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.

The invention provides a special gas supply and distribution device and relates to the transportation field of gas with high purity. The special gas supply and distribution device comprises a gas source supplying device (1), valves (21-24), pressure sensors (31, 32), a front segment filter (41), a back segment filter (42), an excess-flow detector (5), a testing port (6), a pneumatic corner valve (7), a vacuum generator (8), a gas cylinder (9) and an untight valve (10). With the specific gas transportation structure adopted, high purity and high cleanliness during the gas transportation are ensured, therefore, the device is safe and reliable. Digital signals are transported to PLC by adopting an RJ45 network wire to substitute analog signals which are used by a traditional control system in the past. The special gas supply and distribution device has the advantages of fast transportation speed, large volume, convenient integration and low cost.
