WebPaO2 is an important parameter used in medical settings to assess the oxygenation status of a patient's blood. A normal PaO2 range is typically between 75-100 mmHg. Values below this range may indicate hypoxemia, a condition where there is insufficient oxygen supply to the body tissues. What is Fio2 FiO2 stands for Fraction of Inspired Oxygen.
