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.
Mandatory minute ventilation (MMV) allows spontaneous breathing with automatic adjustments of mandatory ventilation to the meet the patient's preset minimum minute volume requirement. If the patient maintains the minute volume settings for V T x f, no mandatory breaths are delivered. [citation needed]
If the calculation suggests the volume target will not be met, SIMV breaths are delivered at the targeted volume to achieve the desired minute ventilation. [12] Allows spontaneous breathing with automatic adjustments of mandatory ventilation to the meet the patient’s preset minimum minute volume requirement.
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]
A normal minute volume while resting is about 5–8 liters per minute in humans. [1] Minute volume generally decreases when at rest, and increases with exercise. For example, during light activities minute volume may be around 12 litres. Riding a bicycle increases minute ventilation by a factor of 2 to 4 depending on the level of exercise involved.

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.
For example, mindfulness strategies, such as meditating or simple breathing exercises, help you turn down your heightened stress response, says Dr. Gould. Try simple three-minute breathing ...
