WebMar 1, 2024 · The PaO2/FiO2 ratio, also called the PF ratio, is a useful clinical tool that can be used to determine the lung health of a patient with oxygen therapy. This ratio is often used to diagnose or monitor patients with pulmonary disease, as well as help treat patients in an ICU setting. http://www.ardsnet.org/files/ventilator_protocol_2008-07.pdf

WebThe P/F ratio indicates what the pO2 would be on room air: P/F ratio < 300 is equivalent to a pO2 < 60 mm Hg on room air P/F ratio < 250 is equivalent to a pO2 < 50 mm Hg on room air P/F ratio < 200 is equivalent to a pO2 < 40 mm Hg on room air Example: Suppose the pO2 is 90mmHg on 40% oxygen (F IO2 = .40). The P/F ratio = 90 divided by .40 = 225.
