What does a PaO2 level of 80-100 mmHg indicate in an ABG analysis?

A PaO2 level of 80-100 mmHg indicates normal oxygenation in an arterial blood gas (ABG) analysis. This range suggests that the patient is receiving adequate oxygen and that the lungs are functioning properly in terms of gas exchange. In healthy individuals, this level reflects sufficient oxygen saturation, which is crucial for maintaining normal cellular function and metabolic processes in the body.

The significance of maintaining PaO2 within this range is fundamental to patient assessment and management. When levels fall below this range, it can indicate hypoxemia, while levels significantly above might suggest other pathological conditions but are not represented in this answer choice. Thus, understanding these ranges is crucial for flight paramedics, who are often required to make rapid assessments of a patient's respiratory status in emergency situations.
