Dual-control modes of ventilation are auto-regulated pressure-controlled modes of mechanical ventilation with a user-selected tidal volume target. The ventilator adjusts the pressure limit of the next breath as necessary according to the previous breath's measured exhaled tidal volume.
Modes of mechanical ventilation has only had an established nomenclature since 2008. [1] It is suggested that the modes categorized under the following sections be referred to as their section header instead of their individual name, which is often a brand name instead of the preferred nomenclature.
Pressure-regulated volume control utilizes pressure-limited, volume-targeted, time-cycled breaths that can be either ventilator- or patient-initiated. The peak inspiratory pressure delivered by the ventilator is varied on a breath-to-breath basis to achieve a target tidal volume that is set by the clinician.

Pressure control is used to regulate pressures applied during mechanical ventilation. Air delivered into the patients lungs (breaths) are currently regulated by Volume Control or Pressure Control. In pressure controlled breaths a tidal volume achieved is based on how much volume can be delivered before the pressure control limit is reached. [1]
IMV is a form of ventilation where the ventilator delivers mandatory breaths, but spontaneous breaths are possible between mandatory breaths. Mandatory breaths can be delivered at a set frequency (with spontaneous breaths occurring in between), or can be delivered whenever breath volume per minute falls below a set point. [4] Terms replaced by ...
It is composed of two independent piston pumps and integrated unit allowing for oxygenation of PFC, temperature control, and recovery of evaporated PFC. [13] This liquid ventilator also includes volume and pressure control strategies to optimize the ventilatory cycle: it performs a pressure-regulated volume-controlled ventilation mode. [12]
A pressure-time graphic. Airway pressure release ventilation (APRV) is a pressure control mode of mechanical ventilation that utilizes an inverse ratio ventilation strategy. APRV is an applied continuous positive airway pressure (CPAP) that at a set timed interval releases the applied pressure. Depending on the ventilator manufacturer, it may ...
