Mandatory minute ventilation

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 will not be met, supplemental breaths are delivered at the targeted volume to achieve the desired minute ventilation.

Application

Mandatory minute ventilation is a volume control mode of ventilation and a derivative of intermittent mandatory ventilation.[1] Mandatory minute ventilation allows spontaneous breathing with automatic adjustments of mandatory ventilation to meet the patient’s preset minimum minute volume requirement. If the patient maintains the minute volume settings for VT x f, no mandatory breaths are delivered. If the patient's minute volume is insufficient, mandatory delivery of the preset tidal volume will occur until the minute volume is achieved. The method for monitoring whether or not the patient is meeting the required minute ventilation (VE) is different per ventilator brand and model, but generally there is a window of time being monitored and a smaller window being checked against that larger window.

Ventilation of neonatal patients

MMV is an optimal mode for weaning in neonatal and pediatric populations and has been shown to reduce long term complications related to mechanical ventilation.[2]

gollark: I mean, theoretically there are some upsides with central planning, like not having the various problems with dealing with externalities and tragedies of the commons (how do you pluralize that) and competition-y issues of our decentralized market systems, but it also... doesn't actually work very well.
gollark: I do, but that isn't really what "communism" is as much as a nice thing people say it would do.
gollark: I don't consider it even a particularly admirable goal. At least not the centrally planned version (people seem to disagree a lot on the definitions).
gollark: I don't think that makes much sense either honestly. I mean, the whole point of... political systems... is that they organize people in some way. If they don't work on people in ways you could probably point out very easily theoretically, they are not very good.
