How do we measure oxygenation?
How do we measure oxygenation? One important way is by looking at PaO2, which stands for the partial pressure of oxygen dissolved in arterial blood. PaO2 is measured on an arterial blood gas (ABG) and helps us understand how well oxygen is moving from the lungs into the blood. Normal PaO2 is about 80 to 100 mmHg at sea level. For reference ...

SpO2 vs. PaO2 🩸🫁 🫁Oxygen measurements are not all the same! It’s important to know the differences between readings and what these are truly measuring (percentage, pressure, etc.) ⭐SpO2 (oxygen saturation) → the percentage of hemoglobin bound to oxygen → Most commonly measured with a pulse oximeter, or “pulse ox”, which is a small device which clips onto the patient’s finger. It’s a quick reading, and gives us an idea of the patient’s oxygenation status. → Take Note! Patients with COPD may ha
