Understanding Oxygen Saturation Levels in Medical Practice

P/F Ratio | PaO2/FiO2 Ratio

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

How does Pulse oximeter work? Pulse oximetry is a non-invasive and painless test that measures your oxygen saturation level, or the oxygen levels in your blood. During a pulse oximetry reading, a small clamp-like device is placed on a finger, earlobe, or toe. Small beams of light pass through the blood in the finger, measuring the amount of oxygen. It does this by measuring changes of light absorption in oxygenated or deoxygenated blood. This is a painless process. The pulse oximeter will thus b
