Mechanical ventilation is often a life-saving intervention, but carries potential complications. A common complication of positive pressure ventilation stemming directly from the ventilator settings include volutrauma and barotrauma. [11] [12] Others include pneumothorax, subcutaneous emphysema, pneumomediastinum, and pneumoperitoneum.
Ventilator-associated pneumonia (VAP) is a type of lung infection that occurs in people who are on mechanical ventilation breathing machines in hospitals. As such, VAP typically affects critically ill persons that are in an intensive care unit (ICU) and have been on a mechanical ventilator for at least 48 hours.
Ventilator-associated lung injury (VALI) is an acute lung injury that develops during mechanical ventilation and is termed ventilator-induced lung injury (VILI) if it can be proven that the mechanical ventilation caused the acute lung injury. In contrast, ventilator-associated lung injury (VALI) exists if the cause cannot be proven.
Applied PEEP is usually one of the first ventilator settings chosen when mechanical ventilation is initiated. It is set directly on the ventilator.. A small amount of applied PEEP (4 to 5 cmH 2 O) is used in most mechanically ventilated patients to mitigate end-expiratory alveolar collapse. [6]
The volume-cycled ventilation is the simplest and most efficient of providing ventilation to a patient's airway compared to other methods of mechanical ventilation. Each inspiratory effort that is beyond the set sensitivity threshold will be accounted for and fixed to the delivery of the corresponding tidal volume.
While in many cases mechanical ventilation is a life-saving or life-preserving intervention, it also has the potential to cause harm to the patient via ventilator-associated lung injury. A number of stresses may be induced by the ventilator on the patient's lung.
In a hospital, long-term mechanical ventilation is provided by using a more complex, automated ventilator. However, a frequent use of a manual resuscitator is to temporarily provide manual ventilation whenever troubleshooting of the mechanical ventilator is needed, if the ventilator circuit needs to be changed, or if there is a loss of ...
The ventilator prevents the accumulation of carbon dioxide so that the lungs don't collapse due to the low pressure. [2] [3] The use of artificial ventilation can be traced back to the seventeenth century. There are three ways of exchanging gases in the body: manual methods, mechanical ventilation, and neurostimulation. [4]
