The PF ratio is a useful and quick tool that we have at our disposal to quantify the degree of respiratory failure that our patient has. Having this easy measurement also allows us to trend our patients respiratory failure to determine if they are stable, improving, or deteriorating. It's a simple calculation of just dividing the PaO2 from an ABG by the FiO2 expressed as a decimal. We can also use this PF ratio to then see test how our patient would respond to differing levels of oxygen delivery.

NOTE: Its dissociation not disassociation curve 🤦🏻‍♂️
