Typically, our anaesthetized patients are monitored with the following: Capnograph (measures expired carbon dioxide and breaths), Apnea alarm (alarms if breathing stops), Pulse Oximetry (
measures Oxygen levels in the blood), Scrolling EKG (measures electrical activity of the heart), Blood Pressures (using a Oscillometric Cardell Blood Pressure unit), Thermometer (keeping the patient warm is critical to success) and of course a dedicated technician monitoring other parameters (like depth of anesthesia, pulse pressures, etc) continuously throughout.
Talking about the features, the renders appear to be showing infrared sensors, which is expected to allow the watch to
measure the oxygen level in the blood.
It will presumably also come with a new infra - red based heart rate scanner that could be used for
measuring oxygen levels in the blood as well.
The leaked renders also indicate Fitbit's new wearable will feature infrared sensors, allowing the smartwatch to
measure oxygen levels in the blood, as well as more accurately determine heart rate and heart rate variability.
This could hint at a pulse oximeter, which actually
measures oxygen levels in the blood, similar to the methods used in a hospital.
Fitbit's next smartwatch might also feature a pulse oximeter for
measuring oxygen levels in the blood.
Not exact matches
Arguably the most convenient and least invasive way of doing that is through functional magnetic resonance imaging, or fMRI — a technique that
measures changes
in blood flow and
blood oxygen levels in the brain, thereby showing which parts of the brain are activated when people perform various tasks.
Researchers
measure the changes
in blood oxygen levels as a marker of brain function.
So Stoléru and other scientists have switched to a faster method, functional MRI (fMRI), which monitors the flow of
blood to active neurons by
measuring levels of
oxygen in the brain.
It does so by
measuring changes
in blood -
oxygen levels in different areas.
The research made use of functional magnetic resonance imaging (fMRI)-- which
measures changes
in the
blood oxygen levels in the brain — and also multivariate analysis when comparing the brain activity of different viewers.
Resting - state functional magnetic resonance imaging allows investigating whole - brain connectivity changes during pharmacological modulation of the
level of consciousness.Low - frequency spontaneous
blood oxygen level - dependent fluctuations were
measured in 19 healthy volunteers during wakefulness, mild sedation, deep sedation with clinical unconsciousness, and subsequent recovery of consciousness.Propofol - induced decrease
in consciousness linearly correlates with decreased corticocortical and thalamocortical connectivity
in frontoparietal networks (i.e., default - and executive - control networks).
The researchers
measured brain activity — the
blood oxygen level — dependent (BOLD) signal —
in brain regions that have previously been associated with food reward processing.
Using a technology called functional Near - InfraRed Spectroscopy (fNIRS), which uses infrared light to track changes
in blood oxygen in different parts of the brain to provide a
measure of what brain regions are becoming more activated (consuming more
oxygen) during certain tasks, the investigation will compare the brain patterns of children with ASD and typical children who have similar imitation scores and eyetracking patterns, to determine whether children with ASD process the same imitation tasks differently from typically developing children, at the
level of their brain activity.
Moreover, the smartwatch has the new SpO2 sensor for
measuring blood oxygen levels and could be used to discover sleep apnea
in the future.
The Ionic smartwatch also has the new SpO2 sensor, which is able to
measure the wearer's
blood oxygen levels in real - time.
Most importantly, it has a new SpO2 sensor which will
measure the user's
blood oxygen levels in real - time and as the company claims, can even
measure sleep apnoea i.e. breathing issues during sleep, which can be highly detrimental to your health.
