Mechanical Ventilators: Uses, Benefits, Key Advantages and Risks

A Mechanical Ventilator is a device that assists a patient in breathing (ventilating) when he or she is unable to do so for any reason. There are numerous advantages, but infection is a significant concern.

What is a mechanical ventilator?

When a patient is having surgery or is unable to breathe on their own due to a critical disease, mechanical ventilation assists them in breathing (ventilating). A hollow tube (artificial airway) is inserted into the patient's mouth and down into their primary airway, or trachea, to connect them to the ventilator.

Why do we use mechanical ventilators?

A Mechanical Ventilators is used to reduce the amount of labor required to breathe until the patient's condition improves to the point where it is no longer required. The equipment ensures that the body receives enough oxygen while also removing carbon dioxide. When certain disorders hinder regular breathing, this is important.

What are the benefits of mechanical ventilation?

The following are the key advantages of Mechanical Ventilators:
  • The patient's respiratory muscles do not have to work as hard to breathe
  • The patient is given time to recover in the hopes that breathing will return to normal.
  • Assists the patient in getting enough oxygen and removing carbon dioxide.
  • Maintains a stable airway and prevents aspiration damage.

What are the risks of mechanical ventilation?

The greatest danger of Mechanical Ventilators is an infection, as bacteria can enter the lungs through the artificial airway (breathing tube). The longer mechanical breathing is required, the greater the risk of infection, which peaks around two weeks. Another concern is lung injury from overinflation or repeated opening and contracting of the lungs' tiny air sacs (Ialveoli). Patients who are unable to wean themselves off of a ventilator may require long-term support. The tube is withdrawn from the mouth and replaced with a narrower airway in the neck when this happens. A tracheostomy is a medical term for this procedure. If the patient is deemed unlikely to live, using a ventilator may prolong the dying process.
