Calculating the partial pressure of oxygen in arterial blood (PaO2) is an essential skill for medical professionals, especially in assessing a patient’s respiratory health. This article will provide a ...

Background: Lower hemoglobin levels have been associated with poor outcomes in patients with out-of-hospital cardiac arrests. Pre-arrest hemoglobin (within 24 hours) and its association with outcomes ...

blood oxygenator What happens when ventilated patients with ARDS receive too much or too little oxygen—and what PaO2 level is optimal? Research to determine a reasonable oxygenation target for ...

In the last decades, the description of the U-shaped association between PaO2 and mortality [1] highlighted the potential dangers of high PaO2 levels (hyperoxaemia) in critically ill patients.

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 1,500 meters. In healthy adults who travel ...
