No Way!!
With a toolkit of simple monitoring devices so individuals can keep track of their own vitals; what would the medico-techno-pharma-complex do to keep them in thrall?
I’d buy stock in this tomorrow.
Wow! That Liz Holmes is just incredible!
Heart rate and oxygen levels, I get. You can buy a thousand different versions of a finger blood oxygen/heart rate monitor on Amazon today.
Blood pressure based on a peripheral like a finger is iffy at best. And there is nothing in a finger that will indicate respiration rate beyond blood oxygen levels.
I call semi-BS on this ‘breakthrough’ 3D printed oxygen meter.
An early test of the device with 26 study participants has provided an accuracy rate of about 90% for systolic blood pressure, and a 63% accuracy rate for diastolic blood pressure. Byfield said the accuracy rate differs between systolic and diastolic because diastolic, which is a person’s minimum blood pressure, can change significantly depending on a person’s age, and can also be controlled by various factors, including age, artery stiffness, overall health and body weight.
Byfield and his colleagues also acknowledge there are some issues with making PPG sensors work to obtain these measurements.
“Typically, there are a few problems with PPG sensors,” Byfield said. “One is called artifact motion—if you move a PPG sensor while it’s reading, it can affect the waves that are being recorded. On top of that, we found that differences in pressure can alter the waves, but with a finger clip design, a spring provides constant pressure. Another reason this method hasn’t been explored much before is typically these finger clips only have one sensor, but we have two sensors in our device.”
“Custom finger clip offers a new way to measure blood pressure, other vitals”
Looks as though Elizabeth Holmes was in a hurry to get back to work.
Come to think of it, the inductive pickup on my Timing Light has the same type of clamp. Can’t hurt to see if it works!
