Sanja Jelic, MD, is board-certified in sleep medicine, critical care medicine, pulmonary disease, and internal medicine. A PaO2 test measures oxygen pressure in arterial blood to help guide treatment ...

Pulmonary fibrosis is a rare event occurring in patients with autoimmune Pulmonary Alveolar Proteinosis (aPAP). The accumulation of intra-alveolar material may promote proinflammatory and profibrotic ...

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 ...

Oxygen is a vital element for human life, and lack of it leads to death in just a few minutes. A condition where the respiratory system fails in one or both of its gas exchange functions (oxygenation ...

One of the major roles of the lungs is to facilitate gas exchange between the circulatory system and the external environment. The lungs are composed of branching airways that terminate in respiratory ...

Background: A major contributor to unfavorable outcome after traumatic brain injury (TBI) is secondary brain injury. Low brain tissue oxygen tension (PbtO2) has shown to be an independent predictor of ...

A blood gas test measures oxygen and carbon dioxide levels in the blood. The test can also show blood pH levels and lung function. It is also called an arterial blood gas test or a blood gas analysis.

The alveolar gas equation is used to calculate alveolar oxygen partial pressure as it is not possible to collect gases directly from the alveoli. The equation is helpful in calculating and closely ...
