Summary
A developer recounts his experience with a 24-hour blood pressure monitoring study after receiving a concerning reading at a pharmacy. He describes reverse-engineering the proprietary protocol of the medical device to access his own data, documenting the technical process of analyzing the device's communication protocol, decoding the data format, and creating a Python script to read measurements. The article combines personal health experience with technical problem-solving, highlighting issues with medical device data accessibility and patient rights to their own health information.
Key quotes
· 5 pulledYesterday after receiving my yearly flu vaccine at the pharmacy I was offered a blood pressure test, which reported a reading that made the young pharmacist who had just given me my vaccine a bit worried.
Can I read the measurements? I asked, as it was being strapped to my arm.
The device was a proprietary medical device, and the data was stored in a format that was not accessible to me.
I decided to reverse-engineer the protocol to read my own data.
This is a story about how I reverse-engineered the protocol for my blood pressure monitor in 24 hours.
