Abstract
Disclosed herein are methods, systems, and devices for controlling a gas mixture within a mechanical ventilator. According to one embodiment, a computer implemented method includes receiving first peripheral arterial oxygen saturation (SpO) data from a pulse oximeter via a pulse oximeter interface, wherein the pulse oximeter is configured to monitor a patient receiving invasive ventilation; determining a first mode of operation for a ventilator mechanism, wherein the ventilator mechanism is configured to provide at least a portion of the invasive ventilation; determining first partial pressure of oxygen (PaO) data stored in a first lookup table using the first SpOdata, wherein the first lookup table is derived from a sigmoid shaped oxyhemoglobin dissociation curve; determining first fraction of inspired oxygen in air (FiO) data for setting a mixture in a gas blender in the ventilator mechanism based on the first PaOdata and a variable offset; and providing the FiOdata to the ventilator mechanism.
