through its optical sensors. If ...

Missing blood pressure (BP) records within 2 years prior to diagnosis were associated with substantially higher risks for major adverse cardiovascular events (MACEs) and all-cause mortality in older ...

Introduction: Blood pressure (BP) is a complex physiological marker. Cuffless devices, often based on photoplethysmography (PPG), enable frequent or continuous BP monitoring without arterial occlusion ...

Why this is important: Okay, so the stress feature is really cool. It’s not just going to tell you you’re stressed right now. Instead, it looks at the big picture. What’s next: To make sure the blood ...

Uncover how mixed-signal ICs are transforming medical wearables with smaller and more power-efficient sensor integration, enabling real-time health monitoring. Healthcare technology is at the center ...
