I'm currently exploring the possibility of developing a cuffless and non-invasive blood pressure monitoring device using Arduino. My goal is to design a system that can continuously measure blood pressure without the need for a traditional cuff, which can be uncomfortable for some patients and disruptive in long-term monitoring scenarios.
I've read about various methods, including the use of photoplethysmography (PPG), arterial tonometry and other sensor-based techniques that can detect blood flow and pressure changes indirectly. However, integrating these methods into a reliable Arduino-based system poses some challenges, particularly in signal processing and achieving accurate measurements.
I would really appreciate it if anyone here could share their experiences, tutorials, or resources on how to implement such technologies with Arduino. Specifically, I'm looking for guidance on sensor selection and assemble
If you've worked on similar projects or have links to tutorials that might help, please share them. Your insights will be invaluable to making this project a success!
we want to recreate this, but don't know which sensors we need exactly. We think that we need to use photoplethysmography and a pneumatic system. Photoplethysmography - MAX30100 and we don't know about the pneumatic system. Actually, we are researching and haven't tried it yet.
Hi, @adwk12
In the document linked in post #5.
This line;
In the last case,
the fnger BP is monitored by a photoplethysmography device coupled to an inflatable cuff controlled by a servo valve to keep constant the diameter of the artery.
Still uses a cuff.
In fact the cuff would be inflated constantly to keep, " constant the diameter of the artery", so I see no advantage of your proposal.
Can you please tell us your electronics, programming, arduino, hardware experience?
