This device allows for protective mechanical ventilation by the reduction of tidal volumes and decreased end expiratory pressures.
From the clinical editor by Price, Paula / Dynamics
To understand the shortcomings of PSV, two things must be kept in mind: 1) The actual pressure that inflates the lung is the sum of the airway and pleural pressures (transpulmonary pressure, PTP); and 2) The PTP needed depends not only on tidal volume and flow, but also on the mechanics of the respiratory system.
The shortcomings of pressure support by Marini, John / FOCUS: Journal for Respiratory Care & Sleep Medicine
The initial increase in ventilation is due first to an increase in tidal volume and then to an increase in respiratory rate.
