Blood oxygen levels refer to the amount of oxygen circulating in the blood. Normal blood oxygen levels fall between 75 and 100 millimeters of mercury (mm Hg) on arterial blood gas (ABG) test results.

Supplemental oxygen in patients with confirmed myocardial infarction has no clinical benefit irrespective of oxygen saturation levels at baseline, a new analysis of the Determination of the Role of ...

Scientists have revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound's effect on haemoglobin can improve oxygen's transfer from the lungs to bodily ...

Supplemental oxygen therapy in patients with suspected or confirmed myocardial infarction and normal blood oxygen saturation levels is not associated with any clinical benefit, a new meta-analysis ...

Previous studies have suggested that the incidence of retinopathy is lower in preterm infants with exposure to reduced levels of oxygenation than in those exposed to higher levels of oxygenation.

Some persons have compared the SUPPORT study with studies in the 1950s in which oxygen delivery was restricted without measurement of oxygenation status; this restriction probably created hypoxia and ...

To determine whether there are differences in retinal vascular oxygen saturation measurements, estimated using a hyperspectral fundus camera, between normal eyes and treated eyes of subjects with ...

Proof-of-principle study: Researchers have demonstrated that smartphones are capable of detecting blood-oxygen saturation levels down to 70%. Subjects place their finger over the camera and flash of a ...

The Apple Watch Series 6 has a sensor built in that can measure the oxygen level in the blood. This ability could have a real benefit in judging health and reacting to the first signs of conditions ...
