Mandatory Minute Ventilation

Mandatory Minute Ventilation

Mandatory Minute Ventilation (MMV) is a fan action mode in which all breaths are forced and delivered by a fan with a given frequency (f), volume or pressure, and inspiration time. In the proposed list of modes, MMV covers all methods that deliver only forced or a combination of forced and auxiliary breaths. The only difference between assisted breathing and controlled breathing is that the patient initiates assisted breathing, while the ventilator initiates forced breathing.

Mandatory Minute Ventilation was the forerunner of more modern “automatic” methods designed to change the device’s performance to achieve a specific clinical goal.

MMV guarantees certain minute ventilation, regardless of whether the patient is trying to breathe.

MMV does not provide a fixed number of breaths – no hardware cycles are performed if the patient is breathing at an adequate pace. MMV was considered as an independent method of “automatic termination” of mechanical ventilation.

It can be provided with periodic respiratory cycles with volume switching, acting only when they are required.

As an alternative to optimizing tidal volume or frequency, a pressure support level can be set for each tidal cycle.


  • In principle, MMV is almost an ideal support for pressure ventilation;
  • This mode does not force the patient to receive hardware support, although, if necessary, it is always at the ready.


  • MMV allows the development of fatigue in the process of approaching the planned value of minute ventilation;
  • Indeed, a given minute ventilation can be achieved by increasing the frequency, even when exhaustion occurs. (To warn of it, you can set an alarm to control the frequency and tidal volume);
  • The potentially excessive force also characterizes pressure-controlled volumetric control and volume support;
  • Some modes limit the maximum frequency and maintain tidal volume.

Additional respiratory problems treatment options for the best results?

The general approach to the management of stable state of respiratory system should be characterized by a gradual increase in treatment depending on the disease’s severity. There will be prescribed many different Trust Worldwide Pharmacy medications.

For patients with respiratory diseases, health education can play a significant role in improving skills, adaptability and health state. It is effective in achieving several goals, including smoking cessation.

It has been established that none of the existing drugs for COPD (one of the raspiratory diseases) can change the long-term decline in lung function characteristic of this disease. Therefore, pharmacotherapy for COPD is used to relieve symptoms and complications.

Bronchodilator drugs are central to the symptomatic management of respiratory diseases. They are prescribed as needed or on a regular basis to prevent or relieve symptoms.

The main bronchodilator drugs are 2-agonists, anticholinergics, theophylline, and a combination of two or more of these drugs.

Regular treatment with inhaled glucocorticosteroids should be prescribed only in symptomatic patients with a confirmed spirometric response to glucocorticosteroids or in patients with a predicted FEV1 of less than 50% and recurrent exacerbations requiring antibiotic or oral glucocorticosteroid treatment.

Long-term treatment with systemic glucocorticosteroids should be avoided due to the unfavorable benefit / risk ratio.

All patients with respiratory diseases benefit from exercise training programs, achieving improvements in both exercise tolerance, dyspnoea and fatigue.

It has been established that prolonged oxygen therapy (more than 15 hours a day) in patients with chronic respiratory failure improves the state considerably.
