发明名称 Automatic determination of passive elastic and resistive properties of the respiratory system during assisted mechanical ventilation
摘要 Passive elastic and resistance values for a particular patient are estimated during proportional assist ventilation and other forms of assisted ventilation to permit reliable adjustment for volume-related and flow-related assist gains to meet continuously varying patient muscle pressure. Independent but simultaneous procedures are effected to determine the respective values. The pressure-volume relationship is determined by a modification of the inspiratory hold technique while the pressure-flow relationship is determined by deliberately introducing brief perturbations in pressure, flow and volume and observing the effects obtained.
