Kristine Tuttle on Instagram: "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.
