Document Type and Number:
Japanese Patent JP2003525647
Kind Code:
A
Abstract:
A ventilation system is controlled by detecting the resistance and elastance of the patient's respiratory system and adjusting the flow supplied by the ventilator accordingly. In one embodiment, the resistance is detected by controlling the ventilator to superimpose at least one forced single oscillation on the flow and observing the reaction of the respiratory system. In another embodiment, the elastance is detected by controlling the ventilator to supply a pressure which has the effect of temporarily occluding the respiratory system, waiting until the respiratory system has reached equilibrium, and observing the resulting state of the respiratory system. The detection techniques of these two embodiments can be used together.
