Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation.The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
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.
There are many modes of mechanical ventilation. [1] In medicine, mechanical ventilation is a method to mechanically assist or replace spontaneous breathing. A breath by breath trigger, limit, cycling (TLC) classification of the common modes of ventilation. (V = ventilator; P = patient) [2]
Mechanical ventilation or assisted ventilation is the medical term for using a ventilator machine to fully or partially provide artificial ventilation.Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide.
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.
Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
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.
Mandatory minute ventilation (MMV) (also called minimum minute ventilation) is a mode of mechanical ventilation which requires the operator to determine what the appropriate minute ventilation for the patient should be and the ventilator then monitors the patient's ability to generate this volume. If the calculation suggests the volume target ...
