According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low, and indicate the need for supplemental oxygen. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, inc...

For example, an incredible development project by the University of South Australia is for drones to eventually be able to survey populations for disease by reading the blood oxygen levels of humans from the air. They’ll also be able to scan for other vital signs, like coughing and a high...
blood oxygen levels. The ability of pulse oximetry to offer an early warning for various lung-related issues is why some healthcare professionals suggest that COVID-19 patients monitor their oxygen saturation periodically. In general, clinicians often assess patients’ oxygen saturation levels during ...
Blood sugar, or glucose, is the main source of fuel for our bodies. It powers up our internal organs, muscles and nervous system. Keeping your blood sugar in check is essential to our physical health, wellbeing and energy levels. But what is considered a normal blood glucose level? And ...
What is a stroke?A stroke happens when blood flow to part of the brain is stopped. This can cause serious brain damage from a lack of oxygen. A stroke caused by a blood clot is called an ischemic stroke. A stroke caused by a burst or torn blood vessel is called an intracerebral ...
Anything above the normal range (0 and 0.4 ng/mL) is considered to be an elevated troponin level in the blood. However, the higher the level is, the more likely it is that a heart attack occurred. What level indicates a heart attack? A measurement close to 0.4 may not necessarily mean...
The leaked blood may also collect in one area. This is called a hematoma. A hematoma can create pressure that keeps oxygen from flowing to the brain. Brain damage may happen within a few minutes if the brain cannot get enough oxygen. An ICH is a medical emergency that needs immediate ...
The nature of the delivery of O2 to tissues and the mechanisms by which O2 is consumed necessarily result in very different levels of O2 within the volume of each voxel of a measurement. Better spatial resolution cannot fully resolve the problem because the variations include O2 gradients within...
What is an ischemic stroke?An ischemic stroke occurs when blood flow to part of your brain is blocked. The block is usually caused by a blood clot that gets stuck in a narrow blood vessel. When oxygen cannot get to an area of the brain, tissue in that area may get damaged. The ...
