A method for controlling a mechanical ventilator that is supplying medical gas to a patient via an endotracheal tube. A pressure is measured from a patient end of an endotracheal tube. The pressure at the patient end of the endotracheal tube is used to create an improved endotracheal tube resistance model such that the medical gas supplied by the mechanical ventilator may be compensated for the resistance of the endotracheal tube thereby providing increased control over the medical gas that is delivered to the patient's lungs. Additionally, if an obstruction in the patient's airway is detected, the location of the obstruction may be targeted such that the proper remedial treatment or procedure is selected by a clinician.

A method is provided for connecting a secondary source of a medical gas to a control panel of a medical gas supply. The control panel is connected in the system fluidly between primary supply sources holding types of medical gas and gas outlets for the delivery of the respective types of medical gas to devices in a medical facility. For each gas type, the control panel houses a respective shut off valve. The shut-off valve may be closed to isolate the upstream source from the downstream components. A fitting is installed in place of an existing pressure gauge in the control panel. The fitting provides ports for at least one gas specific DISS coupler and further components such as a pressure gauge and transducers. The fitting has a configuration such that when installed, the fitting does not interfere with closing the cover to the control panel.
