To evaluate partial pressure of oxygen in arterial blood/fractional percentage of inspired oxygen (PaO2 /FiO2 ) and SaO2 /FiO2 ratios (where SaO2 is percentage of oxyhemoglobin saturation in arterial ...

Introduction Targeted oxygenation protocols in mechanically ventilated patients are critical in avoiding the deleterious effects of hypoxaemia and hyperoxaemia. Peripheral oxygen saturation (SpO2) is ...

Laghi, F., Shaikh, H. & Caccani, N. Basing intubation of acutely hypoxemic patients on physiologic principles. Ann. Intensive Care 14, 86 (2024). https://doi.org/10. ...

The article does not also mention the phase delay to the "real" change CaO2, SpO2 differs in points of actual change depending on the point of measurement, Ear probes are more in phase than Finger ...

It is uncertain whether skin pigmentation affects pulse oximeter accuracy at low HbO2 saturation. The accuracy of finger pulse oximeters during stable, plateau levels of arterial oxygen saturation ...

Problem While SpO2 is a good approximation of SaO2 when saturation is above 90%, this is not necessarily the case at lower saturations (see for example Lebecque, 1991). It is also treated separately ...

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 ...

Introduction Clinicians often obtain peripheral saturation (SpO2) readings by placing a finger probe sensor on the patient’s earlobe when a reading cannot be obtained from the finger. The accuracy of ...

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 ...

Aim Accurate measurement of Hb saturation is essential in the care of children with sickle cell disease (SCD). The gold standard of Hb saturation measurement is by ABG with co-oximetry.
