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 ...

Case Presentation: A 37-year-old man with no known medical history presented to a pharmacy with agitation and severe chest pain radiating to the back. At 16:00, he experienced a witnessed cardiac ...

The SOFA-2 score included new definitions, new variables, and revised thresholds to categorize the severity of organ dysfunction in critical illness. The updates reflected changes in practice, ...

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

Shunt Fraction refers to the proportion of blood flow that bypasses the normal pulmonary circulation due to a cardiac shunt. This is common in congenital heart defects where abnormal connections ...

Discrepancies between pulse oximetry and arterial oxygen saturation can pose challenges in clinical assessment. Possible underlying causes include poor peripheral perfusion, skin pigmentation, motion ...

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 ...

Exposure to hyperoxia, a high arterial partial pressure of oxygen (PaO2), may be associated with worse outcomes in patients receiving extracorporeal membrane oxygenator (ECMO) support. We examined ...

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 ...
