Abstract: This paper proposes a novel mathematical model that quantitatively defines the relationships between the arterial oxygen saturation (SaO2), the arterial partial pressure of oxygen (PaO2) and ...

A study by Norwegian & Italian Universities/Institutes found that common pulse oximeters are generally accurate for oxygen levels between 85-100% However, their ...

Chronic obstructive pulmonary disease (COPD) is globally the third leading cause of death, causing 3.23 million deaths in 2019. Most feasible way to measure oxygen saturation is by pulse oximetry ...

The respiratory system provides oxygen to and removes carbon dioxide from the body; however, the inability to perform either or both of these tasks results in respiratory failure. Type 1 respiratory ...

Near-infrared spectroscopy (NIRS) measurement of regional cerebral tissue oxygen saturation (rcStO2) has become a topic of high interest in neonatology. Multiple studies have demonstrated that rcStO2 ...

Blood gas analysis allows the assessment of patients’ oxygenation, ventilation, acid-base balance and metabolic status. This article, the sixth in a series on essential critical care skills, outlines ...
