Oleic acid (OA) of 0.06 ml/kg was injected to induce acute respiratory failure. Tracheostomy was performed in 7 rabbits ventilated under volume-controlled mode in the supine position.Īrterial blood gas analysis, airway pressures, and dead space ventilation were measured at respiratory rate of 20/min as control values. We compared the effect of hybrid ventilation (HV) as a modification of ITPV with PH on the decrease of tidal volume and airway pressures in rabbits with acute respiratory failure. ![]() ![]() Intratracheal pulmonary ventilation (ITPV) was developed to allow a decrease in physiological dead space during mechanical ventilation. High PaCO2 can be permitted to lower airway pressures as in permissive hypercapnia (PH). Abstract BACKGROUNDĪ technique that improves the efficiency of alveolar ventilation should decrease the pressure required and reduce the potential for lung injury during mechanical ventilation. 2Department of Anesthesiology, Samsung Hospital, Seoul, Korea.
