ventilatordelivered

Ventilatordelivered is a term used to describe a medical condition where a patient experiences lung injury as a direct result of being placed on mechanical ventilation. This type of injury is also known as ventilator-induced lung injury or VILI. It can occur when the pressure or volume of air delivered to the lungs by a ventilator exceeds the lungs' capacity, causing damage to the delicate lung tissue.

Several factors can contribute to ventilatordelivered. These include high tidal volumes, excessive positive end-expiratory pressure (PEEP), rapid breathing rates, and pre-existing lung conditions such as acute respiratory distress syndrome (ARDS) or pneumonia. The mechanical forces applied by the ventilator can lead to alveolar overdistension, shear stress, and inflammation, all of which can worsen lung function.

The consequences of ventilatordelivered can range from mild inflammation to severe lung damage, including pneumothorax (collapsed lung) and pulmonary edema. Symptoms may include increased shortness of breath, worsening oxygen levels, and radiographic evidence of new infiltrates on chest X-rays.

Management of ventilatordelivered focuses on minimizing further lung injury. This often involves adjusting ventilator settings to lower tidal volumes, optimize PEEP levels, and reduce respiratory rate. Strategies such as prone positioning and the use of neuromuscular blocking agents may also be employed. Early recognition and prompt intervention are crucial to improving patient outcomes and reducing the severity of lung damage.
