    <p>The inspiratory pump (Insp. Pump) delivers the tidal inspiratory volume of perflubron into the lungs. The expiratory pump (Exp. Pump) removes the tidal expiratory volume of perflubron from the lungs. The pressure sensor located at the mouth (P. sensor mouth) is used to limit the driving inspiratory and expiratory pressures and to monitor the pause pressure. P. sensor airway was previously used in the past to characterize the pressure drop although is no longer used.</p

    <p>The pressure generated by the ventilator, while fluid is instilled into the lungs, is identified by the letter "a" on the upper panel. As the movement of PFC stops ("b" at end inspiration and "c" at end expiration), pressure oscillates around a value that can be extrapolated [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191885#pone.0191885.ref018" target="_blank">18</a>]. These values, called pause pressures, are the alveolar pressures at end inspiration and end expiration.</p
