<prompt> In volume-cycled ventilation the inspiratory flow rate is140-160 Lmin110-130 Lmin60-100 Lmin30-50 Lmin  <response>: C i.e. 60-1001min The ventilators serve as energy source only during inspiration replacing the muscles of chest wall diaphragm; expiration is passive driven by the recoil of the lung chest wall In volume cycled ventilation inspiratory flow rate is usually maintained at 60IminQ
