What is one potential complication of mechanical ventilation?

• A. Improved lung function
• B. Ventilator-associated pneumonia
• C. Enhanced metabolic rate
• D. Decreased respiratory rate

Answer: (B)

Ventilator-associated pneumonia (VAP) is a significant complication that can arise from mechanical ventilation. This condition occurs when bacteria infect the lungs, often as a result of the ventilator's presence, which can disrupt the normal protective mechanisms of the upper airways and lungs. The introduction of a breathing tube bypasses certain anatomical barriers that typically prevent pathogens from reaching the lower respiratory tract, increasing the risk of infection. VAP is particularly concerning because it can lead to longer hospital stays, increased healthcare costs, and higher morbidity and mortality rates. The mechanical ventilation process can also alter lung function over time, potentially leading to problems like atelectasis or over-distension of lung units, further heightening the risk of infection. Preventative strategies, such as maintaining proper ventilator settings, utilizing sterile techniques for intubation, and incorporating oral care protocols, are critical in reducing the incidence of VAP in mechanically ventilated patients. Understanding this complication is essential for healthcare providers involved in ventilator management and patient care.
