There is a standardized nomenclature of mechanical ventilation that is specific about nomenclature related to modes, but not settings and variables. [2] Terms are now split into acronyms of CONTROL VARIABLE + BREATH SEQUENCE + TARGETING SCHEME. As in PC-CMV, Pressure Controlled Continuous Mandatory Ventilation.
Ventilators may also be equipped with monitoring and alarm systems for patient-related parameters (e.g., pressure, volume, and flow) and ventilator function (e.g., air leakage, power failure, mechanical failure), backup batteries, oxygen tanks, and remote control. The pneumatic system is nowadays often replaced by a computer-controlled turbopump.
volume control ventilation A preset tidal volume is delivered at a set rate by mechanical ventilator. Peak pressure can vary from breath to breath depending on lung compliance, and may be limited by an alarm setting. [58] volume support ventilation Ventilator support of patient initiated breathing based on a set volume delivery. [58]
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]

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.
Continuous mandatory ventilation (CMV) is a mode of mechanical ventilation in which breaths are delivered based on set variables. Still used in the operating room, in previous nomenclature, CMV referred to "controlled mechanical ventilation" ("control mode ventilation"), a mode of ventilation characterized by a ventilator that makes no effort to sense patient breathing effort.
In assist control, one of those two variables will be controlled by the ventilator, either pressure or volume. Typically, in AC/CMV, it is volume. In AC/CMV, the ventilator will deliver a set volume whenever the patient triggers a breath. In contrast, pressure support delivers a set pressure for every triggered breath, rather than a set volume.
