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.

Vital signs measure the body’s most essential functions. They include heart rate, body temperature, respiratory rate, blood pressure, and oxygen saturation. Healthcare professionals use vital signs to ...

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.

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 clinically appropriate range for oxygen saturation in preterm infants is unknown. Previous studies have shown that infants had reduced rates of retinopathy of prematurity when lower targets of ...

Babies whose oxygen saturation levels fluctuate widely and repeatedly are often called "swingers" by NICU nurses. Typically, these babies are on CPAP, a mode of respiratory support that is ...
