Patients with COPD who travel to high altitudes have an estimated PaO2 decrease of 0.84 kPa with each 1000 meter of altitude gain. High-altitude travel in patients with chronic obstructive pulmonary ...

Introduction: Post-ischemic re-oxygenation is necessary to minimize ischemic injury, but itself can induce further reperfusion injury through the induction of reactive oxygen species (ROS).

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 ...

Masimo Corporation MASI recently announced the findings of a retrospective study in which researchers assessed the association between Masimo ORi (Oxygen Reserve Index) and the arterial partial ...

The alveolar-arterial gradient, often abbreviated as A-a gradient, is an essential tool in assessing a patient’s lung function and identifying various respiratory disorders. It represents the ...

The P/F ratio, also known as the PaO2/FiO2 ratio, is a valuable tool for evaluating oxygenation status in critically ill patients. It is commonly used to determine the severity of acute respiratory ...

Factors significantly associated with PaO2 levels at high altitudes included the individual’s age, target altitude, and time spent at an altitude of at least 1500 meters. In healthy adults who travel ...

Arterial ulcers and venous ulcers are chronic wounds with different causes and appearances. Arterial ulcers occur due to arterial disease. Venous ulcers develop as a consequence of chronic venous ...

Background: 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 ...
