Continuous Mandatory Ventilation
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 continuous mandatory ventilation, the ventilator can be triggered either by the patient or mechanically by the ventilator. The ventilator is set to deliver a breath according to parameters selected by the operator. "Controlled mechanical ventilation" is an outdated expansion for "CMV"; "continuous mandatory ventilation" is now accepted standard nomenclature of mechanical ventilation. CMV today can assist or control dynamically, depending on transient presence or absence of spontaneous breathing effort. Thus, today's CMV would have been called ACV (assist-control ventilation) in older nomenclature, and the ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mode Of Mechanical Ventilation
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. The most frequently used forms of volume-limited mechanical ventilation are intermittent mandatory ventilation (IMV) and continuous mandatory ventilation (CMV). There have been substantial changes in the nomenclature of mechanical ventilation over the years, but more recently it has become standardized by many respirology and pulmonology groups. Writing a mode is most proper in all capital letters with a dash between the control variable and the strategy (i.e. PC-IMV, or VC-MMV etc.).

Covidien
Covidien was an Irish-headquartered global health care products company and manufacturer of medical devices and supplies. Covidien became an independent publicly traded company after being spun off from Tyco International in 2007. It was purchased by Medtronic in a transaction that closed in 2015. The now-merged company is headquartered in Ireland, where Covidien was based. History In 2007, Covidien was formed when Tyco International spun off its health care business. In 2012, Covidien acquired Newport Medical Instruments, a small ventilator manufacturer supplier. Newport Medical Instruments had been contracted in 2006 by the U.S. Department of Health and Human Services' Biomedical Advanced Research and Development Authority to design a cheap, portable ventilator. At the time, Newport Medical Instruments had three working prototypes produced, and was on schedule to file for market approval late 2013. Covidien then effectively halted the project, subsequently exiting the cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volume Controlled Intermittent Mandatory Ventilation
Intermittent Mandatory Ventilation (IMV) refers to any mode of mechanical ventilation where a regular series of breaths are scheduled but the ventilator senses patient effort and reschedules mandatory breaths based on the calculated need of the patient. Similar to continuous mandatory ventilation in parameters set for the patients pressures and volumes but distinct in its ability to support a patient by either supporting their own effort or providing support when patient effort is not sensed. IMV is frequently paired with additional strategies to improve weaning from ventilator support or to improve cardiovascular stability in patients who may need full life support. Synchronized intermittent mechanical ventilation (SIMV) Synchronized Intermittent Mechanical Ventilation is a variation of IMV, in which the ventilator breaths are synchronized with patient inspiratory effort. SIMV, with and without pressure support has not been shown to have any advantages over continuous mandatory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Modes Of Mechanical Ventilation By Category
Modes of mechanical ventilation has only had an established nomenclature since 2008. 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. Volume controlled continuous mandatory ventilation * Volume controlled continuous mandatory ventilation (VC-CMV - formerly known as assist control) Volume controlled intermittent mandatory ventilation * Synchronized intermittent mechanical ventilation (SIMV) * Mandatory minute ventilation (MMV) Pressure controlled continuous mandatory ventilation * Pressure controlled continuous mandatory ventilation (PC-CMV) formerly known as simply pressure control ventilation. Pressure controlled intermittent mandatory ventilation * Airway pressure release ventilation (APRV) * Pressure regulated volume control (PRVC) * Proportional assist ventilation (PAV) * Adaptive support ventilation (ASV) C ...

Continuous Spontaneous Ventilation
Continuous spontaneous ventilation is any mode of mechanical ventilation where every breath is spontaneous (i.e., patient triggered and patient cycled). Spontaneous breathing is defined as the movement of gas in and out of the lungs that is produced in response to an individual's respiratory muscles. In a nutshell, spontaneous breathing is natural breathing. while at rest, a typical adult will take an average of 18 breaths per minute. Most people are unaware of their breathing patterns unless something interferes with the efficiency of this process. In extreme cases, mechanical ventilation is used when spontaneous breathing is inadequate or ceases entirely. Dependent modes Some modes of mechanical ventilation require spontaneous ventilation, some of these include: * Bilevel positive airway pressure (BPAP, BiPAP®) * Continuous positive airway pressure (CPAP) * Airway pressure release ventilation Airway pressure release ventilation (APRV) is a pressure control mode of mechanical ...

Nomenclature Of Mechanical Ventilation
Many terms are used in mechanical ventilation, some are specific to brand, model, trademark and mode of mechanical ventilation. There is a standardized nomenclature of mechanical ventilation that is specific about nomenclature related to modes, but not settings and variables. Terms are now split into acronyms of CONTROL VARIABLE + BREATH SEQUENCE + TARGETING SCHEME. As in PC-CMV, Pressure Controlled Continuous Mandatory Ventilation. The term trigger (commonly flow or pressure) denotes the criteria that starts inspiration and cycle denotes the criteria that stops it. The target variable should not be confused with the cycle variable or the control variable. The target variable only sets an upper limit for pressure, volume or flow. Control variable The physical parameter that controls the breath in accordance with the equation of motion Equation of motion Pressure = Elastance*Volume + Resistance*Flow Volume control (VC) Volume controlled ventilation is ventilation where both vo ...
