Abstract
A system for assessing lung function in a patient is enclosed. The oxygen delivery system in the system (e.g., a ventilator or portable standalone system) preferably includes an oximeter sensor for receiving SpO2 from a patient. The assessing lung function in a patient includes an FiO2 adjust algorithm operable in logic circuitry in the ventilator that can control an oxygen fraction FiO2 provided to the patient in a closed loop fashion. In a preferred example, the algorithm controls FiO2 using the SpO2, but also displays a ratio of SpO2-to FiO2 (S/F) as a function of time. One or more S/F ratio threshold may be used to allow the clinician and/or the algorithm to understand a degree of lung injury, and to allow the algorithm to adjust FiO2 appropriately. Preferably, the algorithm keeps SpO2 to a range of 88-95%.
